Abstract

Mycoplasmas have been incriminated in setting the stage for HIV infection and full-blown AIDS. We tested the possible involvement of mycoplasmas in activation of HIV. Two cell lines, 293 fibroblasts and Jurkat CD4+ T-cells, transfected with plasmids harboring a transcription fusion construct between HIV-long terminal repeat (HIV-LTR) and either luc or cat genes, were infected with several mycoplasmas (M. fermentans; M. penetrans, M. pirum and Ureaplasma urealyticum) and the reporter gene expression was monitored. The data presented here suggest that mycoplasmas, and specifically their membranes, play a role in the activation of HIV-LTR mediated transcription.
