Summary

Autoimmune T cells, normally linked to disease, may actually promote tissue healing and contribute to overall health. This review explores the dual role of natural autoimmunity in the human body.

Area of Science:

  • Immunology
  • Cell Biology
  • Human Physiology

Background:

  • Autoimmunity is predominantly viewed as a pathological process underlying various diseases.
  • The human T-cell repertoire naturally contains lymphocytes with autoimmune potential.

Purpose of the Study:

  • To review existing evidence on the role of naturally occurring autoimmune T cells.
  • To explore the potential health benefits of autoimmunity, specifically in tissue repair.
  • To challenge the conventional understanding of autoimmunity as solely disease-causing.

Main Methods:

  • Literature review of studies investigating T-cell function and autoimmunity.
  • Analysis of research data on tissue repair mechanisms involving immune cells.
  • Synthesis of evidence linking autoimmune responses to physiological health benefits.

Main Results:

  • Evidence suggests that autoimmune T cells can actively participate in the healing of damaged tissues.
  • Natural autoimmunity may play a beneficial role in maintaining tissue homeostasis and repair.
  • The presence of autoimmune lymphocytes is a natural feature of the human immune system.

Conclusions:

  • Autoimmunity is not exclusively a cause of disease but can also be a cause of health.
  • Autoimmune T cells possess a previously underappreciated capacity to promote tissue regeneration.
  • A paradigm shift is needed to recognize the potential positive functions of natural autoimmunity.
