Description:
Antiretroviral treatment (ART) of HIV infection suppresses viral replication. Yet if ART is stopped, virus reemerges because of the persistence of infected cells. We evaluated the contribution of infected-cell proliferation and sites of proviral integration to HIV persistence. A total of 534 HIV integration sites (IS) and 63 adjacent HIV env sequences were derived from three study participants over 11.3 to 12.7 years of ART. Each participant had identical viral sequences integrated at the same position in multiple cells, demonstrating infected-cell proliferation. Integrations were overrepresented in genes associated with cancer and favored in 12 genes across multiple participants. Over time on ART, a greater proportion of persisting proviruses were in proliferating cells. HIV integration into specific genes may promote proliferation of HIV-infected cells, slowing viral decay during ART.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4230336/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4230336/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Thor A -- McLaughlin, Sherry -- Garg, Kavita -- Cheung, Charles Y K -- Larsen, Brendan B -- Styrchak, Sheila -- Huang, Hannah C -- Edlefsen, Paul T -- Mullins, James I -- Frenkel, Lisa M -- 201311CVI-322424-244686/Canadian Institutes of Health Research/Canada -- K23 AI077357/AI/NIAID NIH HHS/ -- K23AI077357/AI/NIAID NIH HHS/ -- P30 AI027757/AI/NIAID NIH HHS/ -- R01 AI091550/AI/NIAID NIH HHS/ -- R01 AI111806/AI/NIAID NIH HHS/ -- R01AI091550/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2014 Aug 1;345(6196):570-3. doi: 10.1126/science.1256304.
