Dissecting the Molecular Mechanisms of TRPV1 Polymodal Regulation

3:30 pm to 4:30 pm
Department of Chemistry and Biochemistry Logo

Transient receptor potential (TRP) ion channels function in diverse physiological roles. Some TRP channels are directly activated by temperature. These include TRPV1 and TRPM8, which are canonical human heat and cold sensors respectively. Both channels are also relevant to pain-sensing. Despite significant clinical trials, drug discovery efforts to develop TRPV1 antagonists have generally failed due to on-target adverse effects in thermosensing and thermoregulation. Clinical failures are thought to arise from inherent polymodal regulation, where diverse mechanisms; including, temperature, chemical ligands and pH activate TRPV1. Using electrophysiology-based cellular studies coupled with temperature-dependent solution NMR spectroscopy and other biophysical tools, we’ve made progress in disentangling these mechanisms and identifying the molecular underpinnings of thermosensing. This presentation will detail our multidisciplinary efforts to understand TRP channel polymodal regulation and allosteric networks.
