Lymphocyte Signal Transduction

Signal transduction through leukocyte receptors involves a variety of signaling molecules including kinases, phosphatases, adaptor proteins, small GTPases GTP exchange factors, membrane phospholipids as well as others. These signal transducers, regulated by inter- and intra-molecular interactions, as well as by various post-translational modifications, lead to the activation of transcription factors that mediate cellular differentiation and growth, effector cell functions, and apoptotic cell death. Several investigators from various parts of the world convened at the 3rd Lymphocyte Signal Transduction Workshop in Crete, Greece from May 27 to June 1, 2005 to discuss their most recent findings in leukocyte signaling. This volume represents a collection of topics discussed during the conference.

La scuola dell’atopia = The school of atopy

The need to clarify the current concepts of atopy, which for too long have oscillated between a primitive purely clinical vision and a subsequent purely immunological one, had been ripe for some time. Understanding that the role of immunoglobulins E is not exhaustive and accepting the Solomonic division between intrinsic and extrinsic atopy were the first two fundamental steps. Recent discoveries of the role of innate immunity, and therefore of antimicrobial peptides, have opened fundamental spaces for understanding in atopy and beyond. What now appears clear is that atopy is not the disease of an organ but rather a defect in the membranes that delimit our "self". The fact that these membranes are called skin, intestines, conjunctiva, bronchi or whatever has artificially fragmented the understanding and treatment of a unitary phenomenon. This book seeks to summarize the different experiences but above all to be a stimulus to ensure that medicine focuses constructively on the same target. If this is the case, we will no longer see "religious wars" between scientists and practicing doctors or, even worse, between the different specialists vying for the patient. If atopy, as we believe, is a global problem, it can only be adequately addressed in a multidisciplinary context and in a collaborative atmosphere, not only between doctor and doctor but also between doctor and patient.

Complement and Kidney Disease

It is evident that a defective or deregulated complement system results in kidney diseases. An important role of complement effector and regulatory proteins in pathological settings of the kidney has been demonstrated. A large panel of distinct human kidney diseases is caused by defective complement control. Genetic analyses have identified mutations in complement regulators that are associated with these diseases. Mutations have been identified in the fluid phase alternative pathway regulator Factor H and the membrane regulator Membrane Cofactor Protein MCP (CD46). The functional characterization of the mutant proteins allows to define the pathophysiological events on a molecular level. These new concepts and data on disease mechanisms allowed establishing new diagnostic and promising therapeutic approaches for several human kidney diseases. Molecular biology, clinics and therapy are discussed in this volume.

Cell-Cell Channels

The biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. This concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap­ parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are numerous observations which indicate that it is not the cells which serve as the basic units of biological life but that this property falls to some other, subcellular assemblage. To deal with this intricate problem concerning the fundamental unit of living matter, we proposed the so-called Cell Body concept which, in fact, devel­ ops an exceedingly original idea proposed by Julius Sachs at the end of the 19th century. In the case of eukaryotic cells, DNA-enriched nuclei are intimately associated with a microtubular cytoskeleton. In this configuration—as a Cell Body—these two items comprise the fundamental functional and struc­ tural unit of eukaryotic living matter. The Cell Body seems to be inherent to all cells in all organisms.

Cardiac Mechanotransduction

For about hundred years the investigation of heart physiology has had one central guiding principle, the "law" of Frank and Starling. This connects the return of blood into the heart and the blood pressure with cardiac con­ traction force. The "law" does it in a way that enables the cardiovascular system to react to perturbations without major malfunctions. This book is a compilation of reviews of prominent scientists on this subject. The differ­ ence of the original formulation of the Frank-Starling principle is that mechanotransduction is the central theme that leads the reader through the book. Since the discovery of the "law" the scope of topics related to this subject has broadened enormously, as can be seen easily by glancing at the contents of this book. Mechanotransduction in the heart has many faces that range from molecules to humans and their diseases.

Calcium Signalling and Disease : Molecular Pathology of Calcium

This topic is a new entry in the area of cellular calcium signaling: yet, it now spans the entire area, with discoveries that cover both genetic and acquired pathologies, even offering glimpses in the direction of therapy.Cellular calcium homeostasis, and thus calcium signalling, is mainly regulated by membrane intrinsic proteins and calcium sensor proteins. Both classes may be involved in pathological processes that affect both human and animals, ranging from common and important diseases (e.g. migraine, diabetes, epilepsia, manic depression, infertility, various types of cancer, Alzheimer’s disease, muscular dystrophy) to rare genetic conditions (e.g., a number of genetic heart conditions, autoimmune retinopathies, night blindness, hereditary amyloid polyneuropathy, malignant hyperthermia, cerebellar ataxia, atherothrombotic disease).

