Previous studies showed that mouse spleen cells produced IL-12, TNF-alpha, and IFN-gamma when stimulated with phagocytosable-size chitin particles (N-acetyl-D-glucosamine polymers).
|
16 |
9278339

|
The treatments with soluble mannan or with cytochalasin D, in sharp contrast, did not inhibit LPS-induced IL-12/IFN-gamma production or exogenous IL-12-induced IFN-gamma production.
|
18 |
9278339
|
Finally, spleen cells from C3H/HeJ mice also showed comparable levels of IL-12/TNF-alpha/IFN-gamma production when induced by 1 to 10 microm chitin particles.
|

BmDC cultured under various conditions (granulocyte-macrophage CSF (GM-CSF) or GM-CSF plus IL-4 alone or in combination with Flt3 ligand, TNF-alpha, LPS, or CD40 ligand (CD40L)) were analyzed morphologically, phenotypically, and functionally and were tested for their ability to promote prophylactic and/or therapeutic antitumor immunity.
|
22 |
9886383

We investigated the composition of proteasomes of DC derived from human peripheral blood monocytes before and after stimulation by CD40L, LPS, or proinflammatory cytokines (TNF-alpha + IL-6 + IL-1beta).
|
28 |

|
Immunoprecipitation of proteasomes and analysis on two-dimensional gels revealed that during maturation the inducible proteasome subunits LMP2, LMP7, and MECL-1 are up-regulated and that the neosynthesis of proteasomes is switched exclusively to the production of immunoproteasomes containing these subunits.

Ad infection (MOI 200) of BMDC induced significant increases in IL 12 p40 protein in culture supernatants (6 x that of uninfected BMDC and similar to that observed with addition of LPS and CD40 crosslinking antibody).
|
31 |
10918477
|
Consistent with DC activation, FACs analysis showed BMDC infected with Ad vectors up-regulated the surface expression of B7-2, ICAM-1 and MHC II.
|

|
Immature DC (DCimm) capture, process, and present Ags to CD4(+) lymphocytes, which reciprocally activate DCimm through CD40, and the resulting mature DC (DCmat) loose phagocytic capacity, but acquire the ability to efficiently stimulate CD8(+) lymphocytes.
|
37 |
11290810
|
Recombinant vaccinia viruses (rVV) provide a rapid, easy, and efficient method to introduce Ags into DC, but we observed that rVV infection of DCimm results in blockade of DC maturation in response to all activation signals, including CD40L, monocyte-conditioned medium, LPS, TNF-alpha, and poly(I:C), and failure to induce a CD8(+) response.
|
38 |
11290810
|
These results demonstrate that despite rVV interference with DCimm maturation, a single targeting vector can deliver Ags to DCmat for the effective simultaneous stimulation of both CD4(+) and CD8(+) cells.

Characteristic immunophenotypic and functional DC maturation induced by standard monocyte conditioned medium (MCM) was compared to the activation induced by a panel of stimuli including soluble CD40L, LPS, Poly I:C, PGE(2)/TNFalpha, and a cocktail mixture of PGE(2)/TNFalpha/IL-1beta/IL-6.
|
41 |
11792391
|
Immunophenotypic analysis confirmed that all stimuli induced stable up-regulation of CD25, CD40, CD80, CD83, CD86, HLA-DR, DC-LAMP (CD208), and DEC-205 (CD205).

In natural immune responses CD4+ T helper (Th) cells, reactive with peptide antigens presented by major histocompatibility complex (MHC) class II molecules on dendritic cells (DC), can drive the maturation of DC that is required for induction of CD8+ cytolytic T-lymphocyte (CTL) immunity.
|
63 |
12445291
|
Proper induction, expansion and maintenance of CTL responses are achieved through delicate interactions between CD4+ T cells, DC and CD8+ T cells involving several ligand-receptor pairs.
|
64 |
12445291
|
Th cells to a large extent operate through up-regulation of CD40L, which then interacts with CD40 on DC to cause DC maturation.
|
65 |
12445291
|
Subsequent CTL induction by activated DC requires CD80/CD86 on the DC to interact with the CD28 costimulatory receptor on CD8+ T cells.
|
66 |
12445291
|
Alternative molecular triggers of DC activation that can support induction of powerful CTL responses include agonistic anti-CD40 antibody or ligands of Toll-like receptors (TLR) such as LPS (TLR4 ligand) or oligodeoxynucleotides containing CpG-motifs (TLR9 ligand).

