Differential repression of TLR responses by PPARg and LXRs

Project description:Transrepression mediated by PPARg and LXRs agonists (GW7845 and GW3965) in primary macrophages stimulated with LPS or poly I:C. Thioglycollate-elicited macrophages were isolated from mice by peritoneal lavage 3 days following peritoneal injection of 2.5 ml 3% thioglycollate (DIFCO). Cells were plated in RPMI medium 1640 and 10% fetal bovine serum, washed after 5 h the medium was removed and cells were fed with fresh medium containing 0.5% fetal bovine serum. Cells were treated with LPS (Sigma) a concentration of 100 ng/ml or poly I:C (100 ng/ml) in the absence or presence of receptor-specific agonists for PPARγ (GW7845) or LXR (GW3965) at 1 µM concentrations. Results suggest signal-dependent nuclear receptors transrepression pathways.

Expression profile of Human blood monocytes treated with bacterial lipids

Project description:Multiple studies have established associations between human gut bacteria and host physiology but determining the molecular mechanisms underlying these associations has been challenging1–3. Akkermansia muciniphila has been robustly associated with positive systemic effects on host metabolism, favorable outcomes to checkpoint blockade in cancer immunotherapy, and homeostatic immunity4–7. Here we report the identification of a lipid from A. muciniphila’s cell membrane that recapitulates the immunomodulatory activity of A. muciniphila in cell-based assays8. The isolated immunogen, a diacyl phosphatidylethanolamine with two branched chains (a15:0-i15:0 PE), was characterized through both spectroscopic analysis and chemical synthesis. The immunogenic activity of a15:0-i15:0 PE has a highly restricted structure-activity relationship, and its immune signaling requires an unexpected toll-like receptor 2/1 heterodimer9,10. Certain features of the phospholipid’s activity are noteworthy: it is significantly less potent than known natural and synthetic toll-like receptor 2 agonists; it preferentially induces some inflammatory cytokines but not others; and at low doses (1% of EC50) it resets activation thresholds and responses for immune signaling. Identifying both the molecule and an equipotent synthetic analog, its non-canonical toll-like receptor 2/1 signaling pathway, its immunomodulatory selectivity, and its low dose immunoregulatory effects provides a molecular mechanism for a model of A. muciniphila’s ability to set immunological tone and its varied roles in health and disease.

Toll-like receptor 2 activation depends on lipopeptide shedding by bacterial surfactants

Project description:Sepsis caused by Gram-positive bacterial pathogens is a major fatal disease but its molecular basis remains elusive. Toll-like receptor 2 (TLR2) has been implicated in the orchestration of inflammation and sepsis but its role appears to vary for different pathogen species and clones. Accordingly, Staphylococcus aureus clinical isolates differ substantially in their capacity to activate TLR2. Here we show that strong TLR2 stimulation depends on high-level production of phenol-soluble modulin (PSM) peptides in response to the global virulence activator Agr. PSMs are required for mobilizing lipoproteins, the TLR2 agonists, from the staphylococcal cytoplasmic membrane. Notably, the course of sepsis caused by PSM-deficient S. aureus is similar in wild-type and TLR2-deficient mice, but TLR2 is required for protection of mice against PSM-producing S. aureus. Thus, a crucial role of TLR2 depends on agonist release by bacterial surfactants. Modulation of this process may lead to new therapeutic strategies against Gram-positive infections.

Changes in transcription patterns in BoMac cells in response to PDD spirochetes

Project description:Papillomatous digital dermatitis (PDD) is a polymicrobial infection in soft tissue adjacent to the hoof and is the leading cause of lameness in dairy cattle. Treponema phagedenis-like (TPL) spirochetes are a constant feature of PDD lesions and are localized deep in infected tissue. Host-cell response mechanisms to TPL bacteria are poorly understood. To assess how bovine macrophages respond to cellular constituents of TPL spirochetes, changes in transcription were analyzed using serial analysis of gene expression (SAGE) and real time RT-PCR. This analysis revealed that bovine macrophages responded to stimulation with TPL-lysates by induction of several pro-apoptotic genes. Although several proinflammatory cytokines (eg. IL-6 and IL-8) are induced in treated macrophages, receptors and their accessory proteins for IL-1, IL-6, and IL-11 are either down regulated or unchanged. Surprisingly, IL-1beta is not induced and IL-18 is suppressed in treated macrophages. Two genes encoding proteins having negative effects on NFκB, IκB and Siva-1, are significantly induced in stimulated cells. Combined, these data suggest that the innate immune response of bovine macrophages exposed to TPL cellular constituents are impaired thereby enabling bacteria to resist clearance and induce lesion formation. Keywords: Bovine macrophage, transcription response, spirochete bacteria
