Human immunodeficiency virus type 1 (HIV-1) infection of dendritic cells (DCs) has been documented in vivo and may be an important contributor to HIV-1 transmission and pathogenesis. HIV-1-specific CD4(+) T cells respond to HIV antigens presented by HIV-1-infected DCs and in this process become infected, thereby providing a mechanism through which HIV-1-specific CD4(+) T cells could become preferentially infected in vivo. HIV-2 disease is attenuated with respect to HIV-1 disease, and host imm...Expand abstract
