Cellular immunity is based on the action of granulocytes and monocytes.

Cellular Immunity

One of the three general categories of immune response, based on the action of a class of blood cells called T-lymphocytes. The “T” designation refers to the locus of their production, the thymus gland. Cellular immunity results from a cascade of actions of various types of T-lymphocytes.

Monocytes

A type of white blood cell that plays a critical role in the immune system by killing pathogens, removing dead cells, and stimulating the action of other immune cells.