|
The addition of TNF-alpha, polyriboinosinic polyribocytidylic acid (Poly(I:C)) and LPS to autologous DCs resulted in the emergence of only a small percentage of CD83+ DCs, IFN-alpha having no demonstrable effect.
|
69 |
12519390
|
Only the addition of Poly(I:C) to DCs resulted in modestly increased specific cytotoxicity to B-CLL targets, IFN-alpha and LPS having no effect.
|
70 |
12547595
|
Upon stimulation by infectious agent products, dendritic cells (DC) become activated, express high levels of class I and class II antigens, CD80, CD86 and CD83 and migrate to secondary lymphoid organs where they can prime naive CD4-helper and CD8-cytotoxic T-cells.
|
71 |
12547595
|
Cognate CD4(+) T-cell help mediated by CD40L along with DC stimulation with another T-cell effector molecule, termed lymphocyte activated gene-3 (LAG-3 or CD223, a ligand for MHC class II) have been shown to induce this maturation process.
|
72 |
12547595
|
Both CD40L and LAG-3 have been used as vaccine adjuvants to induce CTL and CD4 Th1 responses.
|
73 |
12547595
|
LAG-3Ig, unlike CD40L, induced an inflammatory signal in terms of IL-8 and MIP-1alpha/CCL3 production and, in contrast to LPS, induced production of chemokines (MDC/CCL22 and TARC/CCL17) known to direct the migration of maturing DC to lymph nodes.
|
74 |
12547595
|
In LAG-3-matured DC, surface expression of CCR5 (a receptor for MIP-1alpha/CCL3) was down-regulated and CCR7 (a receptor for MIP-3beta and SLC) was up-regulated.
|
75 |
12547595
|
However, LAG-3-matured, but not LPS- or CD40L-matured DC retained their capacity to migrate in chemotaxis chambers and to respond to MIP-1alpha.

LPS, MPL and CpG DNA, which activate cells of the innate immune system.

We show that E. coli LPS-pulsed MDDC released Th1-biasing cytokines - consisting of high levels of IL-12 p70, IFN-gamma-inducible protein 10 (IP-10) - but also TNF-alpha, IL-10, IL-6 and IL-1beta.
|
78 |
14579266
|
In contrast, no IL-12 p70 or IP-10, and lower levels of TNF-alpha and IL-10 were induced by P. gingivalis LPS.
|
79 |
14579266
|
These differences were sustained at LPS doses that yielded nearly equivalent maturation of MDDC; moreover the T cell response was consistent: E. coli LPS-pulsed MDDC induced higher T cell proliferation, and T cells released more IFN-gamma and IL-2, but less IL-5 than T cells co-cultured with P. gingivalis LPS pulsed-MDDC.

Distinct modulatory effects of LPS and CpG on IL-18-dependent IFN-gamma synthesis.

81 |
14734758
|
C3H/HeN mice pretreated with LPS for 2 days generated 5-fold less circulating IL-12 p70 and IFN-gamma in response to subsequent LPS challenge than did challenged control mice.
|
82 |
14734758
|
In contrast, CpG-pretreated mice produced 10-fold more circulating IFN-gamma without similar changes in IL-12 p70 levels, but with 10-fold increases in serum IL-18 relative to LPS-challenged control or endotoxin-tolerant mice.
|
83 |
14734758
|
Finally, combined pretreatment of mice with LPS and CpG suppressed the production of circulating IFN-gamma, IL-12 p70, and IL-18 after subsequent LPS challenge.
|
84 |
14734758
|
We conclude that CpG potentiates innate IFN-gamma production from NK cells by increasing IL-18 availability, but that the suppressive effects of LPS on innate cellular immunity dominate during combined LPS and CpG pretreatment.

