T Cells and Cellular Immunity

The lymphatic system houses large populations of immune cells which are released upon detection of a pathogen.

T cells play a central role in cell-mediated immune response through the use of the surface T cell receptor to recognize peptide antigens.

Cell-mediated immunity involves cytotoxic T cells recognizing infected cells and bringing about their destruction.

Regulatory T cells are a subset of T cells which modulate the immune system and keep immune reactions in check.

The T Cell Receptor (TCR) found on the surface of T cells is responsible for recognizing antigens.

Adaptive immunity is stimulated by exposure to infectious agents and recruits elements of the immunoglobulin superfamily.
