|
LPS-binding protein (LBP) enhanced the chitosan-induced TNF-alpha production only to a minor degree, suggesting that serum proteins other than LBP play an important role in the stimulatory effect.

CD34+ HPC can be mobilized into the peripheral blood by in vivo administration of granulocyte-colony-stimulating factor.
|
11 |
7532543
|
The aim of the current study was to determine whether functional dendritic cells could be elicited and grown in vitro from CD34+ HPC derived from bone marrow or granulocyte-colony-stimulating factor-mobilized peripheral blood.
|
12 |
7532543
|
Culture of CD34+ HPC with granulocyte-macrophage-colony-stimulating factor and tumor necrosis factor alpha yielded a heterogeneous cell population containing cells with typical dendritic morphology.
|
13 |
7532543
|
Phenotypic studies demonstrated a loss of the CD34 molecule over 1 week and an increase in cells expressing surface markers associated with dendritic cells, CD1a, CD80 (B7/BB1), CD4, CD14, HLA-DR, and CD64 (Fc gamma RI).
|
14 |
7532543
|
Function was validated in experiments showing that cultured cells could stimulate proliferation of allogeneic CD4+ and CD8+ T lymphocytes.
|
15 |
7532543
|
The derivation and expansion of dendritic cells from cultured bone marrow or granulocyte-colony-stimulating factor-mobilized CD34+ HPC may provide adequate numbers for testing of dendritic cells in clinical studies, such as vaccine and T cell therapy trials.

Cell surface marker studies for CD2 (total T cells), CD4 (helper T cells), CD8 (suppressor T cells), CD25 (activated T cells), CD20 (total B cells), CD14 (monocytes), and HLA-DR positive cell populations were measured.
|

Highly purified peripheral blood T cells containing less than 0.1% CD14+ cells and unresponsive to phytohemagglutinin (PHA), were growth-inhibited by IL-10 when stimulated with immobilized OKT3 monoclonal antibody (MoAb; 55.4% inhibition).
|
19 |
8499633
|
Secretion of IL-2 under these conditions was inhibited by IL-10 (51.5% inhibition).
|
20 |
8499633
|
Thus, IL-10 can directly inhibit growth and IL-2 production in T cells triggered by immobilized OKT3 MoAb in the absence of monocytes.

By using 70Z/3-derived pre-B-cell lines either lacking or expressing human CD14 (the LPS receptor), it was observed that expression of human CD14 imparted responsiveness to LPS but not to OspA or spirochetal lipopeptides (assessed by induction of NF-kappa B and expression of surface immunoglobulin M).
|

We show here that highly purified CD14(bright) peripheral blood monocytes supplemented with granulocyte-monocyte (GM)-CSF plus IL-4 develop with high efficacy (>95% of input cells) into DC.
|
23 |
8892615
|
They neo-expressed CD1a, CD1b, CD1c, CD80, and CD5; they massively up-regulated CD40 (109-fold) and HLA-DQ and DP (125- and 87-fold); and significantly (>5-fold) up-regulated HLA-DR, CD4, CD11b, CD11c, CD43, CD45, CD45R0, CD54, CD58, and CD59.
|
24 |
8892615
|
CD14, CD15s, CD64, and CDw65 molecules were down-regulated to background levels, and no major changes were observed for HLA class I, CD11a, CD32, CD33, CD48, CD50, CD86, CDw92, CD93, or CD97.
|
25 |
8892615
|
Monocytes cultured in parallel with GM-CSF plus TNF-alpha were more heterogeneous in expression densities but otherwise similar in their surface molecule repertoire.
|
26 |
8892615
|
Only GM-CSF plus IL-4-cultured cells were found to be potent stimulators in allogeneic and autologous MLR and they presented tetanus toxoid 100- to 1000-fold more efficiently than other cell populations tested.

The ability to induce TNF-alpha in PBMC by four clinical strains of C. neoformans, a laboratory strain (NIH 37), and the purified cryptococcal components glucuronoxylomannan (GXM), galactoxylomannan (GalXM), and mannoproteins (MP1 and MP2) were investigated under different opsonic conditions.
|
33 |
8975923
|
Normal human serum (NHS) enhanced TNF-alpha induction by whole cryptococci and the different cryptococcal components, with MP2 being the most potent TNF-alpha inducer.
|
34 |
8975923
|
In contrast, when MP1, MP2, and GalXM were incubated with HI NHS, 48, 71, and 44%, respectively, of the original TNF-alpha levels remained.
|
35 |
8975923
|
Two anti-CD14 monoclonal antibodies (60BCA and 3C10) inhibited the production of TNF-alpha induced by MP2.
|
36 |
8975923
|
The results indicate that (i) induction of TNF-alpha by C. neoformans and GXMs strongly depends on complement, (ii) MP1 and MP2 induction of TNF-alpha is facilitated by a heat-stable serum factor other than Ig, and (iii) CD14 may be involved in the induction of TNF-alpha by MP2.
|

