Eosinophils are a type of white blood cell that play a role in immune responses and help fight off infections. When these cells build up and cause inflammation in the digestive system, tissues, organs, and/or bloodstream, without a known cause, it may be the result of an eosinophil-associated disease. Join the American Partnership for Eosinophilic Disorders (APFED) for a series of conversations with researchers, clinicians, patients, and other community members as we discuss practical strategies for disease management and treatments, research, and other topics of interest.
