|
Several cytokines, especially stem cell factor (SCF) and FLT3-ligand (FL), have been identified as essential to produce large numbers of myeloid precursors and even to increase DC yield obtained by the action of granulocyte-macrophage colony-stimulating factor (GM-CSF) and tumor necrosis factor alpha (TNF-alpha).
|
41 |
15342937
|
We report here that in the absence of serum, SCF, FL, and thrombopoietin (TPO) plus interleukin-6 (IL-6) and SCF, FL, and TPO plus IL-3 were able to generate CD14+CD1a- and CD14- CD1a+ myeloid DC precursors from CD34+ cells, but IL-6 had an inhibitory effect on the generation of CD14- CD1a+ cells.
|
42 |
15342937
|

For example, it is evident that HIV can interact concomitantly with non-LC dendritic cells in two separate and distinct ways: a CD4- and CCR5-dependent infection pathway and a CD4- and CCR5-independent capture pathway mediated by DC-SIGN, a C-type lectin molecule.

Although our results indicate that DC-SIGN is not the major receptor for VLP in DC, this interaction contributes to the activation of DC surface antigens (HLA class I) and of various cytokines/chemokines, particularly TNF-alpha, IL-6, and RANTES.

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.
|
120 |
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.

CIRE, mouse DC-specific intracellular adhesion molecule 3 grabbing non-integrin (DC-SIGN) is predominantly expressed on pDCs and at a higher level on pDCs from the adult compared to newborn MLNs. cDCs with a higher capacity to induce the proliferation of naïve CD4+ T cells than pDCs, triggered CD4+ T cells to produce interferon-gamma whereas pDCs triggered them to release interleukin-10.

In this study, we showed that ovalbumin (OVA) protein-pulsed DC (DC(OVA))-derived EXO (EXO(OVA)) displayed MHC class I-OVA I peptide (pMHC I) complexes, CD11c, CD40, CD80, CCR7, DEC205, Toll-like receptor 4 (TLR4), TLR9, MyD88 and DC-SIGN molecules, but at a lower level than DC(OVA).
|
127 |
17073943
|
EXO(OVA) can be taken up by DC through LFA-1/CD54 and C-type lectin/mannose (glucosamine)-rich C-type lectin receptor (CLR) interactions.
|
128 |
17073943

DEC-205 receptor on dendritic cells mediates presentation of HIV gag protein to CD8+ T cells in a spectrum of human MHC I haplotypes.
|
130 |
17229838
|
Optimal HIV vaccines should elicit CD8+ T cells specific for HIV proteins presented on MHC class I products, because these T cells contribute to host resistance to viruses.
|
131 |
17229838
|
To extend this finding to humans, we introduced the HIV p24 gag protein into a mAb that targets DEC-205/CD205, an endocytic receptor of DCs.
|
132 |
17229838
|
We then assessed cross-presentation, which is the processing of nonreplicating internalized antigen onto MHC class I for recognition by CD8+ T cells.
|
133 |
17229838
|
Low doses of alphaDEC-gag, but not control Ig-gag, stimulated proliferation and IFN-gamma production by CD8+ T cells isolated from the blood of HIV-infected donors. alphaCD205 fusion mAb was more effective for cross-presentation than alphaCD209/DC-SIGN, another abundant DC uptake receptor.
|
134 |
17229838
|
Our results, based on humans with highly polymorphic MHC products, reveal that DCs and DEC-205 can cross-present several different peptides from a single protein.

CD14+ antigen-presenting cells in human dermis are less mature than their CD1a+ counterparts.
|
158 |
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.
|
159 |
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.
|
160 |
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.
|
161 |
17804688
|
Expression of Toll-like receptor (TLR) 2, CD206 and CD209 was largely restricted to CD14(+) dermal APCs.
|
162 |
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.
|
163 |
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.
|
164 |
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.
|
165 |

CD68 expression was largely restricted to a subset of CD14(+) dermal APCs, while both CD14(+) and CD1a(+) dermal APCs expressed CD11b and CD11c.

A high-mannose form of gp100, as protein or as tumor lysate, not only interacted specifically with DC through DC-SIGN but also resulted in an enhanced antigen presentation to gp100-specific CD4(+) T cells.

Gp120 from the HIV-1 strain JR-FL induced IL-10 expression in MDDCs from 62% of donors, via a mannose C-type lectin receptor(s) (MCLR).
|
177 |
17983270
|
The mannose-binding protein cyanovirin-N, the 2G12 mAb to a mannose-dependent gp120 epitope, and MCLR-specific mAbs inhibited IL-10 expression, as did enzymatic removal of gp120 mannose moieties, whereas inhibitors of signaling via CD4, CCR5, or CXCR4 were ineffective.
|

Gp120-stimulated IL-10 production correlated with DC-SIGN expression on the cells, and involved the ERK signaling pathway.

We recently showed that the CD34(+) acute myeloid leukemia cell line MUTZ-3 supports differentiation of both DC-SIGN(+) IDC and Langerin-positive Birbeck granule-expressing LC.
|
180 |
18354176

This might be related to the observed inability of LC to release T cell stimulatory cytokines such as IL-12p70, IL-23, and IL-15.

CD4(+) and CD8(+) T cells and a mixed population of plasmacytoid and myeloid dendritic cells (DCs), including cells expressing the C-type lectin receptor DC-SIGN, persisted at sites of HSV-2 reactivation for months after healing, even with daily antiviral therapy.
|
188 |
19648930

In the genital mucosa, two main subsets of DCs are present: epithelial LCs capture and degrade HIV-1 through C-type lectin Langerin, whereas subepithelial DCs express DC-SIGN, which facilitates HIV-1 transmission to T cells.
|
192 |
20042470
|
We show that carbohydrate structures blocking DC-SIGN but not Langerin are potential microbicides, as they prevent HIV-1 transmission by DCs but do not affect the antiviral function of LCs.

CD4+CD25+ regulatory T cells (Tregs) are known to inhibit immune responses to antigens.
|
203 |
21316501
|
Our results demonstrate that Tregs down-regulate the expression and uptake of antigens via C-type lectin-like receptors CD206 and DC-SIGN, restrain the pinocytosis process of DC and augment the expression of FcγRIIB, an inhibitory Fcγ receptor the engagement of which by IgG-bound antigens leads to inhibition of DC activation.

Here, its effects on the humoral and cellular anti-ovalbumin (OVA) responses in C57BL/6 mice are presented.OVA antibody class and subclass responses were determined by ELISA, the generation of anti-OVA CTLs was assessed in (51)Cr release assays using in vitro-stimulated immune spleen cells from the different groups of mice as effector cells and OVA peptide-fed RMA-S cells as targets, and evaluation of the type of Th cell response was done by IFN-γ, IL-2, IL-4 and IL-5 ELISpot assays.Immunizations with the OVA - mannosylated PSGL-1/mIgG(2b) conjugate, especially when combined with the AbISCO®-100 adjuvant, lead to faster, stronger and broader (with regard to IgG subclass) OVA IgG responses, a stronger OVA-specific CTL response and stronger Th1 and Th2 responses than if OVA was used alone or together with AbISCO®-100.
