Understanding human immunodeficiency-1 (HIV-1) replication and latency in different reservoirs is an ongoing challenge in the care of patients with HIV/AIDS. A mathematical model was created that predicted HIV-1 and simian immunodeficiency virus (SIV) infection dynamics within the brain during effective combination antiretroviral therapy (cART). By developing a two compartment mathematical approach, a predictive model was generated from existing empiric data. Based on previous reports quantifying total viral DNA levels in brain from HIV-1 and SIV infections, estimates of proviral DNA burden were made, which were fit to a mathematical model predicting viral accrual in brain macrophages from primary infection. To our knowledge this is the first mathematical modeling study to quantify HIV-1 and SIV infection dynamics in the brain. Our modeling study indicates that HIV-1 and SIV provirus burdens in brain increase slowly over time. Assuming antiretroviral therapy suppresses HIV-1 infection outside the brain, an effective antiretroviral therapy could eradicate HIV-1 infection in the brain, albeit over a decade for patients without neurological complications and over two decades for those with HAND.
