Multiple Epitopes from the Mycobacterium tuberculosis ESAT-6 Antigen Are Recognized by Antigen-Specific Human T Cell Lines
1 Jun 2000
Abstract excerpt
A synthetic-peptide approach was used to map epitope regions of the Mycobacterium tuberculosis 6-kDa early secreted antigen target (ESAT-6) by testing human CD4(+) T cell lines for secretion of IFN-gamma in response to recombinant ESAT-6 (rESAT-6) and overlapping 20-mer peptides covering the antigen sequence. The results demonstrate that all of the ESAT-6 peptides screened were able to induce IFN-gamma secretion...
