title: [Immunosorption of individual HIV proteins and virions].
abstract: Immunosorbents specifically binding native (gp160, gp120, gp41) and recombinant env proteins and HIV-I virions were synthesized on the basis of Sepharose 4B and Silica with immobilized ligands such as gamma-fraction of rabbit antiserum to HIV-I proteins and purified antibodies to env proteins of HIV-I. The possibility was shown of selective extraction of HIV-I virions and individual HIV proteins both in vitro and in vivo. The titer of virus antigens (in ELISA) after perfusion via an immunosorbent of patterns with a high content of virions and HIV-I proteins was 8 times as low as the starting titer (after perfusion via the control sorbent it was 2-fold decreased). Extracorporeal immunosorption in animals after intravenous injection of recombinant env protein permitted the latter's titer to be 5 times lower. After perfusion via the control sorbent the titer dropped by at least 20% as compared with the starting titer. The possibility of using immunosorption in multimodality therapy of AIDS is under discussion.
