To develop effective non-human primate models for coping with numerous HIV-1/AIDS studies, rhesus macaque-tropic HIV-1 (HIV-1rmt) clones with a variety of biological properties are required. Such clones, if available, are powerful tools to experimentally elucidate HIV-1 replication and pathogenicity in host individuals, and also to develop anti-HIV-1 drugs/vaccines. However, only limited numbers of HIV-1rmt clones have been currently reported. In the present study, we generated new HIV-1rmt clones carrying various CCR5-tropic env (envelope) genes by standard recombinant DNA and intracellular homologous recombination techniques. Resultant virus clones contain the env sequences derived from an AIDS-inducible laboratory or two clinically isolated viral strains.We further constructed their variant clones bearing N160K, S304G, or G310R mutation in Env that potentially can change the viruses to better grow. Newly generated clones were analyzed for their virological properties such as Env expression, single-cycle infectivity, and multi-cycle replication ability. Out of a number of new clones examined, two were found to grow better in macaque cells than the previously constructed clone used for comparison. Our study described here constitutes the initial and essential step towards obtaining CCR5-tropic HIV-1rmt clones useful for various basic and clinical research projects on infected individuals.
