The major lipid components of biological membranes can undergo many diverse and fascinating morphological rearrangements. Studies of these diverse phases and the manner in which they are formed tends to alter the properties of ordinary bilayer membranes. This book examines the structural and biological roles of lipids forming non-lamellar structures. Key Features * Characterization of non-lamellar structures * Protein activity and membrane properties * Analysis of membrane fusion * Affect of non-lamellar forming lipids on biological systems

The first volume of the Handbook deals with the amazing world of biomembranes and lipid bilayers. Part A describes all aspects related to the morphology of these membranes, beginning with the complex architecture of biomembranes, continues with a description of the bizarre morphology of lipid bilayers and concludes with technological applications of these membranes. The first two chapters deal with biomembranes, providing an introduction to the membranes of eucaryotes and a description of the evolution of membranes. The following chapters are concerned with different aspects of lipids including the physical properties of model membranes composed of lipid-protein mixtures, lateralphase separation of lipids and proteins and measurement of lipid-protein bilayer diffusion. Other chapters deal with the flexibility of fluid bilayers, the closure of bilayers into vesicles which attain a large variety of different shapes, and applications of lipid vesicles and liposomes. Part B covers membrane adhesion, membrane fusion and the interaction of biomembranes withpolymer networks such as the cytoskeleton. The first two chapters of this part discuss the generic interactions of membranes from the conceptual point of view. The following two chapters summarize the experimental work on two different bilayer systems. The next chapter deals with the process ofcontact formation, focal bounding and macroscopic contacts between cells. The cytoskeleton within eucaryotic cells consists of a network of relatively stiff filaments of which three different types of filaments have been identified. As explained in the next chapter much has been recently learned aboutthe interaction of these filaments with the cell membrane. The final two chapters deal with membrane fusion.

Biological membranes are the essential structuring elements of all living cells. Many enzymatic reactions take place at the membrane-water interface. To gain detailed insight into membrane properties, it is therefore of great importance to understand the complex nature of the interactions of membrane proteins with lipids. Lipid-Protein Interactions: Methods and Protocols provides a selection of protocols to examine protein-lipid interactions, membrane and membrane protein structure, how membrane proteins affect lipids and how they are in turn affected by the lipid bilayer and lipid properties. The methods described here are all actively used, complementary, and necessary to obtain comprehensive information about membrane structure and function. They include label-free approaches, imaging techniques and spectroscopic methodologies. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Lipid-Protein Interactions: Methods and Protocols seeks to serve both professional and novices with its wide range of the methods frequently used in this area of research.

In Bilayer Lipid Membranes. Structure and Mechanical Properties the authors use new methods of measurement, which they have themselves developed, to present an analysis of the relation between membrane structure and viscoelastic properties, in particular in the transversal direction. Hianik and Passechnik's approach is fundamentally different from the usual one, in that they analyze lipid bilayer dynamics during various modes of deformation, arriving at a new, `three-layer' model that accounts for the great heterogeneity of biomembranes. The macroscopic parameters of membranes have been measured using a wide variety of methods, leading to a discussion of the correlations between the parameters. There is also an extensive discussion of the dynamic changes in mechanical properties of lipid bilayers in the course of conformational transition of integral proteins. During the conformational changes of proteins, the structure of a bilayer undergoes a transition, reaching a new, stable membrane state. The book is the first to present a comprehensive analysis of long-distance interaction in lipid bilayers and of molecular mechanisms of mechanoreception. Audience: Scientists and graduate students working in biophysics, membranology, physiology, medicine, pharmacology, bioelectronics, electrochemistry, and colloid chemistry.

Biological membranes consisting of two main components, lipids and proteins, have many important functions in cells. Membrane structure, physical and chemical properties of lipids and proteins, and interactions between them determine membrane functions such as the barrier separating a cell from its environment, selective transport, cell recognition, signalling and compartmentalization of cellular processes. To investigate membrane structure and dynamics, and the interactions between membrane components on a molecular level, simplified artificial models of biological membranes have been developed. Various biophysical techniques are used with these models to study membrane properties and their changes under different environmental factors. This chapter describes common membrane models and some of their applications. There are two groups of models: vesicular models (micelles, bicelles and liposomes) and planar ones (lipid monolayers, supported lipid bilayers, black lipid membranes). The advantages and disadvantages of both types are discussed as well as their usefulness for particular biophysical techniques.
