Membranes are essential cellular organelles. They not only define cells and other organelles, but also are critical in the cell function by selectively regulating the passage of molecules by acting as a matrix for other signaling molecules, and as conduits of information transfer between the external environment and the cell interior. This series was originally added in 1970 and has since provided a systematic, comprehensive, and rigorous approach to specific topics relevant to the study of cellular membranes. Each volume is a guest edited compendium of membrane biology. This series has been a mainstay for practicing scientists and students interested in this critical field of biology. Articles covered in the volume include The Mechanical Properties of Bilayers; Molecular Dynamic Modeling of MS Channels; Structures of the Prokaryotic Mechanosensitive; Channels MscL and MscS; 3.5 Billion Years of Mechanosensory Transduction: Structure and Function of Mechanosensitive Channels in Prokaryotes; Activation of Mechanosensitive Ion Channels by Forces Transmitted through Integrins and the Cytoskeleton; Thermodynamics of Mechanosensitivity; Flexoelectricity and Mechanotransduction; Lipid Effects on Mechanosensitive Channels; Functional Interactions of the Extracellular Matrix with Mechanosensitive Channels; MSCL: The Bacterial Mechanosensitive Channel of Large Conductance; The Bacterial Mechanosensitive Channel MscS: Emerging Principles of Gating and Modulation; Structure function relations of MscS; The MscS Cytoplasmic Domain and its Conformational Changes upon the Channel Gating; Microbial TRP Channels and Their Mechanosensitivity; MSCS-Like Proteins in Plants; Delivering Force and AmplifyingSignals in Plant Mechanosensing; MS Channels in Tip Growing Systems.

This volume in the "Current Topics in Membranes" series discusses the biology of chemokines and their binding partners, chemokine receptors, in normal and disease-related states. Chemokines are small proteins that are important in normal immune responses. Recent research demonstrates a role for these proteins in a variety of diseases such as heart disease, allergy, asthma, and cancer. As a result of the discovery of this link to disease, the topic of chemokines and drugs that block their actions has become an intense are of study. This book presents the topics of chemokines, chemokine receptors, and related pathologies in an integrated manner that provides the reader with a comprehensive and up-to-date knowledge of these topics.
* Provides a comprehensive overview of the history, molecular biology, cell biology, pharmacology, physiology, and pathophysiology of chemokines and their receptors
* Each chapter discusses "future directions and unanswered questions" of chemokine biology
* Serves as a road map for future research

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.

Sodium reabsorbing epithelia play a major role in whole-body sodium homeostasis. Some examples of sodium regulating tissues include kidney, colon, lung, and sweat ducts. Sodium transport across these membranes is a two-step process: entry through an amiloride-sensitive sodium channel and exit via the ouabain-sensitive sodium/potassium ATPase. The sodium entry channels are the rate-limiting determinant for transport and are regulated by several different hormones. The sodium channels also play a significant role in a number of disease states, like hypertension, edema, drug-induced hyperkalemia, and cystic fibrosis. Amiloride-Sensitive Sodium Channels: Physiology and Functional Diversity provides the first in-depth exchange of ideas concerning these sodium channels, their regulation and involvement in normal and pathophysiological situations.
Key Features
* Summarizes current state of amiloride-sensitive sodium channel field
* Analyzes structure-function of epithelial sodium channels
* Discusses immunolocalization of epithelial sodium channels
* Examines hormonal regulation of sodium channels

Challenging and provocative overviews are presented in Volume 40 of Current Topics in Membranes. Topics on cell lipids vary from basic themes such as biosynthesis and membrane distribution to the role of lipids in intracellular signaling and membrane flow. This single volume also highlights the roles of lipids in eukaryotic cells and discusses organization of lipids in microdomains.

Membrane permeability is fundamental to all cell biology and subcellular biology. The cell exists as a closed unit. Import and export depend upon a number of sophisticated mechanisms, such as active transport, endocytosis, exocytosis, and passive diffusion. These systems are critical for the normal housekeeping physiological functions. However, access to the cell is also taken advantage of by toxic microbes (such as cholera or ptomaine) and when designing drugs.
Ernest Overton, one of the pioneers in lipid membrane research, put forward the first comprehensive theory of lipid membrane structure. His most quoted paper on the osmotic properties of cells laid the foundation for the modern concepts of membrane function, most notably important in anesthesia.
This book is designed to celebrate the centennial anniversary (in the first chapter) of Overton's work. Subsequent chapters present readers with up-to-date concepts of membrane structure and function and the challenge they pose for new explorations.
Key Features
* Provides an historical perspective of Overton's contributions to the theory of narcosis
