It is unknown how the major histocompatibility complex class I (MHC-I) pathway samples mycobacterial antigens," scientists writing in the journal Infection and Immunity report. "CFP10 and ESAT6 are important virulence factors secreted by M. tuberculosis, and they are immunodominant targets of the human and murine T-cell response.
