最近部分研究表明，宿主对于Ⅰ型人类免疫缺陷病毒（HIV－1）的免疫功能与疾病进展有关。具有表现在，HIV－1特异性细胞毒性T淋巴细胞数量随病程减少，而可检测到细胞毒性T淋巴细胞的病人其病情相对稳定。在HIV－1感染的早期，由于宿主的免疫性病毒复制有一个下降的过程。但是
Recently, some studies have shown that the host’s immune function against type 1 human immunodeficiency virus (HIV-1) is related to disease progression. It has been shown that the number of HIV-1-specific cytotoxic T lymphocytes decreases with the course of disease and that patients with detectable cytotoxic T lymphocytes are relatively stable. In the early stages of HIV-1 infection, there is a descending process due to host immune-virus replication. but
