Disruption of Timing: NeuroHIV Progression in the Post-cART Era.

ABSTRACT: The marked increase in life expectancy for HIV-1 seropositive individuals, following the great success of combination antiretroviral therapy (cART), heralds an examination of the progression of HIV-1 associated neurocognitive disorders (HAND). However, since the seminal call for animal models of HIV-1/AIDS in 1988, there has been no extant in vivo animal model system available to provide a truly longitudinal study of HAND. Here, we demonstrate that the HIV-1 transgenic (Tg) rat, resembling HIV-1 seropositive individuals on lifelong cART, exhibits age-related, progressive neurocognitive impairments (NCI), including alterations in learning, sustained attention, flexibility, and inhibition; deficits commonly observed in HIV-1 seropositive individuals.
