Membrane Fluidity in Biology, Volume 2: General Principles provides an introduction to the fundamental concepts of membrane fluidity. Key topics discussed include lateral phase separations and phase transitions; hydrophobic and electrostatic effects of membrane lipid-protein interactions; isothermal phase transitions and the effects of ionic factors; and the influence of such components as cholesterol, phospholipids, fatty acids, and cellular water on the parameters of membrane fluidity. Each of these topics is elaborated in detail to provide a unique insight into the factors influencing the thermal molecular motions of membrane components, and hence cellular membrane function. Because such ...
The aim of this book is to bring together in one volume the current research and thought on the concept of membrane fluidity as a biological phenomenon. The invited articles are intended to review recent develop ments in the areas of membrane research covered and to summarize the current concepts and theories in those areas. The authors have been given ample opportunity to present their thoughts and speculation on membrane fluidity and related phenomena in a more expanded form than is usually possible in reviews of this type. It is hoped that this approach will have a stimulating effect on research and theoretical development in the biomem brane field. The chapters in this book are arranged ...
Membrane Fluidity in Biology, Volume 3: Disease Processes focuses on the relationship of membrane lipid alterations and membrane fluidity to various pathological conditions, providing unique phenomenological conceptualizations of disease states. This book compiles comprehensive reviews on topics such as respiratory distress syndrome, diabetes and receptor function, muscular dystrophies, atherosclerosis, alcohol-membrane effects, and lymphocyte function and cancer. This publication also evaluates the interplay between membrane lipid alterations and membrane fluidity and abnormal cellular function, emphasizing how possible alterations in membrane lipids and cholesterol, and consequent changes in membrane fluidity can influence normal cellular activity and lead to pathological cellular function. This volume is intended for molecular and cellular biologists, clinician-scientists struggling with an understanding of the mechanisms of pathological processes, and biophysicists seeking research problems in pathology to study.
A thorough introduction is provided to the variety and complexity of the roles that glycoconjugates play in the cells of the nervous system. Basic information as well as the latest developments in neural glycobiology are discussed. Topics covered range from the structure and metabolism of the saccharide chains and current approaches used in their study, to changes glycoconjugates undergo during development and aging of the nervous system and the roles they have in neurological disease. The breadth and depth of topics covered make it an essential reference for those new to the field as well more seasoned investigators.
The compact myelin sheath formed around nerve axons speeds up nerve conduction and also nurtures the axon. Destruction of this sheath in demyelinating diseases such as multiple sclerosis (MS) results in nerve conduction failure and neurodegeneration. Myelin basic protein (MBP) is the second most abundant protein of central nervous system (CNS) myelin (after the proteolipid protein), representing about 30 % of the total myelin protein and about 10 % of myelin by weight. It is also present in peripheral nervous system (PNS) myelin but as a lower percentage of the total protein. This book addresses the issue of Myelin and the way it binds to negatively-charged lipids on the cytosolic surfaces of the processes and is responsible for adhesion of these surfaces of myelin in the CNS, thus forming the major dense line observed by electron microscopy.
