Early in infection, HIV crosses the blood-brain barrier and induces neuropathology. Viral presence in the CNS coupled with secretion of neurotoxic proteins causes neuroinflammation, glial dysfunction, excitotoxicity, and neuronal death. Despite advances in combined antiretroviral therapy, HIV-infected patients present with a spectrum of cognitive and psychomotor deficits collectively referred to as HIV-associated neurological disorders (HAND). A subset of HAND patients abuses drugs such as opiates like heroin and morphine show an exacerbation and rapid progression of HIV neuropathology; however, the mechanisms of this synergy are not well understood. Autophagy is a lysosomal degradative process which eliminates and recycles cytosolic components …

The effects of alcohol abuse are multi-dimensional since alcohol is widely known to affect both the innate and adaptive immune systems. Recently, epigenetics has come into focus and has been implicated in many diseases as well as substance abuse disorders. Therefore, research efforts of understanding the epigenetic mechanisms underlying substance abuse effects including alcohol abuse have become more predominant.
In our laboratory, we have studied different epigenetic changes induced by alcohol exposure including regulation of histone deacetylases (HDACs), histone quantity, and histone modifications such as acetylation and deacetylation. We have observed differential effects of acute and chronic alcohol exposure in …
