The year 2026 marks the centenary of the first scientific report on the hormone Relaxin by Frederick Hisaw. To celebrate this special occasion, we will be bringing together all the science and the scientists currently researching the Relaxin Family of insulin-like peptide hormones and their receptors to the University of Nottingham in the UK.

From the 2nd - 6th Aug, 2026 Nottingham will be hosting this special conference to discuss the latest developments in the evolution, physiology and pharmacology of this important family of hormones and their receptors, their roles and applications in health and disease, of importance in both clinical and veterinary medicine, as well as in model organisms.

Over 5 days, with 16 scientific sessions, including lectures, round-table discussions and poster presentations, the latest results and ideas about these hormones will be dissected and roads to implementing novel applications in therapeutics and diagnostics charted.
