HIV-associated neurocognitive impairment (HIV-NCI) is a debilitating comorbidity that reduces quality of life in 15-40% of people with HIV (PWH) taking antiretroviral therapy (ART). Opioid use has been shown to increase neurocognitive deficits in PWH. Monocyte-derived macrophages (MDMs) harbor HIV

Lysine acetylation has been discovered in thousands of non-histone human proteins, including most metabolic enzymes. Deciphering the functions of acetylation is key to understanding how metabolic cues mediate metabolic enzyme regulation and cellular signaling.