Induction of TNF-alpha in human peripheral blood mononuclear cells by the mannoprotein of Cryptococcus neoformans involves human mannose binding protein.
|
38 |
9300722
|
We have shown previously that specific receptors on PBMCs and a serum factor other than Ab and complement are involved in the TNF-alpha response to cryptococcal mannoprotein (MP2).
|
39 |
9300722
|
Beta-Glucan laminarin produced background inhibition. mAbs against CD14, CD11b, and CD18 did not prevent FITC-MP2 binding to PBMCs, implying that these receptors are not involved in MP2 recognition by PBMCs. mAb against CD14 blocked (>90%) MP2-induced TNF-alpha release by PBMCs, while mAbs against CD11b/CD18 caused no inhibition.
|
40 |
9300722
|
Removal of human mannose binding protein (hMBP) by preincubation of serum with a specific mAb abrogated TNF-alpha induction by MP2 and strongly inhibited its binding to PBMCs.
|
41 |
9300722
|
Recombinant hMBP enhanced TNF-alpha induction by MP2 as well as binding of FITC-MP2 to PBMCs.
|
42 |
9300722
|
In addition, incubation of serum with MP2-coated beads and analysis by SDS-PAGE resulted in the detection of a protein of approximately 33/34 kDa that could be partially removed by preincubating the serum with hMBP mAb.
|
43 |
9300722
|
We conclude that hMBP is involved in the binding of MP2 to PBMCs and the release of TNF-alpha.

High enrichment of CD34+ HSCs was obtained using an immunomagnetic bead cell separation device.
|
45 |
9829733
|
After separation, the negative fraction of mobilized PBMCs from normal donors and cancer patients contained undetectable levels of CD34+ HSCs by flow cytometry.
|
46 |
9829733
|
This fraction of cells was then subjected to plastic adherence, and the adherent cells were cultured for 7 days in GM-CSF (100 ng/ml) and interleukin 4 (50 ng/ml) followed by an additional 7 days in GM-CSF, interleukin 4, and tumor necrosis factor alpha (10 ng/ml) to generate DCs.
|
47 |
9829733
|
Harvested DCs represented yields of 4.1+/-1.4 and 5.8+/-5.4% of the initial cells plated from the CD34+ cell-depleted mobilized PBMCs of normal donors and cancer patients, respectively, and displayed a high level expression of CD80, CD86, HLA-DR, and CD11c but not CD14.
|
48 |
9829733
|
Collectively, these results demonstrate the feasibility of obtaining both DCs and CD34+ HSCs from the same leukapheresis collection from G-CSF-primed normal donors and cancer patients in sufficient numbers for the purpose of combined PBSCT and immunization strategies.

B. burgdorferi similarly induced an upregulation of the IL-1beta and IL-6 cytokine genes in monocytes and the production of IL-10 and IL-6 in culture supernatants of the human monocytic cell line THP-1.
|
50 |
9864208
|
Monoclonal antibodies (MAbs) MY4 and 60bca, both of which bind to CD14 and are known to block lipopolysaccharide (LPS)-mediated cytokine production, were able to block L-OspA-mediated IL-10 and IL-6 cytokine production.

A synergistic effect of DC-TuLy and IL-2 in stimulating a T cell-dependent immune response was demonstrated by: (a) the increase of growth expansion of TILs (9.4-14.3-fold; day 21); (b) the up-regulation of the CD3+ CD56- TcR+ (both CD4+ and CD8+) cell population; (c) the augmentation of T cell-restricted autologous tumor lysis; and (d) the enhancement of IFN-gamma, tumor necrosis factor-alpha, granulocyte macrophage colony-stimulating factor, and IL-6 mRNA expression by TILs.

|
B. burgdorferi induced secretion of IL-8 by vitamin D3-matured THP-1 cells, which was inhibited by a CD14-specific mAb known to block cellular activation by LPS and the prototypic spirochetal lipoprotein, outer surface protein A.
|
57 |
10452971
|
Transfection of TLR2 into cell lines conferred responsiveness to lipoproteins, lipopeptides, and sonicated B. burgdorferi, as measured by nuclear translocation of NF-kappaB and cytokine production.
|
58 |
10452971
|
Futhermore, TLR2-dependent signaling by lipoproteins was facilitated by CD14.

During differentiation of human monocytes (CD14(+)/CD1a(-)) to CD14(-)/CD1a(+)dendritic cells (DC), a drastic decrease in PDE4 activity was observed, while activities of PDE1 and PDE3 substantially increased.
|
88 |

10689136
|
The generation of DC from blood monocytes in response to GM-CSF and IL-4 treatment was similar in cells from young and old persons.
|
91 |
10689136
|
The DC population thus obtained had a typical dendritic morphology and expressed DC surface markers, such as HLA class II, CD1a, CD11c, CD54, CD80 and CD86, but not CD14 for a period of up to three weeks in culture.
|
92 |
10689136

Cells displayed a characteristic iDC phenotype (CD1a(+), CD14(-), CD80(+), CD86(+), HLA DR(+), CD83(-)), and had potent allogeneic and antigen dependent autologous T cell-stimulatory capacity.
|
95 |
10915850

|
We developed a flow cytometric method to directly identify and isolate DCs from rhesus peripheral blood whereby a T cell depleted population negative for CD3, CD14, CD16 and CD20 but positive for CD83 yielded a cell population with surface markers, morphology, and a cytokine profile similar to human myeloid DCs.

