Yvette Taché, Ph.D.
Professor, Department of Medicine - Division of Digestive Diseases, at the David Geffen School of Medicine, UCLA
Director, Digestive Diseases Research Center; Director, Animal Core Head,UCLA/CURE Brain Gut Research Group
Associate Member, Cousins Center for Psychoneuroimmunology, UCLA Neuropsychiatric Institute

Research Interests

Dr. Taché’s laboratory is involved in the understanding of brain-gut interactions as it relates to the neuroanatomical substrate and biochemical coding of stress-induced alterations of gut function and viscerosensibility. She is particularly pursuing research on the role of corticotropin releasing factor (CRF) signaling pathways both in the brain and the gut in mediating gastrointestinal motor alterations and visceral hypersensitivity in response to stress exposure in collaboration with Drs. Million, Wang, and Adelson viscerosensibility.

 

She is particularly pursuing research on the role of corticotropin releasing factor (CRF) signaling pathways both in the brain and the gut in mediating gastrointestinal motor alterations and visceral hypersensitivity in response to stress exposure in collaboration with Drs. Million, Wang, and Adelson. She is also pursuing research on the implication of CRF receptors and ghrelin in immune challenge-induced alterations of gut transit and food intake. Their research relates to PNI as they are pursuing investigations on the interaction between immune mediators that activate CRF signaling pathways in both the brain and gut and gastrointestinal function along with how CRF peptides modulate mast cell activity in the gut.
