IL12andStat4DependentSignalingPathwayinTh1Development
Interleukin-12 (IL-12) promotes cell-mediated immunity by inducing Th1 cell differentiation and activation of both T cells and NK cells. Dendritic cells and macrophages in peripheral tissues act as antigen presenting cells and secrete IL-12 as one component of the antigen response, Th1 differentiation. The role of IL-12 in cellular immunity is largely mediated by the STAT-4 transcription factor. STAT-4 is essential f......阅读全文

th1是什么
TH1型免疫反应。1、在医学界：TH1是指TH1型免疫反应，也可叫做TH1细胞主要辅助(细胞)免疫应答。TH指辅助性T细胞，它包括TH1、TH2、TH17和调节性T细胞。2、TH1细胞有助于活化巨噬细胞对抗这些病原体，并破坏它们的逃避策略。 TH1细胞是辅助性T细胞产生的免疫反应，都是由细胞因子介导
Th1细胞的功能
主要是增强吞噬细胞介导的抗感染免疫，特别是抗胞内病原体的感染。IFN-γ（γ干扰素）活化巨噬细胞，增强其杀伤已被吞噬的病原体的能力。还能促进IgG的生成。
什么是TH1细胞
Th1细胞为CD4阳性细胞,其主要功能有分泌IL－2 （白细胞介素2）、IFN－γ（γ干扰素）和TNF－β（β肿瘤坏死因子）等细胞因子,参与调节细胞免疫,引起炎症反应和迟发型超敏反应.
Th1细胞的定义
Th0细胞在IL-12等细胞因子作用下分化而成，Th1细胞为CD4阳性细胞，主要分泌IL-2（白细胞介素2）、IFN-γ（γ干扰素）、TNF（β肿瘤坏死因子）等。功能为参与调节细胞免疫，辅助细胞毒性T细胞分化，介导细胞免疫应答，参与迟发型超敏反应等。 Th1，Th2，Th3，和Th17细胞同属
