1 CD4+T淋巴细胞在HIV感染者和艾滋病病人体内的变化规律1.1感染HIV后CD4+T细胞减少机制HIV感染者血液中CD4+T细胞以每年25个/μL～40个/μL的幅度下降,出现症状时CD4+T细胞<300个/μL,如其急转直下下降到200个/μL,则为疾病恶化的先兆。据报道,感染HIV的CD4+T细胞所占总比率,在无症状HIV感染者的外周血中最多占1/10 000;AIDS病人外周血可达1/200,淋巴结中+
1 CD4 + T lymphocytes in HIV-infected and AIDS patients in vivo 1.1 HIV infection after CD4 + T-cell reduction mechanism HIV-infected blood CD4 + T cells decreased by 25 / μL ~ 40 / μL amplitude , When the symptoms of CD4 + T cells <300 / μL, if its sharp down straight down to 200 / μL, then the disease is a precursor to deterioration. It is reported that the overall proportion of HIV-infected CD4 + T cells in peripheral blood of asymptomatic HIV-infected patients accounted for up to 1 / 10,000; AIDS patients peripheral blood up to 1/200, lymph node +
