How Sleep and Immune Signals Influence Each Other

AI simplified

Abstract

Sleep disorders may disrupt cytokine production and shift secretion peaks from night to day.

  • Cytokines like interleukin-1β and tumor necrosis factor-α mediate the relationship between sleep and inflammation.
  • Sleep deprivation can lead to increased daytime fatigue and impaired cognitive performance.
  • Altered cytokine rhythms could heighten susceptibility to infections and systemic inflammation.
  • Insufficient sleep may prime immune cells to trigger stronger pro-inflammatory responses.
  • There is a potential feedback loop between neuroendocrine pathways and inflammatory dysregulation affecting sleep patterns.
