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.
