初发系统性红斑狼疮患者外周血CD4+CD25+调节性 T细胞和TGF-β1含量
【目的】 了解初发系统性红斑狼疮(SLE)患者外周血中CD4+CD25+调节性T细胞和TGF-β1在SLE发病中的作用。 【方法】 流式细胞仪检测25例初发未治疗的SLE患者和15例健康对照者外周血单个核细胞中CD4+CD25+、CD4+CD25+ Foxp3+调节性T细胞占CD4+ T 细胞的百分比,ELISA检测血清中TGF-β1含量。【结果】 SLE患者PBMC中CD4+CD25+ T细胞、CD4+CD25+Foxp3+ T细胞占CD4+ T细胞百分比均较健康对照组明显减少(分别为7.9 ± 2 ...

口腔白斑病是一种发病率高的潜在恶性黏膜疾患,巨噬细胞在口腔白斑病恶性转化中发挥重要调控作用,但该过程的分子机制研究存在不足。近年研究发现巨噬细胞M2极化对口腔白斑恶性转化具有显著影响,且该过程受到免疫细胞、微生物、细胞因子、细胞外基质等一系列复杂的网络调控。因此本文就巨噬细胞在口腔白斑中的生物学功能、亚型以及其极化的调控因素进行综述,并结合课题组在口腔胞内定植菌与黏膜恶性肿瘤关系的前期研究基础,提出口腔胞内定植菌如牙龈卟啉单胞菌等可能通过促进巨噬细胞M2极化诱导免疫抑制微环境并最终促进白斑恶性转化的机制,
