Our goal is to elucidate molecular mechanisms that determine the functional heterogeneity of different neurosecretory systems with a particular focus on synapse-like signalling mechanisms along the gut-brain-axis.
We are interested in the question how the distinct molecular and structural features of different neurosecretory systems shape their respective neurotransmitter and hormone release properties. The key goal is to understand of how these dynamic cellular processes are ultimately linked to physiology, behaviour and metabolism in health and disease.
One particular focus of our research is to dissect the molecular mechanisms that mediate the secretion of signalling substances in the gut. We aim to further understand how the cellular and neuronal circuits are organized to transmit this information with minimal delay to the brain. The initial focus is on a subset of enteroendocrine cells within the gut epithelium that respond to sensory information in the gastrointestinal tract by releasing the neurotransmitter serotonin. Altered serotonin release has been implicated in a variety of disorders and diseases including irritable bowel syndrome, inflammatory bowel diseases, and obesity. This research has received funding from the Lundbeck Foundation and from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 843494.
