Transient Receptor Potential Channels offers a unique blend of thoughtfully selected topics ranging from the structural biology of this fascinating group of ion channels to their emerging roles in human diseases. This single book covers TRP channels of yeasts, flies, fishes frogs and humans. And from the biophysics of primary thermo-sensory events in cells to the thermosensation at whole organism level, from physiology of pain to the development of pain-killers, from psychiatric illnesses to cancers, from skin cells to sperms, from taste buds to testes, from established facts to heated debates, this book contains something for every TRP enthusiasts, beginner and expert alike. It includes crucial background information, critical analysis of cutting edge research, and ideas and thoughts for numerous testable hypotheses. It also shows directions for future research in this highly dynamic field. It is a book readers will be just as eager to give to others as keep for themselves.

Thermo-TRP Channels: Biophysics of Polymodal Receptors

David Baez-Nieto, Juan Pablo Castillo, Constantino Dragicevic, Osvaldo Alvarez, and Ramon Latorre

In this chapter we discuss the polymodal activation of thermo-TRP channels using as exemplars two of the best characterized members of this class of channels: TRPM8 and TRPV1. Since channel activation by temperature is the hallmark of thermo-TRP channels, we present a detailed discussion on the thermodynamics involved in the gating processes by temperature, voltage, and agonists. We also review recently published data in an effort to put together all the pieces available of the amazing puzzle of thermo-TRP channel activation. Special emphasis is made in the structural components that allow the channel-forming proteins to integrate such diverse stimuli, and in the coupling between the different sensors and the ion conduction pathway. We conclude that the present data is most economically explained by allosteric models in which temperature, voltage, and agonists act separately to modulate channel activity.
