A Mycobacterium tuberculosis operon encoding ESAT-6 and a novel low-molecular-mass culture filtrate protein (CFP-10).
The early secreted antigenic target 6 kDa protein (ESAT-6) is a potent T-cell protein antigen synthesized by Mycobacterium tuberculosis. Its corresponding gene (esat-6) is located in RD1, a 10 kb DNA region deleted in the attenuated tuberculosis vaccine strain Mycobacterium bovis BCG. The promoter region of M. tuberculosis esat-6 was cloned and characterized. A new gene, designated lhp and cotr...
متن کاملPreparation of immunochromatographic strips for rapid detection of early secreted protein ESAT-6 and culture filtrate protein CFP-10 from Mycobacterium tuberculosis
The early secreted protein early secretory antigenic target 6(ESAT-6) and the culture filtrate protein 10 (CFP-10) are 2 antigens that are specific to Mycobacterium tuberculosis. These 2 antigens are good targets for tuberculosis (TB) detection.To rapidly diagnose TB across a variety of samples, we developed colloidal gold immunochromatographic strips (ICSs) based on ESAT-6 and CFP-10.The strip...
متن کاملComparative analysis of B- and T-cell epitopes of Mycobacterium leprae and Mycobacterium tuberculosis culture filtrate protein 10.
Culture filtrate protein 10 (CFP-10) from Mycobacterium tuberculosis is a well-characterized immunodominant 10-kDa protein antigen known to elicit a very potent early gamma interferon response in T cells from M. tuberculosis-infected mice and humans. The sequence of the Mycobacterium leprae homologue of CFP-10 shows only 40% identity (60% homology) at the protein level with M. tuberculosis CFP-...
متن کاملTuberculin skin testing and in vitro T cell responses to ESAT-6 and culture filtrate protein 10 after infection with Mycobacterium marinum or M. kansasii.
T cell responses to ESAT-6 and culture filtrate protein 10 (CFP-10), antigens expressed by Mycobacterium tuberculosis but not by M. bovis bacille Calmette-Guérin (BCG), were found to discriminate reliably between infection with M. tuberculosis and BCG vaccination. Because the esat-6 and cfp-10 genes occur in M. kansasii and M. marinum, T cell responses to ESAT-6 and CFP-10 were investigated in ...
متن کاملMycobacterium tuberculosis ESAT-6 antigen immunogenicity in Owl Monkeys
Several ESAT-6-based vaccines have been widely studied in different animal models, presenting potent ability to induce both cellular and humoral responses. As ESAT-6 is a well-characterized mycobacterial antigen, its capacity to induce immune responses in a nonhuman primate model has been evaluated. The immunization of recombinant ESAT-6 (rESAT-6) in Aotus nancymaae monkeys has elicited a stron...
