 AB    OBJECTIVE: Any information (especially new) about AIDS is important.
       There aren't whole universal picture (even scetch) about nature,
       reasons, mechanisms for hypervariability formation by AIDS in biopshere.
       METHODS: theoretical reseaches show the main mechanisms of hypothetical
       concept may be two: IERT-individual epitope reverse translation (when
       there are non-single aminonucleic correspondence for genetic
       code--including mutations of different genes); and transfer of special
       vector-like nucleic sequences (VLNS-transfer) with nucleic equivalent of
       concrete epitope into. RESULTS: we know specific immune responce need
       the cognate physical contact between antigenpresentative cell
       (macrophage) and T-help, T-T and T-B cell's analogic contacts.
       DISCUSSION: supposedly both mechanisms are used by immune responce.
       Cross of strategic ways (in the same cells macrophages, T-help,
       anothers) for immune responce formation and viruse spreading (the
       first); and use the same hypothetical mechanisms (IERT and
       VLNS-transfer-the second) probably lead to hypervariability by AIDS.
       This mechanisms perhaps can exploit for diversity formation by different
       normal and pathologic processes (antibody formation, drug resistance,
       etc.).
