摘要: Efforts to solve the epidemiologic puzzle of AIDS in Africa are complicated by presence multiple human retroviruses. Simple serologic tests that unambiguously distinguish among infections these retroviruses essential. To end, a partially conserved immunoreactive epitope was identified transmembrane glycoproteins immunodeficiency viruses (HIV) types 1 and 2. Synthetic peptides derived from domains were used sensitive specific immunoassays detect antibodies sera patients infected with HIV-1 or HIV-2. By making single amino acid substitutions peptide, it possible demonstrate strain-specific antibody responses this epitope. Such custom-designed synthesized domain likely newly discovered HIV types, define infection strains, allow detection group-common antibodies.
