l 不确定是否所有CRTAM+CD4+T都能获得细胞毒性(CRTAM在刺激48h后会下调,重新激活后又再表达); l 在急性流感模型中CD4 CTL显示出与CRTAM表达相关的抗原特异性细胞毒性;memory CD4 CTL是否在炎症部位具有抗原特异性仍有待被有效阐明。 三、CD4 CTL研究的指标选择 相关指标marker选择: 脱颗粒相关:LAMP、LAMP-1(CD10...
随着精细针吸取淋巴结或组织活检的日益普及，结合最近开发的细胞因子非依赖的识别病原体特异性记忆CD4+T细胞的方法，有助于更多种类的CD4+记忆亚群的检测。激活诱导标志物（activation-induced marker, AIM）试验利用OX40和CD25在抗原刺激后的上调现象，特别适用于在不知道确切CD4+ T细胞表位的情况下检测记忆CD4+ T细胞。
同时出生后早产儿肠道上皮组织中含有更丰富的CD4+T细细胞。 胎儿肠道中CD4+T细胞类型主要为效应记忆性T(Tem)细胞 外周血中T细胞分化遵循线性途径,主要从幼稚CD4+T细胞开始逐渐分化。但是在胎儿肠道中主要为CD45RA-CCR7-CD4+ T cells. 这里给大家稍微介绍下这个标记分类:根据CD45RA和CCR7的表达,CD4+T细胞可分为T...
