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.).
