研究已发现慢性病毒感染后大约一个月开始,体内具有“记忆”功能的CD8T细胞会被逐渐耗竭,从而降低了机体对疾病的防御能力,但目前为止,该种现象发生的分子机制并不清楚。为了找到原因,美国达那-法伯癌症研究所和艾莫里大学的研究者进行了一项研究,结果发现小鼠体内存在能够逆转 Studies have found that approximately one month after chronic viral infection begins, CD8 T cells with “memory” function in vivo are depleted, thus reducing the body’s defenses against the disease, but so far the molecular mechanism by which this phenomenon occurs is not clear . In order to find the reason, a study was conducted by researchers at the Dana-Farber Cancer Institute and Emory University in the United States. The results showed that there was a reversible
