The First Edition of Psychoneuroimmunology collated the information then available that implicated neural and endocrine processes in the modulation of immunity in an attempt to identify and define a new field of study. This new edition documents the past ten years of research and provides unequivocal evidence of behavior-neural-endocrine-immune interactions. Neural, endocrine, and immune processes are interrelated and comprise an integrated system of defense**Hormones and neurotransmitters serve an immunoregulatory function via the signaling of lymphocytes and other cells of the immune system**Products of an activated immune system signal the nervous and endocrine systems**Behavioral factors are capable of influencing immune function and vice versa**Behavioral effects on health and illness could operate through the immune system - from Amzon
