TRP Channels in Sensory Transduction

TRP channels play a key role in sensory physiology and have been the focus of intensive investigation in recent years. This book is a comprehensive, detailed overview of the ways in which TRP channels are involved in a wide variety of sensory modalities.

Preface

In 1969, Cosens and Manning found a spontaneous mutation in Drosophila melanogaster that was revealed by a defect in the electroretinogram, in which the steady electrical response normally evoked by a sustained light pulse becomes transient. This impairment occurred in the receptor potential of the photoreceptor cells. For this reason, the mutant was termed Transient Receptor Potential, TRP. In 1989, Montell and Rubin cloned the gene and proposed that it encoded a novel ion channel, an idea that was confirmed in the following years by several laboratories. A second channel was also identified in the same cells by Phillips and coworkers in 1992, and was called TRP-like (TRPL), for its similarity with TRP. The first mammalian TRP channel sequence was reported independently in 1995 by the Montell and Birnbaumer laboratories, and it is known today as TRPC1, one of the seven members of the Canonical TRP (TRPC) channel subfamily, which also includes Drosophila TRP and TRPL. After the molecular cloning of TRPV1, the first member of the Vanilloid subfamily of TRP channels by David Julius and his group in 1997, our understanding of the molecular and cellular mechanisms underlying sensory transduction has made dramatic progress. Since then, a vast number of publications have accumulated in the lite
