By its very nature, psychoneuroimmunology bridges the traditional disciplines of psychiatry, psychology, neurology, endocrinology, immunology, neuroscience, internal medicine, and even surgery wound healing. Fetal alcohol exposure can permanently affect endocrine and immune responses.


More modern work has suggested immunopathology of neurotransmitter receptors, both psiconeuroinmunplogia and dopaminergic.


The Psychoneuroimmunology of Cancer. By the late s and early s, animal experiments implied that stress could affect both humoural and cellular immunity.

Beta-endorphin is a stimulant of NK cell activity. Psychiatric symptoms, besides cognitive defects, probably also cytokine-induced, also occur in conjunction with HIV infection primarily of microglia of the brain including apathy, withdrawal, psychosis, and regressive behaviours. The field is usually referred to as psychoneuroimmunology or “PNI”.

Its basic scientific aspects involve understanding the complex interaction of neuroendocrine and immunologically generated networks in maintaining health and combating disease. The most critical paper to establish credibility and significance of brain-immune communication, however, was that of Robert Ader and Nicholas Cohen in psicojeuroinmunologia taste-aversion conditioned psiconeurkinmunologia.
