Download or read book From Ion Channels to Cell to Cell Conversations written by Ramón Latorre and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Ion Channels written by David J. Aidley and published by Cambridge University Press. This book was released on 1996-08-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are crucial components of living cells. Situated in the cell's membranes. they allow particular ions to pass from one side of the membrane to the other. In recent years the patch clamp technique has allowed the activity of individual channels to be measured, and recombinant DNA technology has led to fascinating detail on their structure. Together, these technical advances have produced a great flowering of knowledge and understanding about the subject, itself leading to further breakthroughs in science and medicine. Ion Channels provides an introduction to this scientific endeavour. It emphasises the molecular structure of channels as determined by gene cloning technology. This knowledge illuminates discussions of the permeability and selectivity of channels, their gating and modulation, their responses to drugs and toxins and the human diseases caused when they do not function properly.

This book was released on 2006-03-30 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of articles based on some of the talks given at the Centro de Estudios Cientificos (CECS) in Valdivia during the course of a celebration to th mark the 60 birthdays of Ramon Latorre and Enrico Stefani. Ramon Latorre is one of the most outstanding figures in channel Biophysics today. The first surprise is that he trained as a Biochemist! He soon, however, became a biophysicist through his work with Guayo (Eduardo) Rojas who guided him during his Ph. D thesis in the Laboratorio de Fisiologia Celular in Montemar. His work at N.I.H with Gerald Eherenstein and Harold Lecar constitutes one of the milestones of single ion channel Biophysics. This classical work, done in planar bilayers, set the basis for understanding voltage-dependent conductances with single channel studies and predates, by many years, later studies using patch clamping techniques. Ramon was one of the firsts to find and recognize the importance of calci- activated potassium channels and to begin a detailed study of channel properties. He pioneered the ideas of voltage and calcium modulation of the open probability and he added detailed studies of gating and its modulation by other ions. Ramon is also interested in permeation and selectivity and he produced classical studies on the number of water molecules in the channel and sites occupied by barium. Results and concepts that have recently taken front page as the structure of KcSa has been described.

Download or read book Ion Channels and Plant Stress Responses written by Vadim Demidchik and published by Springer Science & Business Media. This book was released on 2010-03-15 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants live in a constantly changing environment from which they cannot physically escape. Plants therefore need signalling and response mechanisms to adapt to new local conditions. The ef?cacy of such mechanisms underlies the plant performance during stress and therefore also impacts greatly on agricultural productivity. M- ulation of ion channel activity not only provides a means for rapid signal generation 2+ but also allows adjustment of cellular physiology. For example, Ca permeable ion 2+ channels can transduce environmental stimuli into Ca -encoded messages which can modify the gene expression. Furthermore, ion channel activity is essential to control cellular ion homeostasis that impacts on plant responses to drought, salinity, pathogens, nutrient de?ciency, heavy metals, xenobiotics and other stresses. This volume focuses on the crucial roles of different types of ion channel in plant stress responses. Functions of ion channels are discussed in the context of mechanisms to relay external and endogenous signals during stress and as mechanisms to regulate cellular ion homeostasis and enzymatic activities in the context of biotic and abiotic stress. The chapters presented cover cation and anion channels located in various cellular compartments and tissues.

Download or read book Gap Junctions Molecular Basis of Cell Communication in Health and Disease written by Dale J. Benos and published by Gulf Professional Publishing. This book was released on 1999-12-14 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Intracellular Regulation of Ion Channels written by Martin Morad and published by Springer. This book was released on 1992 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the molecular processes by which ionic channels are regulated is central to the understanding of cellular function. Great advances in understanding these regulatory mechanisms have been recently achieved by the combination of several powerful techniques. Development of the patch clamp technique, ability to access the intracellular channels sites, and genetic manipulation of channel structure have allowed studies of channel function in native membranes. Cloning, sequencing and determining the channel structure and its subunits allows further insight into the regulatory mechanisms of channel function. In planning this symposium, we organized the scientific discussions around specific molecular topics independent of the tissue and species of origin. Clearly, the subject of ion channel regulation is multi-faceted, with a large number of very talented scientists working in the field. The NATO Symposium represented an attempt to bring together these individuals and synthesize and evaluate new ideas and experimental findings. A great deal of novel data was presented, and scientific insight into the molecular processes which regulate ionic channels was furthered. This book gives a synopsis of the scientific presentations and is organized into 3 sections. The first section deals with the diversity of K + channels and their regulation, including structure-function and mechanistic studies. Presentations dealt with the characterization and modulation of a variety ofK+ channels in cardiac and neuronal cells, including ATP dependent K+ channels, Na + -activated K+ channels, delayed rectifier K+ channels and the diversity of their regulation by G-proteins.

Download or read book Lectures on Quantum Gravity written by Andres Gomberoff and published by Springer Science & Business Media. This book was released on 2006-05-30 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2002 Pan-American Advanced Studies Institute School on Quantum Gravity was held at the Centro de Estudios Cientificos (CECS),Valdivia, Chile, January 4-14, 2002. The school featured lectures by ten speakers, and was attended by nearly 70 students from over 14 countries. A primary goal was to foster interaction and communication between participants from different cultures, both in the layman’s sense of the term and in terms of approaches to quantum gravity. We hope that the links formed by students and the school will persist throughout their professional lives, continuing to promote interaction and the essential exchange of ideas that drives research forward. This volume contains improved and updated versions of the lectures given at the School. It has been prepared both as a reminder for the participants, and so that these pedagogical introductions can be made available to others who were unable to attend. We expect them to serve students of all ages well.
