Opis

Recent progress has led to a better understanding of the molecular structure of sodium channels, how they work and the mechanisms that restrict their expression to particular cell types. This book explains how these channels are modulated in various pathological states to enable the development of therapeutic strategies based on sodium channel restoration. The authors present the most current research on sodium channels and neuronal function.

• Brings together both the basic biology and biophysics with detailed consideration of the medical applications in chronic pain and epilepsy.
• Includes coverage of channelopathies, sodium channel gene expression, the modulation of sodium channels, and molecular mechanisms of gating and drug block of sodium channels.

Over the past few years there has been very important progress in the sodium channel field. We now have a good understanding of the molecular structure of these channels, of how they work, how many of them there are, and the mechanisms that restrict their expression to particular cell types. Importantly, we are beginning to understand how the expression of, and properties of these channels are modulated in various pathological states, particularly those involving neuronal hyperexcitability (such as chronic pain), and are in a position to develop therapeutic strategies based on the restoration of normal sodium channel properties. This book brings together leading researchers working on these topics to discuss recent advances in this field. Particular attention is given to the clinical applications of our knowledge of sodium channel function, especially in the fields of chronic pain and epilepsy. With broad and up–to–date coverage of this important subject, this book represents compulsory reading for basic and medical scientists with an interest in the function of sodium channels.
