摘要: In a study of the immunologic significance genetic diversity present within single isolates human immunodeficiency virus type 1 (HIV-1), neutralization viruses derived from molecular clones HIV-1 strain HTLV-IIIB by an extensive panel sera was compared. Sera HIV-1-infected patients and goats immunized with polyacrylamide gel-purified envelope glycoprotein (gp120), native gp120, or gp120-derived recombinant peptides, showed marked heterogeneity in neutralizing activity against these closely related viruses. The change amino acid residue gp120 may account for such "clonal restriction" activity.
