This book aims to provide a guide to researchers on how to work with Transient Receptor Potential (TRP) channels, describing current methodologies and protocols, and highlighting the challenges ahead that will require the development of new technologies. Articles cover a wide range of techniques, from structure to function, concluding with how to best to evaluate some of the in vivo function of TRP channels, particularly in regard to their involvement in hyperalgesia and allodynia. Also, the collection describes important and inspiring available tools that are currently being used to investigate the activity of these channels in vitro and in vivo in terms of their underlying protein structure, segueing into dealing with the generation of pharmacological tools to explore their in vivo activity and their involvement in cellular signaling pathways, which may be developed into drugs to treat diseases caused by channel dysfunction or hyperactivity. Written for the highly successful Methods in Molecular Biology series, chapters include the necessary detail and implementation advice to ensure successful results in the lab.