Here we describe a novel RCC vaccine strategy that allows for the concomitant delivery of dual immune activators: G250, a widely expressed RCC associated antigen; and granulocyte/macrophage-colony stimulating factor (GM-CSF), an immunomodulatory factor for antigen-presenting cells.
|
106 |
11691814
|
When combined with interleukin 4 (IL-4; 1000 units/ml), FP (0.34 microg/ml) induces differentiation of monocytes (CD14+) into dendritic cells (DCs) expressing surface markers characteristic for antigen-presenting cells.
|
107 |
11691814
|
Up-regulation of mature DCs (CD83+CD19-; 17% versus 6%) with enhanced expression of HLA class I and class II antigens was detected in FP-cultured DCs as compared with DCs cultured with recombinant GM-CSF.
|
108 |
11691814
|
Treatment of peripheral blood mononuclear cells (PBMCs) with FP alone (2.7 microg/10(7) cells) augments both T-cell helper 1 (Th1) and Th2 cytokine mRNA expression (IL-2, IL-4, GM-CSF, IFN-gamma, and tumor necrosis factor-alpha).

Comparison of various immune manipulation strategies in parallel, bulk PBMCs treated with FP (0.34 microg/ml) plus IL-4 (1000 units/ml) for 1 week and restimulated weekly with FP plus IL-2 (20 IU/ml) induced maximal growth expansion of active T cells expressing the T-cell receptor and specific anti-RCC cytotoxicity, which could be blocked by the addition of anti-HLA class I, anti-CD3, or anti-CD8 antibodies.

These results suggest that GM-CSF-G250 FP is a potent immunostimulant with the capacity for activating immunomodulatory DCs and inducing a T-helper cell-supported, G250-targeted, and CD8+-mediated antitumor response.

It is widely believed that generation of mature dendritic cells (DCs) with full T cell stimulatory capacity from human monocytes in vitro requires 5-7 days of differentiation with GM-CSF and IL-4, followed by 2-3 days of activation.
|
169 |
12682236
|
Monocytes acquire immature DC characteristics by day 2 of culture with GM-CSF and IL-4; they down-regulate CD14, increase dextran uptake, and respond to the inflammatory chemokine macrophage inflammatory protein-1alpha.
|
170 |
12682236

Heat-killed Brucella abortus induces TNF and IL-12p40 by distinct MyD88-dependent pathways: TNF, unlike IL-12p40 secretion, is Toll-like receptor 2 dependent.
|
222 |
12874236
|
Our results show that HKBA-mediated induction of IL-12p40 and TNF is dependent on the adapter molecule MyD88.
|
223 |
12874236
|
To identify the TLR involved in HKBA recognition, we examined HKBA responses in TLR2- and TLR4-deficient animals.
|
224 |
12874236
|
TNF responses to HKBA were TLR4 independent; however, the response in TLR2-deficient mice was significantly delayed and reduced, although not completely abolished.
|
225 |
12874236
|
Studies using Chinese hamster ovary/CD14 reporter cell lines stably transfected with either human TLR2 or human TLR4 confirmed the results seen with knockout mice, namely TLR2, but not TLR4, can mediate cellular activation by HKBA.
|
226 |
12874236
|
In addition, human embryonic kidney 293 cells, which do not respond to HKBA, were made responsive by transfecting TLR2, but not TLR4 or TLR9.
|
227 |
12874236
|
Taken together, our data demonstrate that MyD88-dependent pathways are crucial for activation by HKBA and that TLR2 plays a role in TNF, but not IL-12p40 pathways activated by this microbial product.

We showed previously that DC derived from a monocyte subset expressing CD16 (16+mDC) stimulated allogeneic naïve T lymphocytes to secrete higher levels of IL-4 than DC derived from regular CD14(high)CD16(-) monocytes (16-mDC).
|
268 |

Peripheral blood CD14+ monocytes from multiple myeloma (MM) patients can be induced to differentiate into fully functional, mature, CD83+ dendritic cells (DCs) which are highly efficient in priming autologous T lymphocytes in response to the patient-specific tumor idiotype (Id).
|
273 |
15359643
|
Cells were then cultured, according to Good Manufacturing Practice guidelines, in FCS-free medium in cell culture bags, and differentiated to DCs with GM-CSF plus IL-4 followed by TNF-alpha or, more recently, by a cocktail of IL-1beta, IL-6, TNF-alpha and prostaglandin-E2.
|
274 |
15359643
|
Notably, the cytokine cocktail induced a significantly higher percentage and yield (31+/-10.9 of initial CD14+ cells) of DCs than TNF-alpha alone, secretion of larger amounts of IL-12, potent stimulatory activity on allogeneic and autologous T cells.

Generation of dendritic cells from rabbit bone marrow mononuclear cell cultures supplemented with hGM-CSF and hIL-4.
|
280 |
15621303
|
Here we show that DCs can be generated in vitro from rabbit bone marrow mononuclear cells (BMMCs) cultured in the presence of the human cytokines GM-CSF and IL-4 and matured with lipopolysaccharide (LPS).
|
281 |
15621303
|
These cells show upregulation of MHC class II and CD86, as well as downregulation of CD14, do not have non-specific esterase activity, are able to perform receptor-mediated endocytosis, and are potent stimulators of allogeneic T cell proliferation in mixed lymphocyte reactions.
|
282 |
15629885
|
Upon stimulation with LPS, in comparison with young MPhi, aged MPhi secreted reduced amounts of IL-6, tumor necrosis factor alpha, IL-1beta, and IL-12, cytokines necessary for B cells to respond to TI Ag.
|
283 |
15629885
|
As aged MPhi have a reduced number of cells expressing Toll-like receptor 4 and CD14, the imbalance in cytokine production might be partly a result of fewer cells expressing key components of the LPS receptor complex.
|
284 |
15664921
|
Maturation was evaluated by the ability of MPs to facilitate expression of costimulatory molecules such as CD40, CD86, CD83, and major histocompatibility complex classes I and II and to inhibit receptors such as CD14, CD16, and CD32.
|
285 |
15664921
|
Activation of DCs was measured by the capacity of MPs to promote interleukin-12 and tumor necrosis factor alpha secretion.

