Primary murine cells as a model for HIV-1 infection.

ABSTRACT

Immortalized and transduced cell lines are traditionally used in model of the HIV-1 life cycle. Primary cells may better represent the tissue of origin and events in vivo. We utilized an HIV-1/murine leukemia A4070 pseudotype virus and human Cyclin T1 to replicate HIV-1 in primary murine cells, and demonstrate that primary murine cells support HIV-1 infection better than immortalized cells.
