Book Description
Cell adhesion is one of the most important properties controlling embryonic development. Extremely precise cell-cell contacts are established according to the nature of adhesion molecules that are expressed on the cell surface. The identifica tion of several families of adhesion molecules, well conserved throughout evolu tion, has been the basis of a considerable amount of work over the past 20 years that contributed to establish functions of cell adhesion in almost all organs. Nowadays, cell adhesion molecules are not just considered as cellular glue but are thought to play critical roles in cell signaling. Their ability to influence cell proliferation, mi gration, or differentiation depends on both cell surface adhesion properties and acti vation of intracellular pathways. The next challenge will be to understand how these molecules interact with each other to ensure specific functions in the morphogen esis of very sophisticated systems. Indeed, by exploring the cellular and molecular mechanisms of nervous system development, the group of H. Fujisawa in Japan identified in 1987 an adhesion molecule, neuropilin, highly expressed in the neuro pile of amphibian optic tectum. Ten years later, two groups discovered that neuropilin is a receptor for guidance signals of the semaphorin family. Axon guidance is a critical step during brain development and the mechanisms ensuring growth cone navigation are beginning to be well understood. The semaphorins are bifunctional signals defining permissive or inhibitory pathways sensed by the growth cone.

Book Description
This book is the result of the 20th International Summer School in Brain Research, organized in August 1997 in Amsterdam, by the Netherlands Institute for Brain Research at the Royal Netherlands Academy of Sciences. It is the first book that provides a complete overview of the field of neurodegeneration and regeneration including spinal cord injury, neurodegenerative diseases and therapy. Divided into five sections, the first two sections give an overview of fundamental research on nerve cell death, neuronal survival, neurite outgrowth and guidance. Extensive attention is given to the role of neurotrophins, their receptor tyrosine kinases and cell-adhesion molecules in development and regeneration of the nervous system. The third section of the book is devoted to research involving human neurodegenerative diseases and emerging treatment strategies. Section four focusses on recent advances in the understanding of pathophysiological mechanisms underlying neurodegenerative diseases, including Alzheimer's, Parkinson's and Huntington's diseases along with prion diseases. Novel insights into the neuropathological hallmarks of these diseases, as well as into transgenic animal models, the involvement of environmental factors, and genomic and mRNA changes that can cause neurodegeneration. The final section of this volume reveals recent developments in the use of cell and gene therapy to treat neurodegenerative disease and lesion-related deficits. Implantation of genetically modified cells, direct gene transfer with viral vectors and the first clinical trials with encapsulated genetically modified cells in patients suffering from amyotrophic lateral scelerosis are examples of new therapeutic strategies treating neurodegenerative diseases.The book is of particular interest to departments of neuroscience, neurological clinics and departments, the pharmalogical industry and medical libraries.

Book Description
This book covers basic research topics such as the structure-function relationships of neuropilins and mechanisms of neuropilin-mediated signal transduction, details the most important roles of the neuropilins in developmental biology, and addresses their roles in various conditions such as cancer and various eye diseases. The two neuropilin genes encode scaffold receptors that can bind several different ligands, and also associate with many other receptors and modify their activity. Further, it has been confirmed that they play important roles in the shaping of major organs and tissues such as the nervous system and the vascular system, and that they can modulate immune responses. The book offers a helpful guide for biomedical researchers and all scientists active in the neurosciences, vascular and molecular biology, as well as developmental biology and immunology.

Book Description
Tumor angiogenesis is one of the most prominent mechanisms driving tumor development and progression. This book is written by internationally renowned experts. Part 1 describes the basic mechanisms. Tumor-angiogenic signaling pathways are presented as new potential targets for anti-angiogenic therapy. Part 2 reviews the efforts made to validate new targets and to show efficacy in animals. Part 3 is devoted to the clinical development of the novel anti-angiogenic drugs and their use in clinical practice.

Book Description
Transforming growth factor-β (TGF-β) is a secreted polypeptide with multifunctional properties manifested during embryonic development, adult organ physiology, and pathobiology of major diseases, including cancer and fibrotic and cardiovascular diseases. The signaling pathway of TGF-β now is rather well understood. Continuing revelations in the mechanisms of action of TGF-β provide specific mechanistic examples of how human cells lose their controlled function and behave wrongly during the development of diverse diseases. Equally important, however, is the current promise of exploiting the TGF-β pathway in combating human disease. This book comprehensively covers major areas of human disease where the involvement of TGF-β is firmly established. Simultaneously, the book highlights major gaps in knowledge and the future directions of research that can benefit human medical science. The core set of diseases where TGF-β action is well documented and are included in the book are cancer and cardiovascular and fibrotic disorders. The central aim of the book is to stimulate young scientists to enter the prolific TGF-β field and find new solutions to the problems remaining in this area of study. For this purpose the book provides authoritative educational chapters that furnish a good introduction to the field for young doctoral students, postdocs, and clinical fellows. The book also serves as a valuable reference for the aficionados in the field, who can find accessible and well-illustrated material for their teaching and lecturing activities, via which the importance of TGF-β biology is disseminated to the world of science and to the public.

Book Description
Angiogenesis, the formation of new blood vessels, is fundamental for physiological processes such as embryonic and postnatal development, wound repair, and reproductive functions. Angiogenesis plays a major role in tumor growth and in several autoimmune and allergic disorders. Lymphangiogenesis, the formation of new lymphatic vessels, is also important for tumor growth, the formation of metastasis, and chronic inflammatory diseases. Judah Folkman, a pioneer in the study of angiogenesis, first proposed that macrophages and mast cells could be a relevant source of angiogenic factors. Since then, much effort has gone into the elucidation of the role of immune cells in the modulation of angiogenesis and lymphangiogenesis. There is now compelling evidence that several components of the innate and adaptive immune system are implicated in inflammatory and neoplastic angiogenesis and lymphangiogenesis. Articles in this volume deal with the emerging, intriguing possibility that immune cells are both a source and a target of angiogenic and lymphangiogenic factors. Therefore, cells of the immune system might play a role in inflammatory and neoplastic angiogenesis/lymphangiogenesis through the expression of several angiogenic factors and their receptors and co-receptors. The important new findings in this volume will be of special interest to vascular biologists, basic and clinical immunologists, oncologists and to specialists in allergic and immune disorders.
