Cytotoxic T Lymphocytes and Mucosal Surfaces
The lymphatic system houses large populations of immune cells which are released upon detection of a pathogen.
Classes of T Cells
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
Cell-mediated immunity involves cytotoxic T cells recognizing infected cells and bringing about their destruction.
Regulatory T Cells
Regulatory T cells are a subset of T cells which modulate the immune system and keep immune reactions in check.
T Cell Receptors
The T Cell Receptor (TCR) found on the surface of T cells is responsible for recognizing antigens.
Adaptive Immunity and the Immunoglobulin Superfamily
Adaptive immunity is stimulated by exposure to infectious agents and recruits elements of the immunoglobulin superfamily.