A Toll-like receptor 2 ligand stimulates Th2 responses in vivo, via induction of extracellular signal-regulated kinase mitogen-activated protein kinase and c-Fos in dendritic cells.
|
97 |
15067049
|
Thus, Escherichia coli LPS (TLR-4 stimulus), activates DCs to produce abundant IL-12(p70), but little IL-10, and stimulates Th1 and Tc1 responses.
|
98 |
15067049
|
In contrast, Pam-3-cys (TLR-2 stimulus) elicits less IL-12(p70), but abundant IL-10, and favors Th2 and T cytotoxic 2 (Tc2) responses.
|
99 |
15067049
|
Thus, Pam-3-cys induces enhanced extracellular signal-regulated kinase signaling, compared with LPS, resulting in suppressed IL-12(p70) and enhanced IL-10 production, as well as enhanced induction of the transcription factor, c-Fos.
|
100 |
15067049

Interestingly, DCs from c-fos(-/-) mice produce more IL-12(p70), but less IL-10, compared with control DCs.

|
In this study, we demonstrate that pretreatment of monocytes with human HSP60 results in a suppression of TNF-alpha production on restimulation with HSP60.
|
107 |
15214052
|
Furthermore, desensitization with HSP60 inhibits TNF-alpha expression in these cells in response to LPS stimulation, thereby inducing "cross-tolerance".
|
108 |
15214052
|
In contrast to TNF-alpha suppression, IL-1beta expression was augmented in HSP60-pretreated monocytes on restimulation, while being suppressed in THP-1 cells.
|
109 |
15214052
|
Addition of an anti-IL-10 neutralizing antibody had no significant effect on HSP60- or LPS-induced tolerance.HSP60 priming of monocytes also results in significant down-regulation of HLA-DR, CD86 and Toll-like receptor 4 expression, but minimally up-regulates CD80 expression, similar to that previously reported with LPS.
|
110 |
15214052
|
By identifying a previously unrecognized "tolerizing" effect of extended exposure to autologous HSP60 on the innate immune system, as opposed to its recently identified pro-inflammatory stimulatory capacity, this study highlights a further level of complexity of our understanding of the biological activities of HSP.

|
Zymosan, poly(I:C) and CpG DNA, which signal through TLR2/6, 3 and 9, respectively, were found to strongly induce the production of IgG2a antibodies, whereas R-848 (TLR7) and LPS (TLR4) did so much more weakly.
|
112 |
15550117
|
In contrast, LPS, poly(I:C) and CpG DNA, but not zymosan, induced functional CD8+ T-cell responses against OVA; peptidoglycan (TLR2/?)
|
113 |
15550117
|
In addition, our results demonstrate that the ability of TLR stimuli to initiate CD8+ T-cell responses against soluble protein antigens is largely dependent on the IFN-alpha/beta signalling pathway.
|

|
Exposure of a LC-like cell line to ATPgammaS in the presence of LPS and GM-CSF augmented the induction of I-A, CD80, CD86, IL-1beta, and IL-12 p40 while inhibiting the expression of IL-10, suggesting that the immunostimulatory activities of purinergic agonists in the skin are mediated at least in part by P2Rs on APCs.

However, both wild type meningococcal LOS and KDO(2)-lipid A, significantly up-regulated CD80, CD83 and CD86 and released significantly higher amounts of IL-12p70, IL-6, IL-10, TNFalpha, MCP-1, IP-10 and RANTES.
|
117 |
16246469
|
Further, DCs stimulated with wild type or KDO(2)-lipid A but not meningococcal lipid A or penta-acylated KDO(2)-lipid A stimulated naïve allogeneic CD4+ T cells to secrete enhanced levels of IFN-gamma, relative to T cells primed with immature DCs.
|
118 |
16246469
|
In contrast to Escherichia coli LPS, IL-5 production was enhanced or maintained in CD4+ T-cells stimulated with MDDC exposed to wild-type meningococcal LOS and KDO(2)-lipid A.
|
119 |
16246469
|
These data suggest that KDO linked to a fully acylated meningococcal lipid A is required for meningococcal endotoxin's immunostimulatory activity of human MDDC via TLR4/MD-2 and that different endotoxin structures influence Th responses mediated by MDDC.

