In the brain, HIV predominantly infects microglia/macrophages and astrocytes to a lesser extent. These cells form virus reservoirs with low levels of infection that are very hard to eradicate. Even though the use of cART increases survival rate in HIV patients, the virus persists as a chronic condition. cART is not able to effectively cross the BBB, control HIV replication, or attenuate inflammation in brain reservoirs. Therefore, the virus still causes neuronal dysfunction, pain-related pathology, and ultimately HAND. In this study, we decided to test the hypothesis that a serpin-derived small peptide, SP16, can serve as an anti-viral, anti-inflammatory, pro-survival, …

Persistence of HIV-1 reservoirs within the Central Nervous System (CNS) remains a significant challenge to the efficacy of potent anti-HIV-1 drugs. The primary human Brain Microvascular Endothelial Cells (HBMVEC) constitutes the Blood Brain Barrier (BBB) which interferes with anti-HIV drug delivery into the CNS. The ATP binding cassette (ABC) transporters expressed on HBMVEC can efflux HIV-1 protease inhibitors (HPI), enabling the persistence of HIV-1 in CNS. Constitutive low level expression of several ABC-transporters, such as MDR1 (a.k.a. P-gp) and MRPs are documented in HBMVEC. Although it is recognized that inflammatory cytokines and exposure to xenobiotic drug substrates (e.g HPI) can …