The current study identifies a novel class of single-stranded oligoribonucleotides (ORN) containing unmethylated CpG motifs and a poly(G) run at the 3' end (CpG ORN) that directly stimulate human CD14+CD11c+ monocytes but not dendritic cells or B cells.
|

A soluble LAG-3 (CD223) molecule (sLAG-3) is a natural, high-affinity ligand for MHC class II.
|
295 |
15720438
|
It is known to induce maturation of monocyte-derived dendritic cells in vitro and is used as a vaccine adjuvant to induce CD4 T helper type 1 responses and CD8 T-cell responses in vivo.
|
296 |
15720438
|
Here, we demonstrate that sLAG-3 (but not an MHC class II-specific monoclonal antibody) reduces the differentiation of monocytes into macrophages in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) as well as their differentiation into dendritic cells in the presence of GM-CSF and interleukin-4, as shown by a decrease in CD14 and CD1a expression, respectively.
|
297 |
15762884
|
We conclude that CD86 expression on CD14(+) monocytes of DR0301- and DR07-homozygous poor responders is not deficient and cannot be the mechanism underlying the non-responsiveness of these subjects.

Abstract Heat shock proteins (Hsp) can deliver antigen into the major histocompatibility complex class I presentation pathway of antigen-presenting cells (APC), a process called cross priming, thus stimulating antigen-specific CD8+ T-cell reactions.
|
299 |
15787741

Nonreplicating recombinant vaccinia virus expressing CD40 ligand enhances APC capacity to stimulate specific CD4+ and CD8+ T cell responses.
|
302 |
15812230
|
Recently, we and others have demonstrated, in vitro and in vivo, that coexpression of CD80 and CD86 costimulatory molecules enhances the immunogenic capacity of a recombinant vaccinia virus (rVV) encoding different tumor-associated antigens.
|
303 |
15812230
|
To further investigate the capacity of these vectors to provide ligands for different costimulatory pathways relevant in the generation of T cell responses, we constructed a recombinant virus (rVV) expressing CD40 ligand or CD154 (CD154rVV).
|
304 |
15812230
|
Upon binding the CD40 receptor expressed on antigen presenting cells (APC), this molecule, physiologically expressed on activated CD4+ T cells, increases their antigen presentation and immunostimulatory capacities.
|
305 |
15812230
|
CD154rVV infection of autologous fibroblasts, monocytes, or iDC promoted the expression of a number of cytokines, including GM-CSF, TNF-alpha, and IL-15 in iDC.
|
306 |
15812230
|
Most importantly, IL-12 p40 gene expression and protein secretion were induced by CD154rVV but not by wild-type VV (WT VV) in either CD14+ cells or iDC, and these effects could be blocked by anti-CD40 monoclonal antibodies.
|
307 |
15812230
|
Furthermore, phenotypic characterization of CD154rVV infected iDC revealed enhanced expression of CD83 and CD86 surface markers as compared with wild-type vaccinia virus infection.
|
308 |
15812230
|
However, cytokine genes typically expressed by T cell receptor triggered T cells such as those encoding IL-2 and IFN-gamma, or T cell proliferation, were detectable to a significantly higher extent in CD154rVV infected cultures, as compared with WT VV.
|
309 |
15812230

A population of cells exhibiting bona fide dendritic cell (DC) morphological and functional characteristics was obtained by treating Aotus spp. monocytes with human IL-4 and GM-CSF.
|
311 |
15837362
|
Although the purity of mature DCs was relatively low IL-4/GM-CSF-treated monocytes (hereafter called Aotus spp.
|
312 |
15837362
|
DCs) down-regulated CD14 and up-regulated discrete levels of CD80, MHC-Class II and CD1b molecules in response to different maturation stimuli.
|
313 |
15867395
|
Increased NK activity was associated with a raise in CD3-CD56+ NK and/or CD3+CD56+ NK-like T cells, displaying enhanced expression of NKG2D and/or NKp46 receptors.
|
314 |
15867395
|
Up-regulated expression of CD83 and CD40 and increased interleukin-12 release on stimulation were observed in CD14+ cells from post-HSP96 peripheral blood mononuclear cells, suggesting an indirect pathway of NK stimulation by HSP96-activated monocytes.
|
315 |
15877606
|
Monocyte-derived dendritic cells (mDC), the most frequently applied DC subset in clinical studies, which can be obtained easily from peripheral blood monocytes after incubation with GM-CSF and IL-4, have not been clearly demonstrated to be activated by CpG oligodeoxynucleotides (ODN).
|
316 |
15877606
|
However, we did not observe increased expression of maturation-associated and functionally relevant surface antigens (CD14, HLA-DR, CD40, CD83, CD80 and CD86), significant secretion of IL-12 and IFN-alpha in culture supernatant, or enhanced antitumour activation of cytokine-induced killer cells.

