Effects of LSD1 Inhibition on Macrophage Specialization into a Pro-Inflammatory Phenotype

نویسندگان

چکیده

Under the influence of many factors, such as cytokines or chemokines, macrophages specialize into two subpopulations: pro-inflammatory M1 (classical pathway) anti-inflammatory M2 (alternative pathway). Upon stimulation with bacterial ligand PAM3CSK4 and upon LPS (Lipopolysaccharide), TLR (toll-like receptors) 1/2 receptors TLR4, respectively, activate NFκB pathway, which leads to downregulation catalase expression through activity LSD1 HDAC1 complex. The main factor responsible for CAT repression is recruitment promoter site gene, resulting in pausing RNA polymerase. Inhibition SP2509 a decreased IL1b COX2, well some surface proteins, e.g., TLR2, despite presence LPS. iLSD1 prevents thereby inhibition macrophage polarization classic phenotype. In conclusion, regulation determines direction specialization.

TGF-β induces M2-like macrophage polarization via SNAIL-mediated suppression of a pro-inflammatory phenotype

Tumor-associated macrophages (TAMs) are a major component of leukocytic infiltrate in tumors, which facilitates tumor progression and promotes inflammation. TGF-β promotes the differentiation of non-activated macrophages into a TAM-like (M2-like) phenotype; however, the underlying mechanisms are not clear. In this study, we found that TGF-β induces a M2-like phenotype characterized by up-regula...

Anti-inflammatory Effects of PMX205 in Mouse Macrophage Periodontitis Model

Background: C5areceptor antagonistPMX205 is a synthetic hexapeptidecapable of blocking C5a-C5a receptor (C5aR) axis by simulating C5a active C-terminal amino acid residues. This hexapeptide presents good anti-inflammatory effects in a myriad inflammation models. The anti-inflammatory effect of PMX205 on periodontitis is yet to be fully fathomed. Objective: To examine the anti-inflammatory effec...

Effects of bee venom on the pro-inflammatory responses in RAW264.7 macrophage cell line.

The purpose of this study is to elucidate the molecular mechanism of anti-inflammatory effect of bee venom (BV), which has been used for the treatment of various inflammatory diseases in oriental medicine. With this aim, we examined the effects of BV on the nitric oxide (NO) production by lipopolysaccharide (LPS) or sodium nitroprusside in RAW264.7 macrophages. We further investigated the effec...
