RESUMO

Replication of human immunodeficiency virus type 1 (HIV-1) was inhibited by stable intracellular expression of antisense RNA in the human T-lymphoid cell line Jurkat. When the viral subregion encoding the HIV-1 activator proteins was targeted, the extent of antisense RNA-mediated inhibition was greater than 97% during the first 2 weeks postinfection. Later in the time course, productive HIV-1 infection broke through at high initial infective doses. However, at initial multiplicities of infection equal to or smaller than 0.1, HIV-1 production was not detectable during the 5 weeks of observation. The results underline the effectiveness of stable intracellular antisense RNA expression in inhibiting HIV-1 replication.
