New peptide(s) common to mycoplasm adhesion molecule and HIV proteins

摘要

New peptide (I) able to induce in vivo prodn. of antibodies (Ab) in which inhibit infection by HIV comprises an amino acid sequence consisting of a sequence derived from a mycoplasmal protein. Also new are (1) peptides (Ia), derived from the gp/60 or nef proteins of HIV, having a high degree of isology (or homology) with (I) and able to induce Ab with inhibit infection of T-lymphocytes by HIV; (2) the tripeptide TPL; (3) recombinant or hybrid peptides which include (I) or (Ia) sequences; (4) purified proteins (II) from M. pirum (a) having mol. wt. 130 kD (the adhesion) and recognised by Ab raised against GVVSTPLVNLINGQ (Ib) or (b) having mol. wt. below 65 kD; (5) mono- or poly-clonal Ab against (I), (Ia) or the recombinant/hybrid proteins.
