HIV-1 dynamics in vivo: implications for therapy.
The advent of potent combination antiretroviral therapy has been an important breakthrough in the treatment of HIV-1 infection, resulting in marked reductions in HIV-1-related morbidity and mortality. Antiretroviral therapy has also provided researchers with a powerful tool to perturb the equilibrium of viral production and viral clearance, allowing them to dissect the underlying dynamics that control the pathogenesis of AIDS. Here, we review our current understanding of the sources of HIV-1 production, the estimates for the virion and the host-cell half-lives, and the pathways of virion trafficking and clearance. We also discuss the obstacles that result from the ability of HIV-1 to remain dormant for a prolonged period of time in a subset of long-lived cells, despite an apparently effective antiretroviral treatment.
