Book Description
Caveolae are 50-100 nm flask-shaped invaginations of the plasma membrane that are primarily composed of cholesterol and sphingolipids. Using modern electron microscopy techniques, caveolae can be observed as omega-shaped invaginations of the plasma membrane, fully-invaginated caveolae, grape-like clusters of interconnected caveolae (caveosome), or as transcellular channels as a consequence of the fusion of individual caveolae. The caveolin gene family consists of three distinct members, namely Cav-1, Cav-2 and Cav-3. Cav-1 and Cav-2 proteins are usually co-expressed and particularly abundant in epithelial, endothelial, and smooth muscle cells as well as adipocytes and fibroblasts. On the other hand, the Cav-3 protein appears to be muscle-specific and is therefore only expressed in smooth, skeletal and cardiac muscles. Caveolin proteins form high molecular weight homo- and/or hetero-oligomers and assume an unusual topology with both their N- and C-terminal domains facing the cytoplasm.

Book Description
This keenly awaited first overview of the field represents a complete guide to the structure and function of the most important mammalian cell membrane organelles. Filling a huge gap in the primary literature, this book is the first to cover the subject in detail. Following an introduction by Kai Simons, the discoverer of lipid rafts and the most prominent scientist in the field, chapters include: Historical background Distinct structures and functions Structural basis Signaling Viral entry and virion budding Cholesterol transport Caveolins Lipid shells Cell polarity and intracellular trafficking Cancer cells Of prime importance to molecular and cell biologists, biochemists, membrane scientists, cancer researchers, and virologists.

Book Description
This volume details our current understanding of the architecture and signaling capabilities of the B cell antigen receptor (BCR) in health and disease. The first chapters review new insights into the assembly of BCR components and their organization on the cell surface. Subsequent contributions focus on the molecular interactions that connect the BCR with major intracellular signaling pathways such as Ca2+ mobilization, membrane phospholipid metabolism, nuclear translocation of NF-kB or the activation of Bruton’s Tyrosine Kinase and MAP kinases. These elements orchestrate cytoplasmic and nuclear responses as well as cytoskeleton dynamics for antigen internalization. Furthermore, a key mechanism of how B cells remember their cognate antigen is discussed in detail. Altogether, the discoveries presented provide a better understanding of B cell biology and help to explain some B cell-mediated pathogenicities, like autoimmune phenomena or the formation of B cell tumors, while also paving the way for eventually combating these diseases.

Book Description
Caveolae (latin for little caves) are small structures found at the surface of cells. They are responsible for the regulation of important metabolic pathway. As a consequence, they may play a critical role in several human diseases such as atherosclerosis, cancer, diabetes, and muscular dystrophies. This book analyzes the role and function of caveolae in these aspects and serves as the first textbook currently available on caveolae/caveolin.

Book Description
INTRODUCTION AND RATIONALE FOR INTRACELLULAR CHOLESTEROL TRAFFICKING This volume is an elaboration of an earlier small meeting held in St. Louis, Missouri. In April 1997, many of the authors met for a two-day meeting devoted entirely to intracellular cholesterol trafficking. The rationale for this meeting was that investigators interested in this topic worked in a variety of fields, and rarely, if ever, all met together. Everybody knew each other's papers but mostly worked in isolation from one another. Understanding of cholesterol trafficking also appeared to have reached the point where it would start to rapidly expand beyond these few laboratories. Understanding of cholesterol trafficking was moving from a largely descriptive science into the molecular age. It seemed a good time to get together and see how much we agreed upon up to this point. More authors contributed to this volume than attended the St. Louis meeting. That meeting was generously funded by grants from Bristol-Myers Squibb, Merck and Company and Parke-Davis, however, the total funding available limited the size of the meeting. For the book, we are not so limited and have tried to be as inclusive as possible and pretty much invited everyone who is presently active in this area. We were quite fortunate to successfully recruit the authors we sought for each of these chapters. The authors and their contributions can be organized by particular interests and particular areas of expertise.

Book Description
Molecular Regulation of Endocytosis is a compilation of scientific "short stories" about the entry of external substances into cells. As one can see from the chapters, endocytosis regulates diverse processes such as homeostasis of the cell, signal transduction, entry of pathogens and viruses. In addition to the experimental techniques embedded in each chapter, entire chapters are dedicated to experimental approaches that will be useful to all scientists and their model systems. For those more clinically oriented, the final chapters look to the future and ways of utilizing endocytic pathways for therapeutic purposes.
