During HIV infection, CTLs identify and target HIV-infected cells by recognizing parts of viral proteins called epitopes. Yet, due to HIV\u2019s rapid replication, the virus may also accumulate mutations, which reduce CTLs\u2019 effectiveness in recognizing infected cells. Such mutations, referred to as CTL escape, are a major problem in the development of an effective vaccine.<\/p>\n<p>Studies in the last decade have shown that CTL responses concurrently target multiple HIV epitopes, yet the effect on HIV dynamics and evolution is not well understood. The new study revisits these questions, and with a re-analysis of the escape data, finds that a vaccine that induces a broad CTL response targeting multiple viral epitopes should limit viral escape and provide control of HIV infection.<\/p>\n<p>The paper can be found at http:\/\/journals.plos.org\/ploscompbiol\/article?id=10.1371\/journal.pcbi.1004492<\/p>\n<p><strong>Citation<\/strong>: Leviyang S, Ganusov VV (2015) Broad CTL Response in Early HIV Infection Drives Multiple Concurrent CTL Escapes.
