个人简介
Dr. Taché is a recognized leading expert in brain-gut interactions and the role of peptides in the underlying mechanisms of stress-related gut dysfunction and central vagal regulation of gut functon. She and her research team reported some of the pioneer work on the central actions of peptides to influence digestive function and feeding behavior. Her laboratory provided the preclinical ground work showing potential benefit of blocking corticotropin releasing signaling pathways in experimental models of irritable bowel syndrome and postoperative ileus. Building on her initial work on the peptidergic regulation of vagal activity to the gut, she is investigating with Dr. P-Q Yuan their role in the modulation of the cholinergic anti-inflammatory reflex in the context of post operative ileus. In collaboration with Dr. Lixin Wang, they demonstrated the role of ghrelin agonists to alleviate gut motor dysfunction in models of Parkinson Disease. She is directing a consortium NIH SPARC grant on the structural and functional mapping of mammalian colonic nervous system.
Research Interests
A better understanding of the brain-gut axis is of primary importance in the context of the bidirectional cross talk occurring through the autonomic nervous system and circulating hormones. There is a growing recognition that such interactions regulate digestive function, gut inflammation, and feeding behavior and can lead to the development and modulation of some gut pathophysiology. Our focus has been to delineate the signaling molecules in the brain that influence parasympathetic activity regulating gastric and colonic secretory motor function. We also assess the signaling to the brain occurring through capsaicin sensitive afferents activated by gut hormones and visceral pain. In particular, we investigate the brain and peripheral chemical coding involved under physiological conditions related to the cephalic phase and stress, and taking place in disease models of gastric erosions, postoperative ileus, irritable bowel syndrome
