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 …

Multiple sclerosis (MS) is the most common demyelinating disorder of the central nervous system. MS is believed to occur in genetically susceptible individuals due to an unknown environmental stimulus. MS patients produce autoantibodies to heterogenous nuclear ribonuclearprotein A1 (hnRNP A1), an RNA binding protein (RBP) highly expressed in neurons. hnRNP A1 functions in pre-mRNA splicing, mRNA trafficking, and translation. Furthermore, the anti-hnRNP A1 antibodies are specific to a N-terminal region termed ‘M9’ which serves as a nuclear export sequence/nuclear localization sequence (NES/NLS) responsible for nuclear/cytoplasmic transport of the protein. In this manuscript we will provide data revealing that anti-hnRNP A1 …
