The immune system exhibits regular biological rhythms, including daily (circadian) variations in immune cells and functions. These rhythmic patterns impact immune responses and have implications for medical diagnostics and treatments.

Area of Science:

  • Immunology
  • Chronobiology

Background:

  • The immune system displays numerous rhythmic variations across various frequencies.
  • Circadian (approximately 24-hour) rhythms are the most studied variations within the immune system.
  • Circadian variations in peripheral blood immunocompetent cells are significant for medical diagnostics.

Purpose of the Study:

  • To explore the rhythmic variations in immune system components and functions.
  • To highlight the clinical relevance of biological rhythms in immunology.
  • To discuss the application of immune system rhythms in diagnostics and therapeutics.

Main Methods:

  • Analysis of existing literature on biological rhythms in the immune system.
  • Examination of circadian, circaseptan, and circannual variations.

  • Review of studies on humoral and cellular immunity rhythms.

    • Main Results:

    • Immune system components exhibit regular rhythmic variations at multiple frequencies.
    • Both humoral and cellular arms of the immune system function rhythmically.
    • Immune responses to antigens and challenges show circadian and other rhythmic patterns.

    Conclusions:

    • Biological rhythms are integral to immune system function.
    • Understanding these rhythms is crucial for accurate medical diagnostics.
    • Rhythmic variations in the immune system offer potential for novel therapeutic strategies.
