2026 marks the 20th anniversary of WIRM – a milestone that reflects two decades of scientific excellence, interdisciplinary exchange, and groundbreaking discoveries in immune regulation. Since its inception, WIRM has become a key international meeting for experts from basic and clinical immunology, translational science, and beyond. Immune regulation remains at the core of some of the most exciting developments in biomedicine. Whether it’s cancer immunotherapy, autoimmune disease, allergy, or transplantation, understanding and modulating immune responses is central to modern therapeutic strategies. WIRM 2026 will celebrate this legacy while looking ahead to the future. The congress brings together leading scientists and clinicians to present and discuss the latest insights across the full spectrum of immune regulation—from fundamental mechanisms to clinical applications. As always, WIRM combines the best of both worlds: it is large enough to encourage interdisciplinary dialogue, yet small and focused enough to facilitate direct exchange with top experts. The 2026 anniversary edition promises an especially rich and inspiring program, featuring outstanding speakers, cutting-edge science, and opportunities to reflect on the progress made—and the challenges that lie ahead. Whether you are a long-time WIRM participant or planning to join us for the first time, we warmly invite you to be part of this special event. Let’s celebrate 20 years of WIRM—and shape the next chapter of immune regulation together.
