目的和方法 :在ＨＩＶ感染的早期及无症状的病毒携带者体内ＣＤ+4Ｔ淋巴细胞对抗原和有丝分裂原刺激缺乏ＩＬ - 2表达和增殖反应 ,甚至在ＣＤ+4Ｔ淋巴细胞进行性减少之前就已经有明显的免疫缺陷。形成这一损伤的确切机制尚不十分清楚 ,但已有研究证实ＨＩＶｇｐ1 2 0和ＣＤ4分
PURPOSE AND METHODS: CD + 4T lymphocytes stimulate both antigen and mitogen-deficient IL-2 expression and proliferative responses in early and asymptomatic HIV carriers of HIV-infected individuals even before the progressive depletion of CD + 4T lymphocytes There are obvious immunodeficiency. The exact mechanism of the formation of this injury is not yet clear, but studies have confirmed that HIVgpl20 and CD4
