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

ABSTRACT: 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.

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.

CXCL4 induces a unique transcriptome in monocyte-derived macrophages

Project description:Human blood monocytes were differentiated over six days with either 100 ng/ml M-CSF or 1 umol/l CXCL4 In atherosclerotic arteries, blood monocytes differentiate to macrophages in the presence of growth factors like macrophage colony-stimulation factor (MCSF) and chemokines like platelet factor 4 (CXCL4). To compare the gene expression signature of CXCL4-induced macrophages with MCSF-induced macrophages or macrophages polarized with IFN-Î³/LPS (M1) or IL-4 (M2), we cultured primary human peripheral blood monocytes for six days. mRNA expression was measured by Affymetrix gene chips and differences were analyzed by Local Pooled Error test, Profile of Complex Functionality and Gene Set Enrichment Analysis. 375 genes were differentially expressed between MCSF- and CXCL4-induced macrophages, 206 of them overexpressed in CXCL4 macrophages coding for genes implicated in the inflammatory/immune response, antigen processing/presentation, and lipid metabolism. CXCL4-induced macrophages overexpressed some M1 and M2 genes and the corresponding cytokines at the protein level, however, their transcriptome clustered with neither M1 nor M2 transcriptomes. They almost completely lost the ability to phagocytose zymosan beads. Genes linked to atherosclerosis were not consistently up- or downregulated. Scavenger receptors showed lower and cholesterol efflux transporters higher expression in CXCL4- than MCSF-induced macrophages, resulting in lower LDL content. We conclude that CXCL4 induces a unique macrophage transcriptome distinct from known macrophage types, defining a new macrophage differentiation that we propose to call M4. two MCSF samples and two CXCL4 samples

Ubiquitylation of RIPK3 beyond-the-RHIM limits RIPK3 activity and cell death

Project description:Pathogen recognition receptors and TNF superfamily members engage Receptor Interacting Serine/threonine Kinase-3 (RIPK3) to activate programmed cell death, including MLKL-mediated necroptosis and caspase-8-dependent apoptosis. However, the post-translational control of RIPK3 signalling is not fully understood. Using mass-spectrometry, we identified a novel ubiquitylation site on murine RIPK3 beyond the RIP homotypic interaction motif (RHIM) on K469. Complementation of RIPK3-deficient cells with a Ripk3K469R mutant demonstrated that the decoration of RIPK3 K469 by ubiquitin limits both RIPK3-mediated caspase-8 activation and apoptotic killing, in addition to RIPK3 autophosphorylation and MLKL-mediated necroptosis. Unexpectedly, the overall ubiquitylation of mutant RIPK3K469R was enhanced, which largely resulted from additional RIPK3 ubiquitylation on K359. Loss of RIPK3 K359 ubiquitylation reduced RIPK3K469R hyper-ubiquitylation and limited the ability of Ripk3K469R/K469R to trigger enhanced killing. Ripk3K469R/K469R mice challenged with Salmonella displayed increased bacterial loads in the spleen and liver, with reduced IFN serum levels. Therefore, RIPK3 K469 ubiquitylation can function to prevent RIPK3 ubiquitylation on alternate lysine residues, which otherwise promote RIPK3 oligomerization and consequent cell death signalling.
