However, the function of these T cells and the mechanism by which they provide protection is still unknown." "We have previously shown that CD8(+) T cells specific for the mycobacterial Ags CFP10 and TB10.4 accumulate in the lungs of mice following Mtb infection and have cytolytic activity in vivo.
