这些确诊较晚,确诊时CD4细胞计数较低的HIV感染者通常被称为“HIV晚发现者”。 国际上对于HIV晚发现者的定义尚无通用标准,世界卫生组织(WHO)的指南仅定义了晚期HIV疾病为CD4细胞计数<200个/μL[1],美国疾病控制预防中心(CDC)则根据CD4细胞计数划定了不同级别的HIV感染(<200个/μL为三级HIV感染,200-499个/μL...

A robust primary immune response has been correlated with the precursor number of antigen-specific T cells, as identified using peptide MHCII tetramers. However, these tetramers identify only the highest-affinity T cells. Here we show the entire CD4+ T-c
CD4/CD8比值:非艾滋相关疾病的指标 CD4+T淋巴细胞是HIV感染最主要的靶细胞,HIV感染人体后会引起CD4+T淋巴细胞进行性减少。近年来,抗逆转录病毒治疗(ART)取得了良好效果,在大多数接受治疗的HIV感染者中可达到...

近日,来自澳大利亚墨尔本大学的Sammy Bedoui 在Nature Immunity杂志上在线发表题为CD4+ T cell calibration of antigen-presenting cells optimizes antiviral CD8+ T cell immunity的研究文章。该论文揭示固有免疫信号IFNα/β或LPS预处理赋予DCs在接收CD4+T细胞CD40刺激后通过增强p65, IRF1和FOS转录因子活动以更快更...
T cells are known to have a role in the immune response against cancer, because CD4+ T cells facilitate the activation of cytotoxic CD8+ T cells and the antitumor effects of CD8+ T cells are limited in the absence of CD4+ T cells.15,16 In addition, CD4+ T cells can also target ...
