Successful 12th Biennial Symposium held in Hamilton, Ontario, Canada

The world’s leading experts in the field of eosinophil research recently gathered together during the 12th Biennial Symposium of the International Eosinophil Society at the state-of-the-art David Braley Health Sciences Centre at McMaster University in Hamilton, Ontario, Canada.

The meeting featured an excellent scientific program, with 63 invited speakers delivering state-of-the-art, cutting-edge, pro/con and meet the expert presentations. In addition, over 100 abstracts were presented as oral abstracts, abstracts slams and posters. Presentations ranged from basic science to clinical, with translational research throughout. A Pre-Meeting Workshop focused exclusively on Hypereosinophilic Syndrome, talks on eosinophils and cancer, their interactions with mast cells and the microbiome, relevance to host defense, as well as eosinophil involvement in diseases such as atopic dermatitis, rhinosinusitis, and asthma made this a meeting not to be missed!

IES proudly awarded 30 young scientists with exceptional abstracts Travel Grants Awards to assist with cost of traveling to the Symposium. IES recognizes the importance of providing opportunities and engaging our Trainee Members whenever possible in order to further advance research in the fields of eosinophil biology and the pathogenesis of eosinophil-associated allergic, respiratory, gastrointestinal and other diseases.
