ABSTRACT:
Vaccines effective in the inhibition of infection caused by the family of retroviruses, HTLV-III, Human T-Cell Leukemia Virus, LAV, Lymphadenopathy-associated virus, ARV-2, AIDS-Related Virus, (AIDS and AIDS-Related Complex) have been developed from an antisera prepared against thymosin .alpha..sub.1 (T.alpha..sub.1), a thymic hormone, as well as from antisera to synthetic peptide fragments of T.alpha..sub.1 and antisera to synthetic peptide fragments inclusive of amino acid positions 92-109 of the p17 gag core protein of HTLV-III, LAV and ARV-2. In this 18 amino acid primary sequence there is a 44 to 50% homology between the gag protein and T.alpha..sub.1. Immunoglobulin (IgG)-enriched preparations of the T.alpha..sub.1 antisera have enhanced activity in blocking vital replication. A diagnostic test capable of directly detecting the presence of HTLV-III, LAV, ARV-2 and related retroviruses associated with AIDS and ARC is also described.
