Usage: CD8 positive T-cells are mediators of adaptive immunity. These are cytotoxic suppressor T-cells which restrain certain types of immune response and are important for immune defence against intracellular pathogens and for tumor surveillance. They also contribute to excessive immune response leading to immune mediated damage.
