Book Description
Many membranes in eukaryotic cells are inhomogeneous structures in which various membrane components are nonrandomly distributed, forming diverse types of 'domains.' Some membrane domains have long been well known, because they are sufficiently large, long-lived, and morphologically well defined to be characterized using classical microscopic and biochemical approaches. However, new technologies have revealed the presence in membranes of smaller, often highly dynamic 'nanodomains' that also play key roles in membrane function. Our current understanding of the diversity, the properties, and the functions of nanodomains is still very limited and, in some cases, controversial. Nonetheless, it is clear that many important aspects of membrane biology arise from features of membrane organization that 'play out' on spatial and temporal scales that are only now becoming experimentally accessible in living systems. In this book, we will discuss properties and interactions of membrane molecules that lead to nanodomain formation, new and emerging technologies by which nanodomains can be studied, and experimental examples that illustrate both highlights and current limitations of our present knowledge of the properties of membrane nanodomains in various cell types.

Book Description
Cell Membrane Nanodomains: From Biochemistry to Nanoscopy describes recent advances in our understanding of membrane organization, with a particular focus on the cutting-edge imaging techniques that are making these new discoveries possible. With contributions from pioneers in the field, the book explores areas where the application of these novel techniques reveals new concepts in biology. It assembles a collection of works where the integration of membrane biology and microscopy emphasizes the interdisciplinary nature of this exciting field. Beginning with a broad description of membrane organization, including seminal work on lipid partitioning in model systems and the roles of proteins in membrane organization, the book examines how lipids and membrane compartmentalization can regulate protein function and signal transduction. It then focuses on recent advances in imaging techniques and tools that foster further advances in our understanding of signaling nanoplatforms. The coverage includes several diffraction-limited imaging techniques that allow for measurements of protein distribution/clustering and membrane curvature in living cells, new fluorescent proteins, novel Laurdan analyses, and the toolbox of labeling possibilities with organic dyes. Since superresolution optical techniques have been crucial to advancing our understanding of cellular structure and protein behavior, the book concludes with a discussion of technologies that are enabling the visualization of lipids, proteins, and other molecular components at unprecedented spatiotemporal resolution. It also explains the ins and outs of the rapidly developing high- or superresolution microscopy field, including new methods and data analysis tools that exclusively pertain to these techniques. This integration of membrane biology and advanced imaging techniques emphasizes the interdisciplinary nature of this exciting field. The array of contributions from leading world experts makes this book a valuable tool for the visualization of signaling nanoplatforms by means of cutting-edge optical microscopy tools.

Book Description
Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.

Book Description
An understanding of the nervous system at virtually any level of analysis requires an understanding of its basic building block, the neuron. From Molecules to Networks provides the solid foundation of the morphologic, biochemical, and biophysical properties of nerve cells. All chapters have been thoroughly revised for this second edition to reflect the significant advances of the past 5 years. The new edition expands on the network aspects of cellular neurobiology by adding a new chapter, Information Processing in Neural Networks, and on the relation of cell biological processes to various neurological diseases. The new concluding chapter illustrates how the great strides in understanding the biochemical and biophysical properties of nerve cells have led to fundamental insights into important aspects of neurodegenerative disease. - Written and edited by leading experts in the field, the second edition completely and comprehensively updates all chapters of this unique textbook - Discusses emerging new understanding of non-classical molecules that affect neuronal signaling - Full colour, professional graphics throughout - Includes two new chapters: Information Processing in Neural Networks - describes the principles of operation of neural networks and the key circuit motifs that are common to many networks in the nervous system. Molecular and Cellular Mechanisms of Neurodegenerative Disease - introduces the progress made in the last 20 years in elucidating the cellular and molecular mechanisms underlying brain disorders, including Amyotrophic Lateral Sclerosis (ALS), Parkinson disease, and Alzheimer's disease

Book Description
In plant cells, the plasma membrane is a highly elaborated structure that functions as the point of exchange with adjoining cells, cell walls and the external environment. Transactions at the plasma membrane include uptake of water and essential mineral nutrients, gas exchange, movement of metabolites, transport and perception of signaling molecules, and initial responses to external biota. Selective transporters control the rates and direction of small molecule movement across the membrane barrier and manipulate the turgor that maintains plant form and drives plant cell expansion. The plasma membrane provides an environment in which molecular and macromolecular interactions are enhanced by the clustering of proteins in oligimeric complexes for more efficient retention of biosynthetic intermediates, and by the anchoring of protein complexes to promote regulatory interactions. The coupling of signal perception at the membrane surface with intracellular second messengers also involves transduction across the plasma membrane. Finally, the generation and ordering of the external cell walls involves processes mediated at the plant cell surface by the plasma membrane. This volume is divided into three sections. The first section describes the basic mechanisms that regulate all plasma membrane functions. The second describes plasma membrane transport activity. The final section of the book describes signaling interactions at the plasma membrane. These topics are given a unique treatment in this volume, as the discussions are restricted to the plasma membrane itself as much as possible. A more complete knowledge of the plasma membrane’s structure and function is essential to current efforts to increase the sustainability of agricultural production of food, fiber, and fuel crops.
