Longitudinal study reveals HIV-1–infected CD4+ T cell dynamics during long-term antiretroviral therapy

Abstract

Proliferation of CD4+ T cells harboring HIV-1 proviruses is a major contributor to viral persistence in people on antiretroviral therapy (ART). To determine whether differential rates of clonal proliferation or HIV-1–specific cytotoxic T lymphocyte (CTL) pressure shape the provirus landscape, we performed an intact proviral DNA assay (IPDA) and obtained 661 near–full-length provirus sequences from 8 individuals with suppressed viral loads on ART at time points 7 years apart. We observed slow decay of intact proviruses but no changes in the proportions of various types of defective proviruses. The proportion of intact proviruses in expanded clones was similar to that of defective proviruses in clones. Intact proviruses observed in clones did not have more escaped CTL epitopes than intact proviruses observed as singlets. Concordantly, total proviruses at later time points or observed in clones were not enriched in escaped or unrecognized epitopes. Three individuals with natural control of HIV-1 infection (controllers) on ART, included because controllers have strong HIV-1–specific CTL responses, had a smaller proportion of intact proviruses but a distribution of defective provirus types and escaped or unrecognized epitopes similar to that of the other individuals. This work suggests that CTL selection does not significantly check clonal proliferation of infected cells or greatly alter the provirus landscape in people on ART.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.

Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
