Описание: Early approaches towards an understanding of transport at the tonoplast of higher plant cells were based on the kinetics of radio-isotope uptake (Torii and Laties. 1966) and exchange (Pitman, 1963). A variety of other methods became available in due course (reviewed by Clarkson and Luttge, 1984). But even with the most modern developments, the function of. the tonoplast remained in the dark. On the basis of Hitchell's chemiosmotic $heory (Hitchell, 1967), mechanisms of membrane-bound H -translocating ATPases and H -solute co-transport were conceived for the plasmalemma of fungi and plants, based on experiments with intact tissues, cells or protoplasts . With the onset of the era of membrane fractionation it seemed obvious that plasmalemma and tonoplast vlould cause the greatest problems due to the apparent lack of intrinsic markers. Again the situation for the plasmalemma appeared to be favorable; the periodic-phosphotungstic-acid reagent was considered as a specific stain. There was also the opportunity to bind externally applied markers to the plasmalemma prior to cell homogenization. Vacuoles were initially considered as compartments for intracellular excretion or at best as storage compart- ments, but were later understood to have important dynamic functions in cell physiology as a lytic compart- ment comparable to animal lysosomes (Hatile, 1966). The dynamics of molecular functions of the tonoplast itself remained obscure, however, with one exception.

Описание:
Adenosine Receptors in Neurodegenerative Diseases covers the role of adenosine receptors in brain function, also focusing on related methodologies and perspectives in therapeutics. The book provides an up-to-date overview by the best specialists in the field, helping readers consider the importance of adenosine and expand the global impact and visibility of adenosine research in the CNS field.
Chapters include adenosine biology and signaling, gene regulation, control of motor function, and novel adenosine-based therapies in the CNS. It is an ideal resource for researchers, advanced graduate students, clinicians, and industry scientists working in the fields of clinical neuroscience and molecular and cellular neuroscience.

Описание: The principal objective of this symposium was to bring together investigators from all over the world who work in diverse areas of research but share a common interest in the physiologic and pathophysiologic funetions of the nueleoside adenosine. In 1978, the "International Conference on Physiological and Regulatory Funetions of Adenosine and Adenine Nueleotides," held in Banff, Canada, served as an effective catalyst in enabling scientists with differ- ent points of view to exchange information and ideas on this subject. Since 1978, the amount of research on different as peets of adenosine metabolism, mechanism of action, transport, and function in various tissues (in both nor- maI and abnormal states) has increased exponentially, and there was an urgent need for another meeting for updating information on this burgeoning subject. The focus of the meeting was extremely sharp, but the scope of the subject material was very broad. Scientists categorized as chemists, biochemists, physiologists, pharmacologists, and immunologists, working with cells and eelI fragments, with tissues such as heart, brain, musele, fat, kidney, and with human beings having immune deficiency diseases participated in the sym- posium. They had an opportunity to air their differences, reinforce their areas of agreement, and, most important, they educated each other with respeet to research on adenosine; it is hoped that they also enriched their own research programs from the information they gained from their fellow participants.
Описание: This text contains lectures which cover a range of subjects from molecular and cellular biology to clinical applications. Emphasis has been placed on information derived from studies using molecular and cellular biology techniques applied to the field of adenosine and adenine nucleotide research.

Описание: The interactions of cells with their surrounding extracellular matrix (ECM) plays a pivotal role in driving normal cell behavior, from development to tissue differentiation and function. At the cellular level, organ homeostasis depends on a productive communication between cells and ECM, which eventually leads to the normal phenotypic repertoire that characterize each cell type in the organism. A failure to establish these normal interactions and to interpret the cues emanating from the ECM is one of the major causes in abnormal development and the pathogenesis of multiple diseases. To recognize and act upon the biophysical signals that are generated by the cross talk between cells and ECM, the cells developed specific receptors, among them a unique set of receptor tyrosine kinases (RTKs), known as the Discoidin Domain Receptors (DDRs). The DDRs are the only RTKs that specifically bind to and are activated by collagen, a major protein component of the ECM. Hence, the DDRs are part of the signaling networks that translate information from the ECM, and thus they are key regulators of cell-matrix interactions. Under physiological conditions, DDRs control cell and tissue homeostasis by acting on collagen sensors; transducing signals that regulate cell polarity, tissue morphogenesis, cell differentiation, and collagen deposition. DDRs play a key role in diseases that are characterized by dysfunction of the stromal component, which lead to abnormal collagen deposition and the resulting fibrotic response that disrupt normal organ function in disease of the cardiovascular system, lungs and kidneys, just to mention a few. In cancer, DDRs are hijacked by tumor and stromal cells to disrupt normal cell-collagen communication and initiate pro-oncogenic programs. Importantly, several cancer types exhibit DDR mutations, which are thought to alter receptor function, and contribute to cancer progression. Therefore, the strong causative association between altered RTK function and disease it is been translated today in the development of specific tyrosine kinase inhibitors targeting DDRs for various disease conditions. In spite of the accumulating evidence highlighting the importance of DDRs in health and diseases, there is still much to learn about these unique RTKs, as of today there is a lack in the medical literature of a book dedicated solely to DDRs. This is the first comprehensive volume dedicated to DDRs, which will fill a gap in the field and serve those interested in the scientific community to learn more about these important receptors in health and disease.
