dc.description.abstract | PURPOSE OF REVIEW: To summarize the evidence in the literature that supports the central nervous system (CNS) as a viral reservoir for HIV-1 and to prioritize future research efforts. RECENT FINDINGS: HIV-1 DNA has been detected in brain tissue of patients with undetectable viral load or neurocognitive disorders, and is associated with long-lived cells such as astrocytes and microglia. In neurocognitively normal patients, HIV-1 can be found at high frequency in these cells (4% of astrocytes and 20% of macrophages). CNS cells have unique molecular mechanisms to suppress viral replication and induce latency, which include increased expression of dominant negative transcription factors and suppressive epigenetic factors. There is also evidence of continued inflammation in patients lacking a CNS viral load, suggesting the production and activity of viral neurotoxins (for example, Tat). SUMMARY: Together, these findings provide evidence that the CNS can potentially act as a viral reservoir of HIV-1. However, the majority of these studies were performed in historical cohorts (absence of combination antiretroviral therapy or presence of viral load), which do not reflect modern day patients (combination antiretroviral therapy-treated and undetectable viral load). Future studies will need to examine patient samples with these characteristics to conclusively determine whether the CNS represents a relevant and important viral reservoir. | - |
