To document the in vivo interactions occurring between the immune system and HIV replicating cells, we analyzed using in situ hybridization the production of IL-1.beta., IL-6, IL-2, and INF-.gamma. in eight hyperplastic lymph nodes from HIV-1 infected patients. Numerous IL-1.beta. and IL-6-producing cells associated in clusters were detected in sinuses. Few individual IL-1.beta. and IL-6-producing cells were present in interfollicular and follicular areas. IL-2- and INF-.gamma.-producing cells were observed in all lymph node compartments, with a selective enrichment in germinal centers. The amount and distribution of IL-1.beta.-, IL-6-, and IL-2-producing cells in HIV lymph nodes were different from those found in six HIV unrelated hyperplastic lymph nodes. In contrast, a higher level of INF-.gamma. production was observed in HIV-1 lymph nodes. The CD8+ cells that accumulate in germinal centers of HIV lymph nodes (and not in non-HIV germinal centers) were actively involved in this INF-.gamma. production. INF-.gamma. synthesizing cells were in direct contact with cells containing HIV core antigens and HIV RNA. Thus a high IFN-.gamma. production may characterize anti-HIV T cell immune response, potentially contributing to control of viral spreading as well as to the development of follicle lysis.
