We have established immunological assays to assess cellular immunity at mucosal surfaces and in the blood. Using these assays we can show that macaques that are infected with SHIV respond to SHIV antigens in vitro by making gamma-interferon. This response is stronger in the gut than in the periphery. We also used these methods to test macaques immunized with autologous dendritic cells that were transfected with and HIV-1 provirus mutated in the integrase gene. These animals showed a response similar to the infected animals, and we determined that, as expected, the responding cells were in fact CD69+ activated T cells. In addition we have shown that these animals have a classic cytotoxic T lymphocyte response to HIV-1 antigens. FUNDING NIH grants RR00166 and AI26503.

我们已经建立了免疫学测定来评估细胞 粘膜表面和血液中的免疫力。 使用这些测定， 表明感染了SHIV的猕猴对SHIV有反应 在体外制造γ-干扰素。 这种反应 肠道比外周更强 我们也使用了这些方法 测试用自体树突细胞免疫的猕猴， 用整合酶基因突变的HIV-1前病毒转染。 这些动物表现出与受感染动物相似的反应， 我们确定，正如预期的那样， CD 69+活化T细胞。 此外，我们还发现这些动物 对HIV-1抗原有典型的细胞毒性T淋巴细胞反应。 资助NIH赠款RR 00166和AI 26503。
