Abstract

A synthetic peptide (SP-10-IIIB) with an amino acid sequence [Cys-Thr-Arg-Pro-Asn-Asn-Asn-Thr-Arg-Lys-Ser-Ile-Arg-Ile-Gln-Arg-Gly-Pro -Pro-Gly-(Tyr); amino acids 303-321] from the human immunodeficiency virus (HIV) isolate human T-cell lymphotropic virus type III (HTLV-III) HTLV-IIIB envelope glycoprotein gp120 was coupled to tetanus toxoid and used to raise goat antibodies to HIV gp120. Goat anti-SP-10-IIIB serum bound to the surface of HTLV-IIIB-infected CEM T cells but not to the surface of HTLV-IIIRF-infected or uninfected CEM T cells. Anti-SP-10-IIIB antibodies also selectively bound to gp120 from lysates of HTLV-IIIB cells in immunoblot assays. Twenty-one percent of sera (28 of 175) from patients seropositive for HIV contained antibodies that reacted with SP-10-IIIB in RIA. Human anti-SP-10-IIIB antibodies affinity purified from acquired immunodeficiency syndrome (AIDS) patient serum bound to HTLV-IIIB-infected cells and immunoprecipitated gp120. Goat antibodies to SP-10-IIIB neutralized HTLV-IIIB (80% neutralization titer of 1/600), inhibited HTLV-IIIB-induced syncytium formation, but did not neutralize HIV isolates HTLV-IIIRF or HTLV-IIIMN or inhibit syncytium formation with these isolates. Also, goat antiserum to an homologous synthetic peptide [SP-10-IIIRF(A), (Cys)-Arg-Lys-Ser-Ile-Thr-Lys-Gly-Pro-Gly-Arg-Val-Ile-Tyr] from gp120 of HIV isolate HTLV-IIIRF inhibited syncytium formation by HTLV-IIIRF, but did not inhibit syncytium formation by HTLV-IIIB or by HTLV-IIIMN. Thus, the amino acid sequences of SP-10-IIIB and SP-10-IIIRF(A) define homologous regions of gp120 that are important in type-specific virus neutralization. The identification of these type-specific neutralizing epitopes should facilitate the design of a polyvalent, synthetic vaccine for AIDS.