15879106
|
High levels of the Th1-attracting, HIV-1-inhibitory chemokines, CCL3/MIP-1alpha and CCL4/MIP-1beta, were induced in human primary monocytes when CpG- or non-CpG-ODN was combined with GM-CSF, but not with IL-4 or IFN-gamma.
|
319 |
15879106
|
Cells treated with non-CpG PS-ODN and GM-CSF expressed dendritic cell marker CD83 and high levels of HLA-DR and costimulatory molecules, and were CD14(-) or CD14(dim), consistent with monocyte differentiation into a dendritic cell phenotype.
|

|
Despite normal basal expression of Toll-like receptors and membrane CD14, innate immune responses of neonatal mononuclear cells to lipopolysaccharide are characterized by markedly reduced release of the pro-inflammatory Th1-polarizing cytokines TNF-alpha and interferon-gamma with relative preservation of anti-inflammatory Th2-polarizing cytokines.
|
323 |
16029505
|
The results demonstrate that as monocytes passed through the column matrix, they became activated and differentiated into semi-mature DC expressing significantly increased levels of class II, CD83 and CD86 (markers associated with maturing DC) and reduced expression of the monocyte markers CD14 and CD36.
|
324 |
16029505
|
After CD8 T cells were stimulated by DC loaded with malignant cells, they mediated increased apoptosis of residual CTCL cells and TNF-alpha secretion indicating development of enhanced cytolytic function.

327 |
16037410
|
Recently, it has been described that DC can also be generated in the presence of IL-3 and interferon (IFN)-beta and that these DC are efficiently matured using polyriboinosinic polyribocytidylic acid (I3-DC).
|
328 |
16037410
|
Phenotypic characterization of the DC revealed differences in the expression of the monocyte marker CD14 and the maturation marker CD83.
|
329 |
16037410
|
Low expression of CD14 and high expression of CD83 characterized G4-DC, whereas I3-DC displayed intermediate expression of CD14 and CD83.
|
330 |
16037410
|
Upon CD40 ligation, G4-DC produced lower amounts of IFN-alpha and pulmonary and activation-regulated chemokine, similar amounts of IL-6, macrophage-inflammatory protein (MIP)-1alpha, and MIP-1beta, and higher amounts of IL-12 p70, tumor necrosis factor alpha, and MIP-3beta than I3-DC.
|
331 |
16037410
|
Finally, in vitro stimulations showed that fresh and frozen peptide-loaded I3-DC are more potent inducers of Melan-A-specific CD8(+) T cell responses than G4-DC.

Francisella tularensis variants were readily taken up by fresh human CD14(+) monocytes, inducing the release of IL-1beta, as well as IL-8, in a time- and dose-dependent fashion.
|
340 |
16373510
|
Blocking bacterial escape from the phagosome into the cytosol also decreased IL-1beta but not IL-8 release.

We recently demonstrated that the pattern recognition receptors (PRRs) toll-like receptor 2 (TLR2), TLR4, and CD14 are expressed in mouse colonic epithelium in a compartmentalized manner.
|
342 |
16426010
|
Interestingly, while TLR2, TLR4, and CD14 were up-regulated in the inflamed colon, TLR5 was down-regulated at both the mRNA and protein levels.
|
343 |
16426010
|
Additional in vitro studies using a mouse cell line, Colon-26, showed that gamma interferon (IFN-gamma) time- and dose-dependently down-regulates TLR5.
|
344 |
16426010
|
TLR5 expression is down-regulated in vivo during acute and chronic DSS-induced colitis, in contrast to the expression of TLR2, TLR4, and CD14.
|
345 |
16426010

Interestingly, while TLR2, TLR4, and CD14 were up-regulated in the inflamed colon, TLR5 was down-regulated at both the mRNA and protein levels.
|

Myeloid cells had a CD4+CD11b+CD11c+CD16+CD123(low)HLA-DR- phenotype, expressed myeloperoxidase, and included a population of M-CSFR+ monocyte-lineage committed cells.
|
358 |
16493050
|
Further culture of myeloid cells in serum-free medium with GM-CSF and IL-4 generated cells that had typical dendritic morphology; expressed high levels of MHC class I and II molecules, CD1a, CD11c, CD80, CD86, DC-SIGN, and CD40; and were capable of Ag processing, triggering naive T cells in MLR, and presenting Ags to specific T cell clones through the MHC class I pathway.

Induction of kappaB-driven transcriptional activity by 2.5 mug ml(-1) F. tularensis LPS isolated by phenol-water and ether-water extraction, was observed in cells transfected with Toll-like receptor (TLR) 4 and MD-2, although CD14 was required for optimal induction.
|
363 |
16574669
|
Conversely, TLR2, TLR2/TLR1 or TLR2/TLR6 transfected cells did not show kappaB-driven transcriptional activity in the presence of F. tularensis LPS.
|
364 |
16574669
|
Concentrations of 5-10 mug ml(-1) F. tularensis LPS elicited a similar pattern of mRNA and protein induction than 0.1 mug ml(-1) E. coli LPS, including the expression of CXC chemokines (IL-8, Gro and IFN-gamma-inducible protein-10); CC chemokines (monocyte chemoattractant protein-1 and -2, macrophage-derived chemoattractant, macrophage inflammatory protein-1alpha and -1beta and RANTES (regulated upon activation, normal T cell expressed and secreted) and pro-inflammatory cytokines (IL-6 and tumor necrosis factor alpha).

