Immune function describes the body’s response to infection (i.e., the invasion by microorganisms), neoplasms (cancers), and tissue damage.
Successful immune function establishes a state of immunity (Latin: immunitas, “freedom from”) against infection and disease. Immunity relies on a multifaceted and flexible defense system, the immune system that protects against microorganisms, like bacteria and viruses, and other foreign invaders, like toxins. The immune system also regulates repair processes in response to tissue damage, and it protects against neoplasms (cancers). The immune system does not operate autonomously. It is, among others, influenced by central nervous system processes and their neurohormonal outflows, which, in turn, are shaped by social and psychological factors. Likewise, activities of the immune system have profound effects on those in the central nervous system, influencing mood, behavior, and cognition.
