The molecular mechanisms by which H pylori triggers and maintains the local immune response are complex, but there is evidence that cytokines produced by both immune and non-immune cells contribute to amplify the ongoing inflammation. H pylori infection is associated with a marked mucosal induction of T helper (Th) type 1 and Th17-type cytokines that is governed by specific antigen-presenting cell-derived molecules, such as interleukin (IL)-12 and IL-23. In this paper, we will review the available data on the expression and role of IL-23 and IL-17 in H pylori- related gastritis.展开更多
目的探讨乙肝病毒(hepatitis B virus,HBV)感染患者外周血中几种细胞因子在疾病慢性化及疾病进展中的作用。方法分离HBV慢性感染者及健康人外周血,采用酶联免疫吸附法(ELISA法)检测IL-17、IL-23、TGF-β和IL-10的表达及其与乙肝患者肝...目的探讨乙肝病毒(hepatitis B virus,HBV)感染患者外周血中几种细胞因子在疾病慢性化及疾病进展中的作用。方法分离HBV慢性感染者及健康人外周血,采用酶联免疫吸附法(ELISA法)检测IL-17、IL-23、TGF-β和IL-10的表达及其与乙肝患者肝功能指标及血清中病毒载量的关系。结果乙肝患者血清中IL-17、IL-23和TGF-β与健康对照比较无明显差异,但IL-10显著增加,IL-17、IL-10与转氨酶水平正相关,TGF-β与转氨酶水平负相关,而IL-10与乙肝病毒DNA载量正相关。结论IL-17、IL-10及TGF-β与HBV感染者肝细胞的炎性损伤有关,对于乙肝患者肝纤维化及疾病进展程度具有提示意义,而IL-10具有促炎和耐受的双重作用,可以预测乙肝感染慢性化及病毒持续感染。展开更多
