Integrins are a large family of adhesion receptors involved in several pathophysiological processes and, thus, are of interest to scientists in different fields of research such as immunology and tumor and developmental biology. This book deals with the mechanisms of intracellular signaling by integrins, a very new aspect of integrin function. No books have yet been published on this topic; in this book the authors provide an organic view of the integrin signaling mechanisms through discussion of the current literature. Since the literature in this field is extremely abundant and scattered, this compilation constitutes the major value of the book. Researchers wishing to enter the field will derive most profit from this book.
