title: [Identification of immunoreactive epitopes in proteins coded by gag, env, and pol genes of the type I human T-lymphotropic virus (HTLV-I) using synthetic peptides].
abstract: Reactivity of 26 synthetic peptides that comprise 12 to 26 amino acid residues corresponding to segments of the gag p19, env gp46, and pol proteins of human T-lymphotropic virus type I toward 31 positive sera was studied using enzyme-linked immunosorbent assay. Specific reactivity with high titers of antibodies (presented in reciprocal dilution values) was detected for the synthetic peptides corresponding to fragments 110-130 and 100-130 (titers up to 4050) of p19, 174-197 (up to 800), 186-201 (up to 4050), 191-215 (up to 1350), 242-257 (up to 800), and 272-292 (up to 450) of gp46. Immunoreactivity of seven peptides, fragments of pol-proteins, was weak. New linear epitopes in the regions 145-158, 272-277, and 292-300 of gp46 were detected. In addition, location of the known linear epitopes in p19 and gp46 was refined on the basis of comparative study of overlapping peptides from these proteins.
