The effects of HIV-associated extracellular vesicles on mitochondrial dysfunction in brain microvessels

Combined antiretroviral therapy (cART) suppresses HIV replication, but 30-60% of infected patients suffer from severe HIV-1 associated neurocognitive disorders (HAND). However, the mechanisms underlying HAND are unclear and this lack of information has prevented the development of effective science-driven treatments. Our data have provided key information connecting etiology, especially by showing that pathogenic contents of plasma extracellular vesicles (EVs) from either chronic SHIV-infected and cART treated rhesus macaque (RM) or HIV(+)–cART treated patients play a key role in the development and progression of HAND. Moreover, our novel findings provide the first evidence that EVs…
