Monocyte-derived macrophages stimulated with the TLR8 agonist 3M-002 at 10 microM show a prominent activation of TLR-dependent genes as assessed b "Human Toll-like Receptor PCR array pathway" over time

ABSTRACT: We were interested in the effects of TLR8 triggering of human monocyte-derived macrophages. We observed a striking upregulation of those genes. This work was done in the context of examining the effects of TLR8 triggering for the activation of HIV.

Monocyte-derived macrophages stimulated with the TLR8 agonist 3M-002 at 10 microM show a prominent activation of TLR-dependent genes as assessed b "Human Toll-like Receptor PCR array pathway" over time

Project description:We were interested in the effects of TLR8 triggering of human monocyte-derived macrophages. We observed a striking upregulation of those genes. This work was done in the context of examining the effects of TLR8 triggering for the activation of HIV. We generated monocyte-derived macrophages (MDM) by initially isolating monocytes and subsequently culturing them in RPMI supplemented with human AB serum. MDM were stimulated for 18 h with the TLR8 agonist 3M-002, and subsequently harvested for extraction of total RNA. Total RNA was then used to quantify the TLR-dependent genes using a PCR array pathway.

U1 cells stimulated with the TLR8 agonist 3M-002 at 10 microM show a prominent activation of TLR-dependent genes as assessed by "Human toll-like Receptor PCR array pathway" over time

Project description:We investigated the effects of the TLR8 agonist 3M-002 on latently HIV infected U1 cells. We found a prominent upregulation of TLR-dependent genes. Notably, the TLR8 agonist resulted in a marked activation of HIV. We stimulated U1 cells for 6 or 10 hours with 3M-002 and subsequently harvested the cells, extracted total RNA. RNA was then used for quantifiying TLR-dependent gene upregulation using a commercial PCR array pathway

Reversal of human regulatory T cell suppression throgh TLR8 signaling

Project description:Analyses of gene alterations of human Treg cells treated with or without TLR8 ligand using the Illumina whole-genome Human HT-12 BeadChips. The study will provide important information for the molecular signature changes during the reversal of human Treg suppression mediated by activation of TLR8 signaling.

Quantitative Analysis of CXCL4 and TLR8 signaling crosstalk in human primary monocytes by RNA-Seq

Project description:To gain a comprehensive understanding of gene regulation in CXCL4 and TLR8 signaling crosstalk, we treated primary human blood monocytes with CXCL4 and TLR8 ssRNA ligand ORN8L for 6 h and performed transcriptomic analysis via RNA-seq. We observed that CXCL4 interacted with TLR8 ssRNA ligand and triggered inflammatory cytokine storm including IL6, IL12p40, TNF and IFNβ, and pro-fibrotic gene expression and activated NLRP3 inflammasome leading to interleukin-1β (IL-1β) secretion and pyroptosis in human blood monocytes.

RIPK3 negatively regulates the (CXCL4+TLR8)-induced IFN response while promoting NLRP3 inflammasome activation in human monocytes

Project description:To investigate the function of RIPK3 in regulation of IFN response and inflammatory response in human monocytes stimulated with CXCL4 and TLR8, We blocks (CXCL4 + TLR8)-induced pyroptosis and RIPK3 activation using necrosulfonamide (NSA, 5 µM) and GSK'872 (10 µM) and measure gene expression genome-wide with RNA-seq.
