immune response involving T cells targeting infected or abnormal cells
Cell-Mediated Immunity (CMI) is a type of immune response that does not involve antibodies but instead relies on the activation of certain immune cells, particularly T cells, to fight off pathogens, infected cells, and cancer cells. This form of immunity is crucial for defending against intracellular pathogens, such as viruses and some bacteria, and plays a significant role in transplant rejection and autoimmune diseases.
