Abstract

Researchers in the field of psychoneuroimmunology (PNI) study the intricate multifaceted relationship between changes in the nervous system that accompany psychological states and corresponding changes in immune system function, in the context of health and disease. This chapter outlines the physiological basis for the bidirectional relationships between the nervous and immune systems, noting the advancement in the knowledge of how the autonomic system plays a supervisory role in monitoring activity of the immune system. Naturalistic stressors and those created in laboratory settings provide useful models for studying both the acute and chronic influences of psychological states (e.g., stress) on immune function. Furthermore, individual differences in mood and coping strategies may moderate these stress-immune relationships. These individual differences occur within a broader context of social relationships, which provide benefits or impairments in immune function and health. Research on social integration, social support, loneliness, and marriage reveals the importance of the connection between interpersonal relationships and health. Finally, intervention strategies aimed at reducing psychological distress provide hope for individuals suffering from immune-related diseases, including those with cancer and HIV.
