新鉴定的细胞因子IL-15增强了从HIV-1血清阳性受试者获得的PBMC的抗原诱导的增殖。与IL-2相比,IL-15可增强自发性和抗原诱导的淋巴细胞增殖反应,但很少增加自发性淋巴细胞增殖。此外,在从15名HIV-1感染患者中获得的淋巴细胞培养物中,循环CD 4-淋巴细胞/微升< 300,IL-15诱导显著的HIV-1表达。(46,21,和71 pg/ml),IL-2诱导显著的HIV-1表达(范围16- > 5000 pg/ml)(P < 0.01,Fischer精确检验)。同时测定马槟榔诱导的自发淋巴细胞增殖和HIV-1表达,发现IL-2诱导HIV-1和淋巴细胞增殖的剂量-反应关系相似。因此,IL-15有助于纠正来自HIV-1感染者的CD 4+淋巴细胞的受损增殖反应,而不具有也可诱导HIV-1表达的IL-2的促有丝分裂作用。
The newly identified cytokine, IL-15 enhanced antigen-induced proliferation of PBMC obtained from HIV-1-seropositive subjects. When compared to IL-2 which enhanced both spontaneous and antigen-induced lymphocyte proliferative responses, IL-15 rarely increased spontaneous lymphocyte proliferation. Additionally, in cultures of lymphocytes obtained from 15 HIV-1-infected patients with < 300 circulating CD4- lymphocytes/microliter IL-15 induced significant HIV-1 expression (46, 21, and 71 pg/ml) in only 3 of 15 experiments and IL-2 induced significant HIV-1 expression (range 16- > 5000 pg/ml) in 11 of 15 experiments (P < 0.01, Fischer's exact test). Simultaneous assays of cytokine-induced spontaneous lymphocyte proliferation and HIV-1 expression revealed similar dose-response relationships for induction of HIV-1 and lymphocyte proliferation by IL-2. Thus, IL-15 helps to correct the impaired proliferative response of CD4+ lymphocytes from HIV-1-infected persons without the mitogenic effect of IL-2 that also may induce HIV-1 expression.
