Question

Quizplus · Accepted Answer

T cells interact with the peptide-MHC complex using their T-cell receptors. The TCR recognizes the specific antigenic peptide presented by the MHC molecule. This interaction initiates a series of events that lead to activation of the T cell, including production of cytokines, activation of cytotoxic mechanisms (e.g., granzyme and perforin), and proliferation of effector cells. The interaction is not mediated by antibodies on the surface of the cell, as T cells are not antibody-producing cells.