Immunization of stage IV melanoma patients with Melan-A/MART-1 and gp100 peptides plus IFN-alpha results in the activation of specific CD8(+) T cells and monocyte/dendritic cell precursors.
|
366 |
16651452
|
We have carried out a pilot phase I-II trial to determine the effects of IFN-alpha, administered as an adjuvant of Melan-A/MART-1:26-35(27L) and gp100:209-217(210M) peptides, on immune responses in stage IV melanoma patients.
|
367 |
16651452
|
In five of the seven evaluable patients, a consistent enhancement of CD8(+) T cells recognizing modified and native MART-1 and gp100 peptides and MART-1(+)gp100(+) melanoma cells was observed.
|
368 |
16651452
|
In all patients, treatment augmented significantly the percentage of CD14(+) monocytes and particularly of the CD14(+)CD16(+) cell fraction.
|
369 |
16651452
|
An increased expression of CD40 and CD86 costimulatory molecules in monocytes was also observed.
|
370 |
16651452
|
Notably, postvaccination monocytes from two of the three patients showing stable disease or long disease-free survival showed an enhanced antigen-presenting cell function and capability to secrete IP10/CXCL10 when tested in mixed leukocyte reaction assays, associated to a boost of antigen and melanoma-specific CD8(+) T cells.

Increase of circulating CD8+CD57+ lymphocytes after measles infection but not after measles vaccination.
|
373 |
16805321
|
A cell population that could be involved in this process is the CD8CD57 double-positive lymphocyte subset (CD8+CD57+), known to be significantly expanded in some viral infections, e.g. human immunodeficiency virus (HIV) infection.
|
374 |
16805321
|
We therefore studied the level of CD8+CD57+ lymphocytes during measles infection and measles vaccination.
|
375 |
16805321
|
Blood samples were analysed for the proportion of peripheral blood mononuclear cells carrying both CD8 and CD57, and for other cell surface markers (CD4, CD14, CD3, CD16(CD56) or CD20).
|
376 |
16805321
|
No corresponding change in CD8+CD57+ lymphocytes was noted in MMR-vaccinated children or in healthy controls.
|
377 |
16805321
|
Since CD8+CD57+ lymphocytes could be related to the immunosuppression seen in some viral infections, our finding of elevated CD8CD57 double-positive lymphocytes during acute measles infection would suggest that this population of lymphocytes is involved in measles-induced immunosuppression.

Treatment of human monocytes with S. gordonii but not latex beads induced a clear up-regulation of CD83, CD40, CD80, and CD54 and the down-regulation of CD14.
|
379 |
16960116
|
Furthermore, bacterial treatment stimulated an increased expression of Toll-like receptor 5 (TLR5), TLR6, and TLR7, production of the proinflammatory cytokines tumor necrosis factor alpha and interleukin 1 beta, and reduction of the phagocytic activity.

Human peripheral blood CD14(+) monocytes were purified by using a magnetic separation column and cultured with GM-CSF and IL-4 to differentiate into immature DCs (iDCs).
|
413 |
17532057
|
In the presence of Talpha1, iDC surface markers CD40, CD80, MHC class I and class II molecules were significantly upregulated as measured by flow cytemotry analysis.
|
414 |
17532057
|
Thus, Talpha1 significantly enhances DC differentiation, activation, and functions from human peripheral blood CD14(+) monocytes possibly through a mechanism of the activation of p38 MAPK and NFkappaB pathways.

Peripheral blood monocytes were cultured in vitro with GM-CSF, IL-4 for 6 days, then TNF-(the TNF-group) or TNF-, IL-1, IL-6, PGE2 (the cytokine mixture group) were added to promote maturation.
|
419 |
17641838
|
Cell number was counted by hematology analyzer, and phenotype study (CD1a, CD14, CD83) was carried out by flow cytometry, and the function of DCs was examined by mixed lymphocyte reaction.
|
420 |
17641838
|
The phenotypes were as follows: CD1a+ (74.65+/-4.45)%, CD83+ (39.50+/-4.16)%, CD14+ (2.90+/-1.76)% in TNF-alpha group, and CD1a+ (81.86+/-5.87)%, CD83+ (81.65+/-6.36)%, CD14+ (2.46+/-1.68)% in the cytokine mixture group.
|
421 |
17641838

CD14+ antigen-presenting cells in human dermis are less mature than their CD1a+ counterparts.
|
427 |
17804688
|
We recently demonstrated that three antigen-presenting cell (APC) subsets exist in the healthy human dermis, CD14(+) and CD1a(+) dermal APCs and migratory dermal Langerhans cells.
|
428 |
17804688
|
Here, we extend these findings by defining CD208 as an exclusive marker of migratory dermal Langerhans cells, confirming that migratory dermal Langerhans cells (CD1a(high) CD207(+) CD208(+)) and CD1a(+) dermal APCs (CD1a(mid) CD207(-) CD208(-)) are two distinct APC populations.
|
429 |
17804688

Using flow cytometry and multicolor fluorescence immunohistochemistry, we demonstrated that there were striking differences between CD1a(+) and CD14(+) dermal APCs in their expression of pattern recognition receptors and maturation markers.
|
430 |
17804688
|
Expression of Toll-like receptor (TLR) 2, CD206 and CD209 was largely restricted to CD14(+) dermal APCs.
|
431 |
17804688
|
Consistent with these observations, most CD14(+) dermal APCs expressed an immature phenotype when compared with CD1a(+) dermal APCs, which expressed high levels of the maturation marker CD83 on their cell surface.
|
432 |
17804688
|
However, a subset of CD14(+) dermal APCs also expressed cell-surface CD83, associated with a loss of cell-surface TLR2, suggesting that they have the capacity to mature.
|
433 |
17804688

Here, we extend these findings by defining CD208 as an exclusive marker of migratory dermal Langerhans cells, confirming that migratory dermal Langerhans cells (CD1a(high) CD207(+) CD208(+)) and CD1a(+) dermal APCs (CD1a(mid) CD207(-) CD208(-)) are two distinct APC populations.

