Book Description
Gap junctions are key elements in communication between cells in multicellular organisms. It is clear that their activity is essential for normal embryonic development and normal function in adult organs, although the individual roles of the proteins that form the channels (connexins) are not yet fully understood. The last few years have seen considerable progress in this field and exciting new issues concerning gap junctional intercellular communication are being raised. Perturbed gap junction activity is beginning to be linked to certain pathologies, e.g. mutations in the major connexin of the heart have been found in human patients suffering from visceroatrial heterotaxia syndrome and mutations in the gene encoding another connexin have been found in patients with Charcot-Marie-Tooth disease. This book is the first to highlight the recent progress in understanding gap junction structure and to discuss the specific roles of individual connexins. It features contributions from an interdisciplinary group of experts who review the role of gap junctions in the heart, the retina and lens, the auditory system, the reproductive system, and in cell proliferation and cancer. The book will appeal to people interested in cell and molecular biology, embryonic development, neurobiology, cardiology, gynaecology and oncology.

Book Description
Communication between cells via intercellular channels – gap junctions – appears essential to certain developmental processes and appropriate organ function. Gap Junctions in Development and Disease aims to describe the molecular events underlying impaired development and disease. Beginning with a comprehensive review of various mouse and human genes encoding the channel-forming connexins, later chapters describe several connexin mutations associated with human diseases such as hereditary deafness and female infertility. Erroneous signaling mediated by the interaction of mutant connexins with other proteins, thought to be responsible for dysfunction of organs such as heart, muscle, brain, skin, lens, placenta, and endocrine tissue in both mice and men, is also addressed. Although the question of why some mutations in gap-junction proteins lead to specific phenotypes remains to be answered, the reviews in this book provide an intriguing insight into the future direction of this research field.

Book Description
This book covers cell-cell channels at all levels of biological organization. The purpose of this book is to document that cells are not physically separated and fully autonomous units of biological life as stated by the currently valid Cell Theory. If not the cell then some lower level unit must fulfill this role. The book deals also with the identity of this elusive unit of biological life.

Book Description
Since the first gap junction protein (connexin) was cloned over a decade ago, more than a dozen connexin genes have been cloned. Consequently, a wealth of information on the molecular basis of gap junctional communication has been accumulated. This book pays tribute to this exciting era in the history of cell communication research by documenting the great strides made in this field as a result of the merging of biophysics and molecular biology, two of the most powerful approaches to studying the molecular basis of membrane channel behavior. Twenty-eight comprehensive chapters, authored by internationally recognized leaders in the field, discuss the biophysical, physiological, and molecular characteristics of cell-to-cell communication via gap junctions. Key aspects of molecular structure, formation, gating, conductance, and permeability of vertebrate and invertebrate gap junction channels are highlighted. In addition, a number of chapters focus on recent discoveries that implicate connexin mutations and alterations of gap junctional communication in the pathogenesis of several diseases, including the X-linked Charcot Marie Tooth demyelinating disease, some forms of inherited sensorineural deafness, malignant transformation, cardiac malformations and arrhythmia, eye lens cataract, and Chagas' disease.

Book Description
Cells are by nature compelled to live in groups. They develop dependence over signaling cues received from their microenvironment, in particular from other cells, whether of their own “kind” or of a different type. Therefore, communicating with these cells is a critical aspect of their behavior and fate, as they live and die normally or as they undergo disease-related pathological changes, with dramatic repercussions. In this book, we have asked expert researchers in the field of Intercellular Communication in Cancer to provide chapters on different aspects of interaction between neighboring cells, in the context of cancer diseases. We have specifically focused our efforts on membrane-to-membrane contact-based rather than growth factors-mediated modes of intercellular communications. The contributing authors provide an extensive overview of their respective area of specialization, with an in-depth discussion of the molecular mechanisms of cell-cell interactions, the impact on tumor progression and response to therapies, as well as the cancer diagnostic value of this scientific information. This book aims to introduce essential aspects of the normal and pathological cellular fate and homeostasis to both scientists and clinicians, and also to provide established researchers with an update on the novelties and future directions this expanding field is witnessing.

Book Description
Epilepsy is a devastating group of neurological disorders characterized by periodic and unpredictable seizure activity in the brain. There is a critical need for new drugs and approaches given than at least one-third of all epilepsy patients are not made free of seizures by existing medications and become "medically refractory". Much of epilepsy research has focused on neuronal therapeutic targets, but current antiepileptic drugs often cause severe cognitive, developmental, and behavioral side effects. Recent findings indicate a critical contribution of astrocytes, star-shaped glial cells in the brain, to neuronal and network excitability and seizure activity. Furthermore, many important cellular and molecular changes occur in astrocytes in epileptic tissue in both humans and animal models of epilepsy. The goal of Astrocytes and Epilepsy is to comprehensively review exciting findings linking changes in astrocytes to functional changes responsible for epilepsy for the first time in book format. These insights into astrocyte contribution to seizure susceptibility indicate that astrocytes may represent an important new therapeutic target in the control of epilepsy. Astrocytes and Epilepsy includes background explanatory text on astrocyte morphology and physiology, epilepsy models and syndromes, and evidence from both human tissue studies and animal models linking functional changes in astrocytes to epilepsy. Beautifully labelled diagrams are presented and relevant figures from the literature are reproduced to elucidate key findings and concepts in this rapidly emerging field. Astrocytes and Epilepsy is written for neuroscientists, epilepsy researchers, astrocyte investigators as well as neurologists and other specialists caring for patients with epilepsy. Presents the first comprehensive book to synthesize historical and recent research on astrocytes and epilepsy into one coherent volume Provides a great resource on the field of astrocyte biology and astrocyte-neuron interactions Details potential therapeutic targets, including chapters on gap junctions, water and potassium channels, glutamate and adenosine metabolism, and inflammation

Book Description
The importance of the developmental approach for experimental and clinical cardiology is indisputable. Clinical-epidemiological studies have clearly shown that the risk factors of serious cardiovascular diseases, such as atherosclerosis and ischemic heart disease, are already present during the early phases of ontogenetic development. Furthermore, congenital cardiovascular malformations remain the single largest cause of infant mortality from congenital defects in industrial countries. It is therefore not surprising that the interest of theoretical and clinical cardiologists in the developmental approach keeps increasing. Advances in molecular biology accelerated this trend substantially. This book is based on contributions presented at the international symposium The Developing Heart in Prague in May 2000. It is our contention that the biological, electrophysiological, morphological, functional, biochemical and functional approaches employed by distinguished scientists worldwide will provide the reader with a global picture for changes characterizing the developing heart. It should stimulate the curiosity of cardiovascular scientists in gaining insight into the mechanisms of normal and pathological development.
