Eosinophils, once thought only to fight parasites, are now known to drive inflammation in conditions like urticaria. Understanding eosinophil recruitment and activation offers new therapeutic targets for difficult-to-treat hives.

Area of Science:

  • Immunology
  • Dermatology

Background:

  • Eosinophils were traditionally viewed as mediators of anti-helminthic defense.
  • Emerging evidence highlights their significant role in immune regulation and inflammatory reactions.

Purpose of the Study:

  • To elucidate the mechanisms of eosinophil recruitment and activation in urticaria.
  • To discuss the contribution of eosinophils to inflammation and immune regulation in urticarial conditions.

Main Methods:

  • Review of existing literature on eosinophil biology and their role in inflammatory diseases.
  • Analysis of factors influencing eosinophil tissue-specific recruitment and activation pathways.

Main Results:

  • Eosinophils are implicated in the pathogenesis of urticaria, contributing to chronic inflammation.

  • Their activation involves diverse membrane receptors and the release of potent mediators.

    • Conclusions:

    • Eosinophils play a critical role in the pathophysiology of urticaria.
    • Targeting eosinophil pathways may lead to novel treatments for antihistamine-resistant urticaria.