Expression of Toll-like receptor (TLR) 2, CD206 and CD209 was largely restricted to CD14(+) dermal APCs.
|
467 |
17804688
|
Consistent with these observations, most CD14(+) dermal APCs expressed an immature phenotype when compared with CD1a(+) dermal APCs, which expressed high levels of the maturation marker CD83 on their cell surface.
|
468 |
17804688
|
However, a subset of CD14(+) dermal APCs also expressed cell-surface CD83, associated with a loss of cell-surface TLR2, suggesting that they have the capacity to mature.
|
469 |
17804688

CD14(+) dermal APCs are therefore the dominant cutaneous APC population capable of sensing ligands recognized by CD206, CD209 and TLR2 and subsequently may have the potential to mature.

|
502 |
18049335

ICAM-1 upregulation on human monocytes by the LOS required surface CD14, TLR4, NF-kappaB p65 and c-Jun N-terminal kinase (JNK) activity.
|
515 |
18363879
|
Our study also revealed that the LOS-induced surface ICAM-1 expression was partially mediated through a TNF-alpha dependent autocrine mechanism and could be further augmented by lipopolysaccharide-binding protein in serum.

Low doses of alpha-defensins1-3 up-regulated CD83, CD86 and HLA-DR expression, increased TNF-alpha, IL-1beta, IL-12p40, IL-10 and IL-8 secretion, and slightly augmented allostimulatory capacity.
|
554 |

Using an endotoxin free rHagB preparation, our results show that stimulation of murine bone marrow-derived DC with rHagB leads to upregulation of the costimulatory molecules CD86 and CD40, activation of p38 and ERK MAP kinases, transcription factors NF-kappaB, CREB and IRF-3 and the production of IL-6, TNF-alpha, IL-12p40 and to a lesser extent IL-10 and IFN-beta.

Since natural lipid A from bacterial LPS depends on membrane-bound (mCD14) or soluble CD14 for its TLR4 ligand activity, we investigated the involvement of both forms of CD14 in the responses elicited by CRX-527.
|
607 |
20039305
|
First, we found that CRX-527 induces NF-kappaB and interferon regulatory factor-3 (IRF-3) activation in human embryonic kidney cells transfected with TLR4 and MD-2 genes alone, whereas the responses to LPS require either co-transfection of the gene encoding mCD14 or addition of soluble CD14.

Incorporation of CD40 ligand into SHIV virus-like particles (VLP) enhances SHIV-VLP-induced dendritic cell activation and boosts immune responses against HIV.
|
640 |
20471443
|
Engagement of CD40 with CD40L induces dendritic cell (DC) maturation and activation, thereby promoting immune responses.
|
641 |
20471443
|
We found that CD83, CD40, and CD86 were significantly up-regulated and significantly increased cytokines production were observed after hCD40L/SHIV-VLP treatment in human CD14(+) monocyte-derived DCs as compared to SHIV-VLP treatment.
|
642 |
20471443
|
Mice immunized with mCD40L/SHIV-VLP showed more than a two-fold increase in HIV Env-specific IgG antibody production, an increase in SIV Gag and HIV Env-specific IFN-gamma and IL-4 producing cells, and an increase in HIV Env-specific cytotoxic activity compared to that in SHIV-VLP immunized mice.
|
643 |
20471443
|
Furthermore, multifunctional CD4(+) Th1 cells, which simultaneously produce IFN-gamma, IL-2 and TNF-alpha triple cytokines, and CD8(+) T-cells, which produce IFN-gamma were elevated in the mCD40L/SHIV-VLP immunized group.
|

Meningococcal CPS induced a dose-dependent release of cytokines (TNF-α, IL-6, IL-8, and CXCL10) and NO from human and murine macrophages, respectively.
|
652 |
21191086
|
CPS induced IL-8 release from HEK cells stably transfected with TLR2/6, TLR2, TLR2/CD14, and TLR4/MD-2/CD14 but not HEK cells alone. mAb to TLR2 but not an isotype control antibody blocked CPS-induced IL-8 release from HEK-TLR2/6-transfected cells.
|
653 |
21191086
|
A significant reduction in TNF-α and IL-8 release was seen when THP-1- and HEK-TLR4/MD-2-CD14- but not HEK-TLR2- or HEK-TLR2/6-transfected cells were stimulated with CPS in the presence of Eritoran (E5564), a lipid A antagonist that binds to MD-2, and a similar reduction in NO and TNF-α release was also seen in RAW 264.7 cells in the presence of Eritoran.

Targeting of IL-2 and GM-CSF immunocytokines to a tumor vaccine leads to increased anti-tumor activity.
|
664 |
21424118
|
Fusion proteins combining antibodies with cytokines such as IL-2 and GM-CSF appear to be promising reagents for tumor therapy.
|
665 |
21424118
|
The two fusion proteins bsF-GMCSF and tsHN-IL2-GM-CSF, binding, respectively, to the viral fusion protein (F) or to hemagglutinin-neuraminidase (HN) expressed on the surface of the vaccine cells and containing GM-CSF or GM-CSF and IL-2-activities were produced by recombinant antibody technology.
|
666 |
21424118
|
Furthermore, it was shown that CD14+ monocytes could be activated by the GM-CSF cytokine fused within the recombinant proteins and that they contributed essentially to the antitumor effect in the TNA.
|
667 |
21424118

In contrast, CD11c(Hi)MHC Class II(+) myeloid cells remained numerically unchanged with age but DCs (CD13(+), CD26(+), CD205(+)) were enriched and macrophages (CD14(+), CD172a(+)) were depleted in older animals.

