Cell Signaling Technology Inc stat6 (rabbit ab) antibody

Bone marrow derived macrophages (BMDM, purity >95%) were generated and splenic B cells (purity > 90%) isolated from mice that do express <t>STAT6</t> only under control of the LysMCre promoter (Mac-STAT6), STAT6 knockout mice (STAT6ko) and BALB/c wild-type (WT) controls. A) Western blot of unstimulated (w/o) and IL-4-stimulated BMDM and B cell lysates of the indicated genotypes for phosphorylated STAT6 (pSTAT6), total STAT6 and β-actin as loading control. Western blot is representative for three to five mice per genotype from two independent experiments. B) qRT-PCR of BMDM from either Mac-STAT6, STAT6ko or WT mice stimulated with 20 ng/ml IL-4 for 48 hrs. Bars show mean expression + SEM of Arg1 , Retnla and Pdcd1lg2 normalized on Hprt of three to four mice per genotype out of two experiments.

In psoriasis patients, inflammatory factors TGF-β and IL-23 stimulate the expression of HIF-1α, which recruits P300 to the miR-210 promoter region and increases the H3ac levels on miR-210 promoters, thus leading to the upregulation of miR-210 expression. miR-210 represses STAT6 and LYN expression through binding the 3′-UTRs of STAT6 and LYN mRNA, which promotes Th1/Th17 cell differentiation and inhibits Th2 cell differentiation in psoriasis. Moreover, miR-210 overexpression also enhances the proliferation and chemokine secretion of keratinocytes, which increases the recruitment of activated T cells in skin lesions. Together, the effects of the increased miR-210 in CD4+ T cells and keratinocytes contribute to the formation of psoriatic skin lesions.
