Description

The reservoirs of HIV-1 infection that permit maintenance of persistent virus infection (even when virus replication cannot be detected using sensitive assays to quantify plasma HIV-1 RNA levels) are currently unknown. Potential sites for persistent HIV-1 infection include cells with chronic or latent infections, cells present in locations within the body where antiviral drugs may not penetrate in levels sufficient to prevent additional cycles of de novo virus infection (e.g., the central nervous system), the presence of susceptible target cells for virus infection that may not metabolize c...