Moreover, activation of monocytes and mDC with live BCG reduced expression levels of CD14 and CD11c, respectively, necessitating optimization of staining conditions to reliably measure these lineage markers.

To study the mechanisms by which this occurs, we transfected HEK293T cells with plasmids encoding TLR4, CD14, and MD2 (three components of the LPS receptor complex), as well as a NFκB luciferase reporting system.

Reduced frequency of a CD14+ CD16+ monocyte subset with high Toll-like receptor 4 expression in cord blood compared to adult blood contributes to lipopolysaccharide hyporesponsiveness in newborns.
|
724 |
23595503
|
To better understand the mechanistic basis for this age-related difference in innate immunity, we compared tumor necrosis factor alpha (TNF-α) production by monocytes from cord blood (CB) and adult blood (AB) in response to LAM (lipoarabinomannan from Mycobacterium tuberculosis, a TLR2 ligand) and LPS (lipopolysaccharide from Escherichia coli, a TLR4 ligand).
|
725 |
23595503
|
LPS or LAM-induced TNF-α production was 5 to 18 times higher in AB than in CB monocytes, whereas interleukin-1α (IL-1α) stimulated similar levels of TNF-α in both groups, suggesting that decreased responses to LPS or LAM in CB are unlikely to be due to differences in the MyD88-dependent signaling pathway.
|
726 |
23595503
|
This impaired signaling was attributable, in part, to lower functional TLR4 expression, especially on CD14(+) CD16(+) monocytes, which are the primary cell subset for LPS-induced TNF-α production.
|
727 |
23595503
|
Importantly, the frequency of CD14(+) CD16(+) monocytes in CB was 2.5-fold lower than in AB (P < 0.01).
|
728 |
23595503
|
CB from Kenyan newborns sensitized to parasite antigens in utero had more CD14(+) CD16(+) monocytes (P = 0.02) and produced higher levels of TNF-α in response to LPS (P = 0.004) than CB from unsensitized Kenyan or North American newborns.
|
729 |
23595503
|
Thus, a reduced CD14(+) CD16(+) activated/differentiated monocyte subset and a correspondingly lower level of functional TLR4 on monocytes contributes to the relatively low TNF-α response to LPS observed in immunologically naive newborns compared to the response in adults.

We found that lentivirus-mediated transduction of cMYC along with BMI1 induced proliferation of CD14(+) monocytes derived from 9 out of 12 blood donors, and we named the monocyte-derived proliferating cells CD14-ML.
|

As the TLR4 activity of natural TLR4 ligands (lipopolysaccharide, LPS and its biologically active part, the lipid A) depends on both the structure of endotoxin aggregates in solution and on single-molecule interaction with MD-2 and CD14 receptors, the rational design of TLR4 modulators should in principle take into account both these factors.

Injection of either fluorescently-labelled ACRs or blebs alone did not affect the number or distribution of migrated DC subsets from skin biopsies after 48 hours, but resulted in a general up-regulation of the co-stimulatory molecules CD83 and CD86 on skin DCs that had ingested apoptotic material.

We have previously shown that i.d. administration of GM-CSF and IL-4 resulted in preferential migration of a mature and highly T cell-stimulatory CD11hiCD1a+CD14- dermal DC subset.
|
864 |
25610730
|
Here, we found that co-injection of GM-CSF and IL-4 together with either ACRs or blebs resulted in uptake efficiencies within this dermal DC subset of 7.6% (±6.1%) and 19.1% (±15.9%), respectively, thus revealing a significantly higher uptake frequency of blebs (P < 0.02).
|
865 |

We recently reported the identification of Δ42PD1, a novel alternatively spliced isoform of human PD1 that induces the production of pro-inflammatory cytokines from human peripheral blood mononuclear cells and enhances HIV-specific CD8(+) T cell immunity in mice when engineered in a fusion DNA vaccine.
|
873 |
25692916

DC-derived IL-15 (DCIL-15) notably has the capacity to activate DC, to substitute for CD4+ Th and to potentiate vaccine efficacy making IL-15-based therapies attractive treatment options.
|
876 |
25941586
|
We observed in transplantable melanoma, glioma and metastatic breast carcinoma models that DCIL-15-based DNA vaccines in which DC specifically express IL-15 and simultaneously produce tumor Aghsp70 were able to mediate potent therapeutic efficacy that required both host Batf3+ DC and CD8+ T cells.
|
877 |
25941586

|
CD14+ DC emigrating from human skin explants genetically-immunized by IL-15 and Aghsp70 were more effective than similar DC emigrating from the explants genetically-immunized by Aghsp70 in the presence of rIL-15 in expressing membrane-bound IL-15/IL-15Rα and activating CD8+ T cells.

Freshly isolated or cryopreserved MDSCs from mobilized monkeys incorporated in cultures of anti-CD3- and anti-CD28-stimulated autologous T cells markedly suppressed CD4(+) and CD8(+) T cell proliferation and cytokine secretion (interferon γ, IL-17A).
|
889 |
26372923
|
Moreover, these MDSCs enhanced CD4(+)CD25(hi)Foxp3(+) regulatory T cell (Treg) expansion while inhibiting proliferation of activated memory T cells and increasing Treg relative to effector and terminally differentiated memory T cells.
