Variation in HIV's ability to disable host defenses contributes to rapid evolution

... of the reasons HIV is so difficult to contain and treat is its rapid evolution. Understanding how host defenses and viral countermeasures contribute to that evolution is vital. Host cells produce two proteins that mutate HIV DNA and interfere with the virus's ability to replicate. But HIV produces a prot...

Study shows how retinoic acid enters a cell's nucleus