In culture medium with ripe DC the levels of such cytokines as IL-1b, IL-6, IL-12, IFN-gamma, TNF-alpha significantly increased and the production of IL-4 decreased.
|
123 |
16279537
|
The content of IL-2 and IL-10 remained unchanged.

In contrast to most LPS, highly purified Ft LVS LPS (10 microg/ml) was found to be only minimally stimulatory in primary murine macrophages and in HEK293T cells transiently transfected with TLR4/MD-2/CD14, whereas live Ft LVS bacteria were highly stimulatory for macrophages and TLR2-expressing HEK293T cells.
|
126 |
16895974
|
Using cells derived from TLR2-deficient mice and in vitro transfection assays, we demonstrated that this response was mediated by TLR2 and did not require the LPS-binding protein.
|
127 |
16895974
|
F. tularensis appeared to activate TLR2/TLR1 and TLR2/TLR6 heterodimers.
|
128 |
16895974
|
IL-1beta secretion, a reflection of caspase-1 activation, was induced by live but not heat-killed F. tularensis, despite the fact that both forms of the bacterium equally induced the IL-1beta transcript.
|
129 |

|
Thimerosal, in a concentration-dependent manner, inhibited the secretion of LPS-induced proinflammatory cytokines TNF-alpha, IL-6, and IL-12p70 from human monocyte-derived DC.
|
130 |
17079650
|
These thimerosal-exposed DC induced increased TH2 (IL-5 and IL-13) and decreased TH1 (IFN-gamma) cytokine secretion from the T cells in the absence of additional thimerosal added to the coculture.
|
131 |
17079650
|
Thimerosal exposure of DC led to the depletion of intracellular glutathione (GSH), and addition of exogenous GSH to DC abolished the TH2-promoting effect of thimerosal-treated DC, restoring secretion of TNF-alpha, IL-6, and IL-12p70 by DC and IFN-gamma secretion by T cells.
|
132 |
17499399

Gene clusters which encode capsular polysaccharide (type I O-PS) and LPS (type II O-PS), both of which play roles in virulence, have previously been identified.
|
134 |
17698917
|
As expected, TLR agonists, such as LPS (TLR4) and fibroblast-stimulating lipopeptide-1 (FSL-1; TLR2), induced macrophage activation and increased macrophage killing of phase II C. burnetii in vitro.
|
135 |
17698917
|
Securinine, a gamma-aminobutyric acid type A receptor antagonist, was found to induce TLR-independent macrophage activation in vitro, leading to IL-8 secretion, L-selectin down-regulation, and CD11b and MHC Class II antigen up-regulation.
|
136 |
18354154
|
In general, the uptake of Leishmania parasites alone can trigger relatively weak and transient DC activation; however, the intracellular parasites (amastigotes) are capable of down-modulating LPS/IFN-gamma-stimulated DC activation via multiple mechanisms.
|
137 |
18354157
|
Pulsing DCs with a lysate of L. major did not affect DC maturation with TNF-alpha or LPS+anti-CD40.
|
138 |
18354157
|
When the expression of different Notch ligands on DCs was analyzed, we found increased expression of Th2-promoting Jagged2 in TNF-DCs, whereas LPS+CD40-DCs up-regulated the Th1-inducing Delta4 and Jagged1 molecules.
|

|
The function of exosomes in immunity was detected through block test after blocking some molecules (CD11a, CD11b, CD11c, CD54, MFG-E8 and CD83).
|
140 |
18549647
|
The exosomes derived from mDC induced with different cytokines (LPS, TNF-alpha, CpG, CD40L) were no significant difference in concentrations but were different in effect.
|
141 |
18549647
|
The immunity function of exosomes depended on CD11a, CD11b, CD11c, CD54, MFG-E8 and CD83 molecules, the effect of priming T cells is reduced when these molecules were blocked.
|
142 |
18549647
|
Confocal microscopy and FACS assay showed that blocking CD11a and CD54 could inhibit exosome-targeted DC and DC-embedded exosomes.
|
143 |

