In the lymph node, stimulated CD4 and CD8 T-cells differentiate into interferon -γ secreting T-helper sort 1 or cytotoxic Tc1 cells, respectively, and granules of CD8 T-cells accumulate molecules similar to granzymes and granulysin 18. More recently, Th17 cells, secreting interleukin -17, IL-21 and IL-22, and regulatory T-cells, secreting IL-10 and remodeling development factor-β, have been implicated in coordinating and balancing these primordial driving forces of the cellular immune response 19, 20. tuberculosis-specific effector cells enter the blood circulation and get entry to sites of irritation, such as the lung (fig. 1⇓).
