Unraveling Fabry Disease: Lyso-Gb3’s Role in Gut Physiology

In this episode, coauthors Cecilia Delprete, Friederike Uhlig, Marco Caprini, and Niall P. Hyland dive into their latest research titled "Characterization of Fabry disease-associated lyso-Gb3 on mouse colonic ion transport and motility." Fabry disease (FD) is a rare genetic disorder with wide-ranging effects across the body, including the gastrointestinal (GI) system—often one of the first to show symptoms. The team explores how the lipid molecule lyso-Gb3, known to accumulate in FD, affects colonic function using ex vivo techniques like Ussing chambers and organ baths. The conversation covers key findings: lyso-Gb3 significantly alters ion transport in the colon but doesn't affect motility or nerve responses, suggesting a complex mechanism behind GI symptoms in FD patients. Could this bring us closer to understanding—and eventually treating—the GI discomfort that burdens so many with Fabry disease?
