WebSince STAT6-deficient macrophages exhibit higher reliance on fatty acid metabolism, we postulated that this might represent a compensatory response to decreased glycolytic flux. Indeed, as shown in Figure 3E, both basal and IL-4-stimulated rates of glucose uptake were reduced by ~45% and ~70%, respectively, in STAT6 null macrophages (Figure 3E ... WebApr 1, 2024 · C. Use of genetics to aid in macrophage activation studies. Mutations in Akt1 and Klf4 cause a ‘switch’ to M(LPS) and M(IFNγ) associated gene expression while mutations in Akt2 and Klf6 show the reverse phenotype. Mutations in Stat6, Ppard, Pparg, Irf4 and IRF5 depletion are involved in the maintenance and/or amplitude of activation.
WebMay 30, 2024 · Signal transducer and activator of transcription (STAT) factors are important regulators of macrophage polarization. IFN-γ–activated STAT1 has been linked to M1 polarization, while STAT6 and STAT3, activated by IL-4/IL-13 and IL-10, respectively, have been linked to M2 polarization ( 13 ).

WebFeb 25, 2024 · Gene regulatory network models revealed E2F1, MYC, PPARγ and STAT6 to be the major players in the distinct signatures of these polarization events. WebApr 20, 2016 · The polarization of M2 macrophage is mediated by IL-4-dependent activation of STAT6, which leads to the expression of Fizz1, Ym-1 and Arg1 in macrophages 34. These results provided a molecular ...
STAT6-mediated signaling pathway is required for the development of T-helper type 2 (Th2) cells and Th2 immune response. Expression of Th2 cytokines, including IL-4, IL-13, and IL-5, was reduced in STAT6 - / - mice. STAT 6 protein is crucial in IL4 mediated biological responses. It was found that STAT6 induce the expression of BCL2L1/BCL-X(L), which is responsible for the anti-apoptotic activity of IL4. IL-4 stimulates the phosphorylation of IL-4 receptor, which recruits cyto…
WebFeb 26, 2024 · Double immunofluorescence staining for phospho-STAT6 and Mac3 in peritoneal macrophages showed that phospho-STAT6 expression was observed in Mac3-positive macrophages from WT mice and enhances in a time-dependent manner and peaks 72 h after zymosan injection (Figure 1 A). Phospho-STAT6 staining was shown to localize … readings 4 eso pdfWebApr 11, 2024 · IL(Interleukin)-4 is the main macrophage M2-type activator and induces an anti-inflammatory phenotype called alternative activation. The IL-4 signaling pathway involves the activation of STAT (Signal Transducer and Activator of Transcription)-6 and members of the MAPK (Mitogen-activated protein kinase) family. In primary-bone-marrow … readings 4 youTo test whether Stat6 acetylation plays a role during macrophage M2 polarization, we stimulated murine macrophages with IL-4 and then immunoprecipitated Stat6 to examine its acetylation status. IL-4 stimulation induced the substantial acetylation of lysine residues in Stat6 in macrophages (Fig. 1a). Previous … See more To confirm that Stat6 acetylation occurs at Lys383, we generated a polyclonal antibody against Lys383-acetylated Stat6 (Fig. 2a, b). Indeed, … See more Since Stat6 acetylation is strongly induced in macrophages upon IL-4 stimulation, we hypothesized that IL-4-regulated genes modulate CBP-mediated Stat6 acetylation. Therefore, we … See more To study the in vivo function of Trim24-modulated Stat6 acetylation, we generated conditional knockout (KO) mice in which Trim24 was deleted specifically in myeloid cells (termed … See more To investigate how Trim24 regulates the association of CBP with Stat6, the plasmids encoding full-length Trim24 and functional domains-deleted Trim24 were generated (Fig. 4a). … See more how to switch server boost discordWebSep 25, 2024 · Stat6 is acetylated at Lys383. a–c Immunoblot analysis of the lysine acetylation of Stat6 in primary murine macrophages (a) or 293T cells transfected with the indicated expression vectors (b ... how to switch seats in fivemWebMar 3, 2024 · KFs could trigger p-STAT6 activation of M0 cells with upregulation of M2-related genes, and importantly, TGF-β expression.
