Book Description
T cells play a vital role mediating adaptive immunity, a specific acquired resistance to an infectious agent produced by the introduction of an antigen. There are a variety of T cell types with different functions. They are called T cells, because they are derived from the thymus gland. This volume discusses how T cells are regulated through the operation of signaling mechanisms. Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.

Book Description
This book is about the role of calcium and calmodulin in the cell nucleus. Calcium, which is an important second messenger of signal transduction pathways, can also operate in the cell nucleus. Different calcium binding proteins, which are the targets of cellular calcium, have been identified in the nucleus of many different cell types. Prominent among these calcium binding proteins is calmodulin, which appears to be involved in the regulation of major nuclear functions such as gene expression and DNA replication.

Book Description
The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Book Description
Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.

Book Description
Environmental insults such as extremes of temperature, extremes of water status as well as deteriorating soil conditions pose major threats to agriculture and food security. Employing contemporary tools and techniques from all branches of science, attempts are being made worldwide to understand how plants respond to abiotic stresses with the aim to help manipulate plant performance that will be better suited to withstand these stresses. This book on abiotic stress attempts to search for possible answers to several basic questions related to plant responses towards abiotic stresses. Presented in this book is a holistic view of the general principles of stress perception, signal transduction and regulation of gene expression. Further, chapters analyze not only model systems but extrapolate interpretations obtained from models to crops. Lastly, discusses how stress-tolerant crop or model plants have been or are being raised through plant breeding and genetic engineering approaches. Twenty three chapters, written by international authorities, integrate molecular details with overall plant structure and physiology, in a text-book style, including key references.

Book Description
In aerobic tissues such as heart, brain, kidney, liver and brown fat, mitochon dria account for more than 20% of cell protein and play an essential role in res piration, ATP formation, ketogenesis, gluconeogenesis, amino acid metabolism, ureagenesis, thermogenesis and a variety of other metabolic activities. The mecha nisms by which these activities are integrated and regulated within the overall context of cellular physiology is of much current research interest. In order to bring together scientists examining the various diverse aspects of this overall pro blem, an International Conference on INTEGRATION OF MITOCHONDRIAL FUNC TION was held June 4-7, 1987 at the Hanes Art Center on the campus of the Uni versity of North Carolina at Chapel Hill. The chapters of this volume derive from presentations made at this conference. The focus of INTEGRATION OF MITOCHONDRIAL FUNCTION is on signifi cant new experimental and theoretical advances concerning integration of mito chondrial function at the organelle, cell, tissue and whole organism levels of organization.

Book Description
A comprehensive review of stress signaling in plants using genomics and functional genomic approaches Improving agricultural production and meeting the needs of a rapidly growing global population requires crop systems capable of overcoming environmental stresses. Understanding the role of different signaling components in plant stress regulation is vital to developing crops which can withstand abiotic and biotic stresses without loss of crop yield and productivity. Emphasizing genomics and functional genomic approaches, Protein Kinases and Stress Signaling in Plants is a comprehensive review of cutting-edge research on stress perception, signal transduction, and stress response generation. Detailed chapters cover a broad range of topics central to improving agricultural production developing crop systems capable of overcoming environmental stresses to meet the needs of a rapidly growing global population. This book describes the field of protein kinases and stress signaling with a special emphasis on functional genomics. It presents a highly valuable contribution in the field of stress perception, signal transduction and generation of responses against one or multiple stress signals. This timely resource: Summarizes the role of various kinases involved in stress management Enumerates the role of TOR, GSK3-like kinase, SnRK kinases in different physiological conditions Examines mitogen-activated protein kinases (MAPKs) in different stresses Describes the different aspects of calcium signaling under different stress conditions Examines photo-activated kinases (PAPKs) in varying light conditions Briefs the presence of tyrosine kinases in plants Highlights the cellular functions of receptor ]like protein kinases (RLKs) Possible implication of these kinases in developing stress tolerant crops Protein Kinases and Stress Signaling in Plants: Functional Genomic Perspective is an essential resource for researchers and students in the fields of plant molecular biology and signal transduction, plant responses to stress, plant cell signaling, plant protein kinases, plant biotechnology, transgenic plants and stress biology.

Book Description
A comprehensive compendium of scholarly contributions relating to bacterial virulence gene regulation. • Provides insights into global control and the switch between distinct infectious states (e.g., acute vs. chronic). • Considers key issues about the mechanisms of gene regulation relating to: surface factors, exported toxins and export mechanisms. • Reflects on how the regulation of intracellular lifestyles and the response to stress can ultimately have an impact on the outcome of an infection. • Highlights and examines some emerging regulatory mechanisms of special significance. • Serves as an ideal compendium of valuable topics for students, researchers and faculty with interests in how the mechanisms of gene regulation ultimately affect the outcome of an array of bacterial infectious diseases.
