Abstract
There is evidence linking psychosocially mediated immunological alterations with cancer, infectious illness, and HIV progression. The data reviewed suggest that immune modulation by psychosocial stressors and/or interventions may importantly influence health status. The research literature also suggests that the impact of chronic stressors and psychosocial factors on sympathetic nervous system and endocrine function influences the immune system, thereby providing shared mechanisms that may impact on disease susceptibility and progression across a broad spectrum of disorders. A better understanding of individual vulnerability, such as occurs with aging, may help to pinpoint those at greatest risk.
