What type of lymphocyte is responsible for cell-mediatedimmunity? What are the functions of cell-mediated immunity?

Describe the signal transduction pathway that is activated when LPS binds to TLR-4.

(i) Explain the role of Ras.GTP and Rac.GTP in the formation of active AP-1 during T- cell activation. (ii) Cadmium ions have been shown to be selective blockers of membrane calcium channels. Suppose T lymphocytes are cultured in the presence of cadmium chloride, explain what happens to TCR-triggered signal transduction.
