概括
急性泛性脱血性松病 (AGEP) 是一种药物诱导的泛性松性松病 (GPP) 的变体. 这两种情况都有共同的分子特征,表明IL-36抑制是相关的 pustulosis 谱系疾病的潜在治疗方法.
科学领域:
- 皮肤病学 皮肤病学
- 免疫学 免疫学 免疫学
- 基因组学就是基因组学.
背景情况:
- 鉴于它们的临床表现重叠,区分泛性性牛皮 (GPP) 和急性泛性脱血性牛皮 (AGEP) 具有挑战性.
- 之前的研究已经强调了需要分子表征来区分这些条件.
研究的目的:
- 定义GPP和AGEP的独特分子和本病学特征.
- 调查GPP,AGEP和其他性和非性皮肤疾病之间的关系.
主要方法:
- 在125名患者的皮肤活检样本上进行了RNA测序和组织病理学分析.
- 患者包括那些患有AGEP,GPP,棕植物 pustulosis (PPP),斑块性牛皮 (PSO),非状皮肤不良药物反应 (ADRs) 和健康对照的人.
- 分析了不同的基因表达和免疫细胞组成.
主要成果:
- AGEP和GPP样本显示出显著的转录组和基因病理重叠,只有2个差异表达基因 (DEG) 区分它们.
- AGEP和GPP都与PPP,PSO和ADR明显不同.
- 药物诱导的GPP和AGEP在转录组形状,免疫反应模式或免疫细胞组成上没有差异;然而,非药物诱导的GPP表现出比AGEP更高的TH17细胞相关基因表达和中性粒细胞数量.
结论:
- 建议AGEP是IL-36相关 pustulosis的谱内的药物诱导变体,包括GPP.
- 确定了AGEP和GPP之间共享的分子特征.
- 这一发现支持IL-36抑制作为所有IL-36相关 pustulosis亚型的潜在治疗策略.

The JAK-STAT Signaling Pathway
8.6K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

T Cell Types and Functions
830
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