|
Considering the importance of CD14 - TLR2/TLR4 interactions in macrophage signalling, we determined the polymorphism of TLR2 and TLR4 genes as well as macrophage expression of TLR2 for the volunteers with and without skin reactivity to PPD.
|
144 |
19056540
|
A significant increase in CD14 density was observed on macrophages stimulated with PPD and LPS but not with live BCG bacilli.
|
145 |
19056540
|
However, we could see no association between the polymorphisms of TLR4 (Asp299Gly and Thr399Ile) and TLR2 genes (Arg753Gln and Arg677Trp) and skin responses to PPD.
|
146 |
19578865
|
We investigated the effect of different toll like receptor (TLR) agonists including LPS (TLR4 agonist), polyinosinic acid-polycytidylic acid (PIC, TLR3 agonist), CpG oligonucleotide (TLR9 agonist), and imiquimod (TLR7 agonist) on human monocyte-derived dendritic cells (mdDCs) loading of human papillomavirus (HPV) type 11 E7 epitope.
|
147 |
19578865
|
This was characterized by an enhanced expression of CD40, CD80, CD86, CD83 and HLA-DR, and a high level of IL-12 production.
|
148 |
19580785
|
Human monocyte-derived immature or LPS- and cytokine-matured DCs were exposed to ambient or 40 mmHg increased pressure for 12h, then assessed for expression of CD80, CD86, CD40, MHC-I/II, and inflammatory cytokine production.
|
149 |
20176741
|
Day 3 ROS(lo) DCs were highly responsive to TLR stimuli such as LPS and zymosan by rapid upregulation of CD80, CD86, and MHC class II, in contrast to the low response of day 6 ROS(hi) DCs.
|
150 |
20176741
|
ROS(hi) DCs could not initiate and sustain a significant level of NF-kappaB phosphorylation in response to LPS and zymosan, although demonstrating hyperactivation of p38 MAPK by LPS, in a fashion disparate to ROS(lo) DCs.
|
151 |
20817880
|
IRAK-M(-/-) DCs increase the proliferation and activation of Ag-specific T cells, and a single vaccination with Ag-pulsed, LPS-matured IRAK-M(-/-) DCs eliminates established tumors and prolongs the survival of EG7 or B16.f10 tumor-bearing mice, without discernible induction of autoimmune disease.

|
The soluble L. donovani Ag stimulated PBMCs of cured/exposed and Leishmania patients to produce a mixed Thl/Th2-type cytokine profile, whereas rLelF-2 stimulated the production of IFN-γ, IL-12, and TNF-α but not IL-4 or IL-10.
|
157 |
22079980
|
Further, rLelF-2 downregulated LPS-induced IL-10 as well as soluble L. donovani Ag-induced IL-4 production by Leishmania patient PBMCs.
|
158 |
22079980
|
The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFN-γ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
|
159 |
22365841
|
Murine bone marrow-derived DCs were cultured and matured with LPS, IL-4 and IFN-γ (type-1 polarized DCs), and with LPS alone (non-polarized DCs).
|
160 |
22415304
|
Rv0577 recognizes Toll-like receptor 2 (TLR2) and functionally induces DC maturation by augmenting the expression of cell surface molecules (CD80, CD86, and MHC class I and II) and proinflammatory cytokine production (TNF-α, IL-1β, IL-6, and IL-12p70) in DCs on MyD88-dependent signaling, mitogen-activated protein kinases, and nuclear factor κB signaling pathways.
|
161 |
22415304
|
In addition, Rv0577-treated DCs activated naive T cells, effectively polarized CD4(+) and CD8(+) T cells to secrete IFN-γ and IL-2, and induced T-cell proliferation, indicating that this protein possibly contributes to Th1-polarization of the immune response.
|
162 |
22415304
|
More important, unlike LPS, Rv0577-treated DCs specifically induced the proliferation of memory CD4(+)/CD8(+)CD44(high)CD62L(low) T cells in the spleen of M. tuberculosis-infected mice in a TLR2-dependent manner.
|
163 |
23732326
|
The results showed that GPSL could significantly enhance T and B lymphocytes proliferation singly or synergistically with PHA and LPS and the efficacy were superior to those of gypenosides (GPS) and blank liposome (BL) at most of concentrations.
|
164 |
23781340
|
In this study, IFN-gamma treatment of bone marrow-derived DC, followed by incubation with the TLR2, TLR4, or TLR9 agonists, enhanced DC activation compared to TLR ligation alone.
|
165 |
23781340
|
Most notably, the upregulation of CD40 with LPS stimulation and CD86 with CpG stimulation was observed in in vitro cultures.
|
166 |
23781340
|
Similarly, IFN-gamma coinjected with TLR ligands was able to promote DC activation in vivo, with DCs migrating from the site of immunization to the popliteal lymph nodes demonstrating increased expression of CD80 and CD86.
|
167 |
23940691
|
Its response to synthetic TLR ligands (R848: TLR7/8, LPS: TLR4) was on a comparable threshold to the more time consuming peripheral blood mononuclear cell (PBMC) based assay.

