This volume deals with the relationships between toxins and one of the most fundamental processes in any living cell - the secretory cycle. The reader will find up-to-date information on secretion, generated by experts in this fast evolving field. In the last decade extensive molecular and cellular studies have exposed the molecular similarity among most known secretory systems. In this book secretion is discussed from its basic mode found in yeast up to its most sophisticated version in neurotransmitter release in nerve terminals. A comprehensive view on the mode of action of toxins which block secretion but also those which cause hyper-activation of exocytosis is provided. This book addresses the issue of toxin action by deciphering the molecular and cellular basis of exocytosis in various organisms and cellular contents.
Of the multitude of toxins known and the enormous variety of effects they cause, of particular interest are those that influence signal transduction. Intercellular communication by chemical signals is essential for the functioning of multicellular organisms. Many toxins exert their biological effects by interfering with the signal transduction initiated by these chemicals (hormones, transmitters, growth factors, and other mediators). Up-to-date information is provided by outstanding experts, who discuss the molecular mechanisms involved in the action of many toxins, as well as the use of toxins as informative tools with which to study signal transduction and their potential therapeutic usage...
th On behalf of the organizing committee of the 13 International Conference on Biomedical Engineering, I extend our w- mest welcome to you. This series of conference began in 1983 and is jointly organized by the YLL School of Medicine and Faculty of Engineering of the National University of Singapore and the Biomedical Engineering Society (Singapore). First of all, I want to thank Mr Lim Chuan Poh, Chairman A*STAR who kindly agreed to be our Guest of Honour to give th the Opening Address amidst his busy schedule. I am delighted to report that the 13 ICBME has more than 600 participants from 40 countries. We have received very high quality papers and inevitably we had to turndown some papers....
Here, expert scientists from industry and academia share their knowledge on the assembly of functional human tissues in vitro and how to design drug screenings predictive of human exposure. In so doing, they combine the latest technological developments with strategic outlooks, such as novel cell and tissue systems for drug screening and testing, as well as emerging in vitro culture technologies. Equally importantly, the book does not shy away from regulatory acceptance and ethical issues.
Pore-forming proteins and peptides play a central role in bacterial pathogenesis, the immune response, venomous attack, and innate immunity. Pore-forming Peptides and Protein Toxins describes how natural and synthetic peptides and toxins form pores and ionic channels that cause cell membrane collapse and cell death. Written by researchers from around the world, it discusses such topics as the channel-forming properties of Helicobacter pylori and the role of amyloid peptide channels in the development of amyloid diseases. This text provides a multidisciplinary approach to understanding the basic principles and cellular mechanisms of the actions of toxins and their potential use as research tools.
Bacteria and plants produce powerful toxins that can cause a variety of diseases, some of which are lethal for many animal species. The mechanisms of action are common to many of these toxins and represent general pathways for the interaction of a number of biomolecules with target cells, such as binding to specific surface receptors, internalizati
The inhibition of angiogenesis is an effective mechanism of slowing down tumor growth and malignancies. The process of induction or pro-angiogenesis is highly desirable for the treatment of cardiovascular diseases, wound healing disorders, etc. Efforts to understand the molecular basis, both for inhibition and induction, have yielded fascinating results. Anti-angiogenesis Drug Discovery and Development provides an excellent compilation of well-written reviews on various aspects of the anti-angiogenesis process. These reviews have been contributed by leading practitioners in drug discovery science and highlight the major developments in this exciting field in the last two decades. The feast o...
The book highlights different aspects of current understanding of neurotrophin-receptor signal transduction pathways, including the signaling endosome hypothesis. Findings on the synaptotrophic potential of NGF and related neurotrophins, neurotrophin involvement in neuronal stem cell biology, biological activity of the NGF precursor proNGF, and nociception- and antinociception-associated activity of NGF and/or BDNF are also presented and discussed. Several chapters deal with the involvement of various neurotrophins in the control of different nonneuronal processes, such as immune, inflammatory and allergic reactions, tissue repair and wound healing. The findings showed that neurotrophins pla...
Three days in Madison have thoroughly modified my view on clostridial neurotoxins. While still realizing the numerous activating, modifying and protective inputs, I cannot judge the meaningfulness of the meeting impartially. Neither may the reader expect a complete summary of all presentations. Collected in this volume, they speak for themselves without requiring an arbiter. Instead I shall write down my very personal opinions as a researcher who has studied clostridial neurotoxins for nearly 25 years. Comparable conferences have been rare during this time. A comprehensive symposium 4 on C. botulinum neurotoxins has been organized at Ft. Detrick. International conferences on tetanus have bee...
