This book is based on a series of lectures for a course on ionic channels held in Santiago, Chile, on November 17-20, 1984. It is intended as a tutorial guide on the properties, function, modulation, and reconstitution of ionic channels, and it should be accessible to graduate students taking their first steps in this field. In the presentation there has been a deliberate emphasis on the spe cific methodologies used toward the understanding of the workings and function of channels. Thus, in the first section, we learn to "read" single channel records: how to interpret them in the theoretical frame of kinetic models, which information can be extracted from gating currents in re lation to the closing and opening processes, and how ion transport through an open channel can be explained in terms of fluctuating energy barriers. The importance of assessing unequivocally the origin and purity of mem brane preparations and the use of membrane vesicles and optical tech niques in the stUGY of ionic channels are also discussed in this section. The patch-clamp technique has made it possible to study ion channels in a variety of different cells and tissues not amenable to more conven tional electrophysiological methods. The second section, therefore, deals with the use of this technique in the characterization of ionic channels in different types of cells, ranging from plant protoplasts to photoreceptors.

Ion channels generate bioelectricity. Recent findings have documented the biophysical properties, the structure, assembly and regulation, and function and dysfunction of nonclassical nervous system ion channels. This book reviews nonclassical ion channel research, ranging from the basic biology, structure, regulations to their functions not only in normal physiology but also neurological disorders, using a variety of cutting-edge techniques and novel animal models.

Ion channels allow us to see nature in all its magnificence, to hear a Bach suite, to smell the aroma of grandmother's cooking, and, in this regard, they put us in contact with the external world. These ion channels are protein molecules located in the cell membrane. In complex organisms, cells need to communicate in order to know about their metabolic status and to act in a coordinate manner. The latter is also accomplished by a class of ion channels able to pierce the lipid bilayer membranes of two adjacent cells. These intercellular channels are the functional subunits of gap junctions. Accordingly, the book is divided in two parts: the first part is dedicated to ion channels that look to the external world, and the second part is dedicated to gap junctions found at cell interfaces. This book is based on a series of symposia for a meeting on ion channels and gap junctions held in Santiago, Chile, on November 28-30, 1995. The book should be useful to graduate students taking the first steps in this field as well as a reference for the aficionado. The aim of the meeting was mainly to show the impact of various modern techniques, including cell biology, molecular biology, biophysics, and molecular genetics techniques in the study of these ubiquitous intrinsic membrane proteins. Molecular-genetics techniques paved the road to the manipulation of the channel forming molecules.

Ion channels are membrane proteins that act as gated pathways for the movement of ions across cell membranes. They play essential roles in the physiology of all cells. In recent years, an ever-increasing number of human and animal diseases have been found to result from defects in ion channel function. Most of these diseases arise from mutations in the genes encoding ion channel proteins, and they are now referred to as the channelopathies. Ion Channels and Disease provides an informative and up-to-date account of our present understanding of ion channels and the molecular basis of ion channel diseases. It includes a basic introduction to the relevant aspects of molecular biology and biophysics and a brief description of the principal methods used to study channelopathies. For each channel, the relationship between its molecular structure and its functional properties is discussed and ways in which genetic mutations produce the disease phenotype are considered. This book is intended for research workers and clinicians, as well as graduates and advanced undergraduates. The text is clear and lively and assumes little knowledge, yet it takes the reader to frontiers of what is currently known about this most exciting and medically important area of physiology. Introduces the relevant aspects of molecular biology and biophysics Describes the principal methods used to study channelopathies Considers single classes of ion channels with summaries of the physiological role, subunit composition, molecular structure and chromosomal location, plus the relationship between channel structure and function Looks at those diseases associated with defective channel structures and regulation, including mutations affecting channel function and to what extent this change in channel function can account for the clinical phenotype

Ligand and voltage-gated ion channels are highly regulated protein molecules that cross the cell membrane allowing ion flow from one side of the membrane to the other. They are ubiquitously expressed in human tissues and consist of one of the largest and best understood functional groups of proteins, with more than 400 members spanning nearly 1% of the human genome. They are involved in a variety of fundamental physiological processes, and their malfunction causes numerous diseases. In terms of the challenges faced in the effort to discover specific drugs in ancient and emerging diseases, ion channels are the third-largest class of target proteins after G-protein-coupled receptors (GPCRs) and kinases. 15% of small molecule drug targets have been reported to be voltage- or ligand-gated ion channels, resulting in approximately 150 new drug candidates in preclinical and clinical studies. Of the ion channel targeting drugs found on the market, these were identified more than a decade ago, and many of the current studies are at various stages of scientific approval. Overcoming these challenges has led the field of ion channel drug discovery to transform over the past 15 years through major advancements in genetic target detection, validation, structure-based drug design, and drug modeling of cell-based diseases.

Ion channel research has increased tremendously in the past 35 years since the first publication of the patch clamp technique by Neher and Sakmann in 1976. This is documented by the rising number of publications listed in Pubmed (http://www.ncbi.nlm.nih.gov/pubmed) including the keyword ‘ion channel’ from just 186 hits in 1976 to almost 180,000 hits today. Ion channels attract this great interest due to their pivotal role in the control of fundamental physiological processes in a plethora of different tissues. Moreover, their importance in a wide range of inherited and drug-induced pathologies spanning all major therapeutic areas makes them attractive targets for pharmacological drug screening and potential risk factors when assessing drug safety (Ashcroft, 2006; Clare, 2010; Dunlop 2008; Milligan 2009). Several methods and technologies have been developed to meet the analytical needs for studying ion channels. These approaches have addressed ion channel function directly as well as in the context of the cell and tissue. Scaling of these technologies has allowed ion channel analysis to be carried out on high throughput and high content assay systems. In this Research Topic we want to provide an up-to-date collection of the latest developments and improvements in ion channel screening; defining the cutting edge and indicating further developments required in the future.
