Numerous studies have demonstrated that the ESAT-6 and CFP-10 protein antigens stimulate IFN- responses in T cells from individuals infected with M. tuberculosis but generally not from uninfected or BCG-vaccinated persons. Memory B cells can proliferate to produce more memory cells or plasma B cells. For example, a mutation that hyperactivates the oncogene Ras and another that inactivates the tumor suppressor pRb is far more tumorigenic than either protein alone.
