To evaluate the emerging roles of eosinophils in immune regulation across various health and disease contexts.
Approach:
Literature Review: A critical literature review summarizing traditional and emerging functions of eosinophils.
Key Findings:
Eosinophils are involved in both pro- and anti-inflammatory responses depending on the disease context.
They play significant roles in cancer, acting as both anti-tumorigenic and pro-tumorigenic mediators.
Eosinophils are implicated in tissue repair, regeneration, and various disorders including eosinophilic gastrointestinal diseases and SARS-CoV-2.
Interpretation:
Eosinophils have a complex role in immune modulation, extending beyond traditional Th2 responses to include diverse functions in health and disease.
Limitations:
The review does not provide exhaustive coverage of all eosinophil-related diseases.
Emerging roles are still being researched and may evolve with new findings.
Conclusion:
Eosinophils are an evolutionarily conserved cell lineage with critical functions in immune networks, warranting further exploration of their roles in various diseases.
Recent CDC advisories, testing updates, and immunization recommendations highlight developments in infectious diseases, immunization, and diagnostic testing relevant to physicians across multiple specialties.
