High levels of resistance to challenge with human immunodeficiency virus type 1 SF162 were observed in animals engrafted with peripheral blood mononuclear cells of four long-term nonprogressors (LTNPs). Resistance was abrogated by depletion of CD8(+) T cells in vivo and was observed only in LTNPs with proliferative responses to p24. In a subgroup of nonprogressors, CD8(+) T cells mediated restriction of challenge viruses, and this response was associated with strong proliferative responses to p24 antigen.
在移植了四名长期不进展者(LTNP)外周血单个核细胞的动物中,观察到对1型人类免疫缺陷病毒SF162攻击具有高度抗性。体内CD8(+) T细胞耗竭可消除这种抗性,并且仅在对p24有增殖反应的LTNP中观察到这种抗性。在一部分不进展者中,CD8(+) T细胞介导对攻击病毒的限制,并且这种反应与对p24抗原的强烈增殖反应相关。
