Huygen et al., Infect. Immun. 61:2687-2693, 1993). These monoclonal antibodies were used to screen an M. bovis BCG genomic library made in phage lambdagt11. The gene encoding a 233-amino-acid (aa) protein, including a putative 26-aa signal sequence, was isolated, and sequence analysis indicated that the protein was 98% identical with the M. tuberculosis Lppx protein and that it contained a sequence 94% identical with the M. leprae 38-mer polypeptide 13B3 recognized by T cells from killed M. leprae-immunized subjects. Flow cytometry and cell fractionation demonstrated that the 22-kDa CF protein is also highly expressed in the bacterial cell wall and membrane compartment but not in the cytosol. C57BL/6, C3H, and BALB/c mice were vaccinated with plasmid DNA encoding the 22-kDa protein and analyzed for immune response and protection against intravenous M. tuberculosis challenge. Whereas DNA vaccination induced elevated antibody responses in C57BL/6 and particularly in C3H mice, Th1-type cytokine response, as measured by interleukin-2 and gamma interferon secretion, was only modest, and no protection against intravenous M. tuberculosis challenge was observed in any of the three mouse strains tested. Therefore, the 22-kDa antigen seems to have little potential for a DNA vaccine against tuberculosis, but it may be a good candidate for a mycobacterial antigen detection test.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><custom1><style face="normal" font="default" size="100%">https://www.ncbi.nlm.nih.gov/pubmed/10678905?dopt=Abstract</style></custom1><section><style face="normal" font="default" size="100%">1040</style></section></record></records></xml>
