Abstract

Transient receptor potential (TRP) channels are abundantly expressed in vascular endothelium where the channels play important functional roles. In this chapter, we describe some well-established approaches, from molecular detection to functional assays, to study the role of TRP channels in endothelial cells. Comprehensive step-by-step instructions and representative figures are provided on the following methods: (1) isolation and culture of vascular endothelial cells; (2) determination of the TRP channel interaction [co-immunoprecipitation, double immunofluorescence staining, chemical cross-linking, and Förster resonance energy transfer (FRET) detection]; (3) detection of TRP channel-mediated intracellular Ca2+ changes using fluorescence microscopy; (4) determination of the electrophysiological properties by whole-cell patch clamp and examination of TRP channel function in vascular tone control using isometric tension measurement.
