Some of the best examples of the power of cellular immunity may be found in the many experiments in which transfer of cells can induce autoimmune disease in animals and humans as well as rejection of an organ graft in both animals and humans by cells. The separation of human and cellular immunity was further advanced by the

For example, older adults show declines in cellular immunity, and it appears that the pres-ence of depression exacerbates age-related immune altera-tions (Schleifer et al., 1989; Andreoli et al., 1993).

The main effector cells of innate immunity are macrophages, neutrophils, dendritic cells, and natural killer (NK) cells (Table 1). Phagocytosis, release of inflammatory mediators, activation of complement system proteins, as well as synthesis of acute phase proteins, cytokines and chemokines are the main mechanisms in innate immunity.
