(Submitter supplied) The neurodegenerative process in HIV encephalitis (HIVE) is associated with extensive damage to the dendritic and synaptic structure that often leads to cognitive impairment. Several mechanisms might be at play, including release of neurotoxins, oxidative stress and decreased activity of neurotrophic factors. Furthermore, HIV-mediated dysregulation of genes involved in neuronal maintenance might play an important role. more...

Analysis of brain frontal cortex of HIV-seropositive patients with HIV encephalitis (HIVE). HIVE affects >40% of AIDS patients, promoting neurodegeneration and cognitive impairment. Results suggest HIV-mediated dysregulation of genes involved in neuronal maintenance might play an important role.

(Submitter supplied) Antiretroviral therapy (ART) has reduced morbidity and mortality in HIV infection; however HIV-1-associated neurocognitive disorders (HAND) persist despite treatment. We used microarray analysis in post-mortem brain tissues to determine ART effectiveness in the brain and to identify molecular signatures of HAND under ART.

Analysis of postmortem brain of ART-treated, HIV-1-associated neurocognitive disorders (HAND) patients. ART reduces morbidity and mortality in HIV infection, but HAND persist despite treatment. Results provide insight into ART effectiveness in brain and into molecular signatures of HAND under ART.

(Submitter supplied) Analysis of HIV-associated neurocognitive disorder (HAND) in peripheral monocytes at the gene expression level. The hypothesis tested in the present study was that monocyte gene expression would be predictive of HAND. Results provide information of the associations between monocytes and global neurocognitive function.
