RESUMO
The frequency of anti-CD4 antibodies was determined in the sera or plasma derived from the patients infected with HIV-1 belonging to different genetic subgroups. The anti-CD4-antibodies in a dilution of > or = 1:1000 were found in 14% of the patients infected with the gagA/envA virus characteristic for injectable drug users in East Europe. The frequency of autoimmune antibodies among the HIV-infected patients with envB virus was substantially less (4.4%). Competitive ELISA using monoclonal antibodies to different CD4 domains demonstrated that irrespective of the viral genotype, the autoimmune epitope is located within the D4 or D3/D4 domains of CD4 receptor.