|
Urease, BabA and SabA in the adhesion-step, PGN and LPS in the immune evasion-step, and CagA, VacA and Tipα in the mucosal damage-step were documented to play an important role in step-specific pathogenicity of H. pylori infection.
|
169 |
24076409
|
There is evidence further supporting a role of potentially functional polymorphisms of host genes directly responding to these pathogenic step-specific virulence factors in the susceptibility of gastric carcinogenesis, especially for urease-interacting HLA class II genes, BabA-interacting MUC1, PGN-interacting NOD1, LPS-interacting TLR4, and CagA-interacting PTPN11 and CDH1.

|
Moreover, rLdTPR reasonably stimulated PBMCs of cured Leishmania patients to produce IFNγ, IL-12, and TNF-α but not IL-4 or IL-10.
|
173 |
24370734
|
On the other hand, the protein downregulated LPS-induced IL-10 as well as soluble L. donovani antigen-induced IL-4 production in PBMCs of Leishmania patients.
|
174 |
24370734
|
The efficacy was supported by the increased inducible NO synthase mRNA transcript and Th1-type cytokines IFNγ, IL-12, and TNF-α and downregulation of IL-4, IL-10, and TGF-β.
|
175 |
24846569
|
Pretreatment with WapA-GST also increased LPS-induced proinflammatory cytokine production by DCs, including IL-12, IL-6 and TNF-α.
|
176 |
24846569
|
Furthermore, expression of the DC maturation markers CD80/86, CD40 and MHC II was also increased by WapA pretreatment.
|
177 |
25211769
|
CD4-positive T cells from mice primed with OVA-NPs produced substantial levels of IL-21 and IL-4, comparable to those from OVA-alum group.
|
178 |
25211769
|
Moreover, when OVA-NPs-primed, but not OVA-alum-primed, B cells were cultured in the presence of anti-CD40 monoclonal antibody, IL-4, and IL-21, or LPS plus TGF-β in vitro, OVA-specific IgG1 or IgG2b antibody responses were elicited, suggesting that immunization with OVA-NPs modulates B cells to generate IgG1 and IgG2b responses.

|
Secretion of IL-6, RANTES (CCL5) and IP-10 (CXCL10) were assessed by ELISA.
|
180 |
25540284
|
MPLA alone was a weak stimulator of myeloid differentiation primary response protein 88-dependent IL-6 and did not induce TIR-domain-containing adapter-inducing IFN-β (TRIF)-dependent chemokine responses.
|
181 |
25540284
|
MPLA significantly reduced LPS-mediated IL-6 production.
|
182 |
25540284
|
This inhibitory effect was also conferred for the TRIF-dependent chemokines RANTES and IP-10.
|

