Cellular immune response to Mycobacterium tuberculosis-speciWc antigen culture Wltrate protein-10 in south India

Abstract

The Mycobacterium tuberculosis (M. tuberculosis)- speciWc culture Wltrate protein-10 (CFP-10) is highly recognized by M. tuberculosis infected subjects. In the present study, the proliferative response and IFN-� secretion was found for C-terminal peptides of the protein (Cfp651–70, Cfp761–80, Cfp871–90, and Cfp981–100). The alleles HLA DRB1 *04 and HLA DRB1 *10 recognized the C-terminal peptides Cfp7, Cfp8, and Cfp9 in HHC. Cfp6 was predominantly recognized by the alleles HLA DRB1 *03 and HLA DRB1 *15 by PTB. The minimal nonameric epitopes from the C-terminal region were CFP-1056–64 and CFP-1076–84. These two peptides deserve attention for inclusion in a vaccine against tuberculosis in this region
