Pioneer work on GLP-1 and GIP incretin hormones

Slideshow (digitally remastered) of my talk Tuesday June 20, 1995 at 10:30, at the 5th International Congress on Pancreas and Islet Transplantation (IPITA), in Miami Beach, FL (USA). My first talk at a world congress presenting the outcome of all our detailed metabolic studies in our preclinical model of canine islet autotransplantation , including our pioneer work on the incretin effects of the gut hormones GLP-1 (glucagon-like peptide-1) and GIP (Glucose-dependent Insulinotropic Polypeptide) — now, in 2025, well-known from the drugs that mimic the action of these natural hormones, to treat type 2 diabetes and obesity, by stimulating insulin release, improving blood sugar control, and reducing appetite.

May 1992 we were the first to show direct potentiation of the insulin response from isolated islets by (near-)physiological doses of both the gut hormones GLP-1 and GIP during perifusion (in vitro) of canine islets at 7.5-10 mM glucose levels (1,2), and January 1994 we next confirmed the incretin effect of a (near-)physiological dose of GLP-1 after canine islet transplantation , in a poster presented at the 13th Workshop of the AIDSPIT (aka AIDPIT) Study Group , Igls, Austria, January 23–25, 1994 (3).

Background of the work was posted earlier this year (4) and the work was published Nov 1994 in my PhD thesis Pancreatic islet transplantation , available online (5).

June 1995, 5th IPITA Talk

Tuesday June 20, 1995 at 10:30, at the 5th International Congress on Pancreas and Islet Transplantation (IPITA), in Miami Beach, FL (USA), was my first talk at a world congress presenting the outcome of all our detailed metabolic studies in the canine islet transplants , including the incretin effect of GLP-1, and also our findings with isolated canine islets during perifusion, in vitro, of the direct insulinotropic effects of the gut hormones GIP and GLP-1 (6) . That slideshow presentation (digitally remastered*) is posted here (1MEMO 20251204_1).

The proceedings paper delivered at the 5th IPITA is included in the Notes (7) , as well as the referenced previous papers (8,9)

Moments from a vibrant testimony and jazz by Simon Gronowski at the Saint-Sépulcre school in Liège, Belgium, 19 november 2013.

The Institut Saint-Sépulcre (now S2J School Center) hosted 3 sessions with Simon Gronowski that day for different age groups, including adults in the evening — and, in between, an intimate jazz moment was created in the surreal ambience of the school’s chapel.

Thanks to friends Philippe Renette (co-producer), Simon Gronowski, Koenraad Tinel (Photo Dieter Telemans featured in Die Welt , Saturday 16th Nov 2013 – Feinde wie wir, by Felix Stephan) and Patrick (assisting with sound), staff Marc Belleflamme and André Hérin, and teachers Christine Marchal, Ingrid Lothe, others, and the Saint-Sépulcre students.
Special thanks to the students Hélène, Charline, Tristan, Kimberley, Elodie, Farah, Esther, Estelle, Laetitia, Catherine, Tracy, and Pauline for making possible the unique events that month in 2013 for this Miracles film project.

Filmed by Michel van der Burg at the Station Liège-Guillemins, and Institut Saint-Sépulcre , Liège, Belgium, 19 november 2013.