Axon growth and guidance

The complexarchitectureofneuronal networks togetherwith the extraordinary associated functions make the nervous system a fascinating biological structure. The considerable work performed to explore this cellular machinery is nowadays successfulbecause the mysteryofnervous system developmentisbeing unravelled. As described in their outstanding review published 10 years ago in Science.' Marc Tessier-Lavigne and Corey Goodman-the pioneers of the molecular era of axon guidance-summarized the assembly of nervous system connections as a subtle game of attraction and repulsion of neuronal growth cones. The cellular ballet ensuring the formation of billions of synapses, which ultimately gives rise to the highest cognitive functions, is primarily orchestrated by a step-by-step mechanism of growth driven by multiple molecular cues. While our general concept of axon guidance remains identical, a profound evolution ofour knowledge ofthe molecular identityofthe guidance cues together with their interactions and signalling pathways occurred over the past ten years.

Antibiotic pharmacokinetic : Pharmacodynamic considerations in the critically Ill

Provides unique insights into the issues that drive modified dosing regimens for antibiotics in the critically ill. Leading international authors provide their commentary alongside a summary of existing evidence on how to effectively dose antibiotics. Severe infection frequently necessitates admission to the intensive care unit (ICU). Equally, nosocomial sepsis often complicates the clinical course in ICU. Early, appropriate application of antibiotic therapy remains a cornerstone of effective management. However, this is challenging in the critical care environment, given the significant changes in patient physiology and organ function frequently encountered. Being cognisant of these factors, prescribers need to consider modified dosing regimens, not only to ensure adequate drug exposure, and therefore the greatest chance of clinical cure, but also to avoid encouraging drug resistance.

Alicyclobacillus : Thermophilic Acidophilic Bacilli

Soft drinks with pHs lower than 4. 0 are subjected to minimum pasteuri- tion at 65 °C for 10 min as required by the Japanese Food Sanitation Law. Not only pathogenic bacteria but most spore-forming bacteria are unable to grow at this low pH condition, and thus reports of microbial spoilage in pasteurized acidic soft drinks are rare. Since 1982, when the spoilage of aseptically packed apple juice was - tributed to a new type of acidophilic spore-forming bacteria in Germany, a succession of similar complaints regarding other fruit juice concentrates and their products has been received. In the beginning, the bacteria were classified in the genus Bacillus, but later, in 1992, the new genus Ali- clobacillus was proposed owing to their characteristic cellular membranes containing omega-alicyclic fatty acids. A group of Alicyclobacillus strains, responsible for the tainting of fruit juices, was then described as A. a- doterrestris in 1999. They are acidophilic and grow preferably at around pH 4. 0. They are thermophilic and grow better at temperatures above 40 °C. This indicates that we might have been missing them by our or- nary methods of bacterial detection at pH 7. 0 and 35 °C.

Applications of Membrane Computing

Membrane computing is a branch of natural computing which investigates computing models abstracted from the structure and functioning of living cells and from their interactions in tissues or higher-order biological structures. The models considered, called membrane systems (P systems), are parallel, distributed computing models, processing multisets of symbols in cell-like compartmental architectures. In many applications membrane systems have considerable advantages – among these are their inherently discrete nature, parallelism, transparency, scalability and nondeterminism.

Bone : Biology, harvesting, and grafting for dental implants

Dental implant placement often requires bone grafting to ensure sufficient bony support for the implants being placed. Depending on the biologic conditions of the patient, including the level of bone atrophy and the status of the remaining teeth in the mouth, more adjunctive procedures like bone harvesting or sinus grafting may be required. This book covers it all, from the biology of bone and how dental implants work within that framework to the many procedures for harvesting bone and using it to augment sites for implant placement. The different types of bone grafts and membranes are discussed as well as procedures to preserve the alveolar ridge following tooth extraction.

Liquid separations with membranes : An introduction to barrier interference

On the level of a textbook a self-consistent approach to liquid separations with membranes is presented, contrasting equilibrium separations with the rate-controlling effects of barrier interference on mass transfer. As a corollary objective, an effort is made to observe context, factual and historical, when introducing concepts and applications of membrane separation science. Ordering principle is the formal structure of mass transfer across barriers, being construed of a driving force (allocated to the condition of the mixtures to be separated) and a barrier permeability (holding the keys to membrane selectivity). The membranes, by this approach, appear by way of the mass transport demands which they are to meet, or else by way of the separation effects which they inspire.

Life - As a Matter of Fat : The Emerging Science of Lipidomics

Lipids are as important for life as proteins, sugars, and genes. The present book gives a multi-disciplinary perspective on the physics of life and the particular role played by lipids and the lipid-bilayer component of cell membranes. The book is aimed at undergraduate students and young research workers within physics, chemistry, biochemistry, molecular biology, nutrition, as well as pharmaceutical and biomedical sciences. The emphasis is on the physical properties of lipid membranes seen as soft and molecularly structured interfaces. By combining and synthesizing insights obtained from a variety of recent studies, an attempt is made to clarify what membrane structure is and how it can be quantitatively described. Furthermore, it is shown how biological function mediated by membranes is controlled by lipid membrane structure and organization on length scales ranging from the size of the individual molecule, across molecular assemblies of proteins and lipid domains in the range of nanometers, to the size of whole cells. Applications of lipids in nano-technology and biomedicine are also described.

Biophysical Aspects of Transmembrane Signaling

Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world.
