Area of Science:

  • Neuroscience
  • Immunology
  • Psychoneuroimmunology

Context:

  • Psychosocial stress is a known modulator of the immune system.
  • Recent advances elucidate mechanisms of stress-induced immune alterations and brain-immune interactions.
  • Studies link stressful events to increased susceptibility to infections and neoplastic risks.

Purpose:

  • To review and discuss stress-induced immune changes.
  • To explore the intricate brain-immune interactions.
  • To synthesize current literature on the bidirectional communication between the central nervous system and the immune system.

Summary:

  • Psychosocial stress affects immune cells, leading to reduced phagocytosis, lymphocyte response, and natural killer cell activity.
  • Bidirectional communication pathways involve cytokines, neuropeptides, the autonomic nervous system, and the hypothalamic-pituitary-adrenal axis.