We recently described the induction of noncanonical IL-1β processing via caspase-8 recruited to ripoptosome signaling platforms in myeloid leukocytes.
|
184 |
26100631
|
Here, we demonstrate that activated NLRP3·ASC inflammasomes recruit caspase-8 to drive IL-1β processing in murine bone marrow-derived dendritic cells (BMDC) independent of caspase-1 and -11.
|
185 |
26100631
|
Sustained stimulation (>2 h) of LPS-primed caspase-1-deficient (Casp1/11(-/-)) BMDC with the canonical NLRP3 inflammasome agonist nigericin results in release of bioactive IL-1β in conjunction with robust caspase-8 activation.
|
186 |
26100631
|
This IL-1β processing and caspase-8 activation do not proceed in Nlrp3(-/-) or Asc(-/-) BMDC and are suppressed by pharmacological inhibition of caspase-8, indicating that caspase-8 can act as a direct IL-1β-converting enzyme during NLRP3 inflammasome activation.
|
187 |
26100631
|
Biochemical analyses of WT and Casp1/11(-/-) BMDC indicated that caspase-8 is proteolytically processed within detergent-insoluble ASC-enriched protein complexes prior to extracellular export during nigericin treatment.
|
188 |
26100631
|
Although nigericin-stimulated caspase-1 activation and activity are only modestly attenuated in caspase-8-deficient (Casp8(-/-)Rip3(-/-)) BMDC, these cells do not exhibit the rapid loss of viability of WT cells.
|
189 |
26100631
|
These results support a contribution of caspase-8 to both IL-1β production and regulated death signaling via NLRP3 inflammasomes.
|
190 |
26100631
|
In the absence of caspase-1, NLRP3 inflammasomes directly utilize caspase-8 as both a pro-apoptotic initiator and major IL-1β-converting protease.
|
191 |
26100631
|
In the presence of caspase-1, caspase-8 acts as a positive modulator of the NLRP3-dependent caspase-1 signaling cascades that drive both IL-1β production and pyroptotic death.
|
192 |

|
The mRNA expression of RbKSPI significantly increased in blood cells upon stimulation with two strains of bacteria (Edwardsiella tarda and Streptococcus iniae) and two pathogen-associated molecular patterns (PAMPs; LPS and poly I:C).
|
193 |
26301593
|
However, IL-1β secretion did require NLRP3 and caspase-1 activity.
|
194 |
26301593

Aging affects the responsiveness of rat peritoneal macrophages to GM-CSF and IL-4.
|
196 |
26463212
|
Therefore, resident and thioglycollate-elicited peritoneal macrophages from young (3-month-old) and aged (18-19-month-old) rats were tested for phagocytic capacity and ability to secrete inflammatory mediators following in vitro stimulation with LPS and GM-CSF, and IL-4, prototypic stimulators for classically (M1) and alternatively activated (M2) macrophages, respectively.
|
197 |
26463212
|
Aging increased the frequency of monocyte-derived (CCR7+ CD68+) and the most mature (CD163+ CD68+) macrophages within resident and thioglycollate-elicited peritoneal macrophages, respectively.
|
198 |
26463212
|
The ability to phagocyte zymosan of none of these two cell subsets was affected by either LPS and GM-CSF or IL-4.
|
199 |
26463212
|
The upregulated production of IL-1β, IL-6 and IL-10 and downregulated that of TGF-β was observed in response to LPS in resident and thioglycollate-elicited macrophages from rats of both ages.
|
200 |
26463212
|
GM-CSF elevated production of IL-1β and IL-6 in resident macrophages from aged rats and in thioglycollate-elicited macrophages from young rats.
|
201 |
26463212
|
Unexpectedly, IL-4 augmented production of proinflammatory mediators, IL-1β and IL-6, in resident macrophages from aged rats.
|
202 |
26463212
|
In conclusion, our study showed that aging diminished GM-CSF-triggered polarization of elicited macrophages and caused paradoxical IL-4-driven polarization of resident macrophages toward proinflammatory M1 phenotype.
