 AB    Immune evasion by the human immunodeficiency virus (HIV) is unexplained
       but may involve the mutation of viral antigens. When cytotoxic T
       lymphocytes engaged CD4-positive cells that were acutely infected with
       HIV bearing natural variant epitopes in reverse transcriptase,
       substantial inhibition of specific antiviral lysis was observed. Mutant
       viruses capable of these transactive effects could facilitate the
       persistence of a broad range of HIV variants in the face of an active
       and specific immune response.
