Book Description
As the average life expectancy of many populations throughout the world increases, so to does the incidence of such age-related neurodegenerative disorders as Alzheimer's, Parkinson's, and Huntington's diseases. Rapid advances in our understanding of the molecular genetics and environmental factors that either cause or increase risk for age-related neurodegenerative disor ders have been made in the past decade. The ability to evaluate, at the cellular and molecular level, abnormalities in postmortem brain tissue from patients, when taken together with the development of valuable animal and cell-culture models of neurodegenerative disorders has allowed the identification of sequences of events within neurons that result in their demise in specific neurodegenerative disorders. Though the genetic and environmental factors that pro mote neurodegeneration may differ among disorders, shared biochemical cascades that will ultimately lead to the death of neurons have been identified. These cascades involve oxyradical production, aberrant regulation of cellular ion homeostasis and activation of a stereotyped sequence of events involving mitochondrial dysfunction and activa tion of specific proteases. Pathogenesis of Neurodegenerative Disorders provides a timely compilation of articles that encompasses fundamental mechanisms involved in neurodegenerative disorders. In addition, mechanisms that may prevent age-related neurodegenerative disorders are presented. Each chapter is written by an expert in the particular neurodegenerative disorder or mechanism or neuronal death discussed.

Book Description
"Calcium ions play a critical role in signaling in a wide variety of cells and tissues, including muscle, immune cells, neurons, the liver, and oocytes. This new volume explores the channels and pumps that transport calcium, calcium buffers and sensors, and how these produce distinct spatiotemporal signals in different circumstances. It covers calcium signaling during development and normal physiology, as well as perturbed signaling in diseases such as diabetes, neurodegeneration, and atherosclerosis"--

Book Description
MILS-13 provides an up-to-date review on the relationships between essential metals and human diseases, covering 13 metals and 3 metalloids: The bulk metals sodium, potassium, magnesium, and calcium, plus the trace elements manganese, iron, cobalt, copper, zinc, molybdenum, and selenium, all of which are essential for life. Also covered are chromium, vanadium, nickel, silicon, and arsenic, which have been proposed as being essential for humans in the 2nd half of the last century. However, if at all, they are needed only in ultra-trace amounts, and because of their prevalence in the environment, it has been difficult to prove whether or not they are required. In any case, all these elements are toxic in higher concentrations and therefore, transport and cellular concentrations of at least the essential ones, are tightly controlled; hence, their homeostasis and role for life, including deficiency or overload, and their links to illnesses, including cancer and neurological disorders, are thoroughly discussed. Indeed, it is an old wisdom that metals are indispensable for life. Therefore, Volume 13 provides in an authoritative and timely manner in 16 stimulating chapters, written by 29 internationally recognized experts from 7 nations, and supported by more than 2750 references, and over 20 tables and 80 illustrations, many in color, a most up-to-date view on the vibrant research area of the Interrelations between Essential Metal Ions and Human Diseases.

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
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 volume details our current understanding of the architecture and signaling capabilities of the B cell antigen receptor (BCR) in health and disease. The first chapters review new insights into the assembly of BCR components and their organization on the cell surface. Subsequent contributions focus on the molecular interactions that connect the BCR with major intracellular signaling pathways such as Ca2+ mobilization, membrane phospholipid metabolism, nuclear translocation of NF-kB or the activation of Bruton’s Tyrosine Kinase and MAP kinases. These elements orchestrate cytoplasmic and nuclear responses as well as cytoskeleton dynamics for antigen internalization. Furthermore, a key mechanism of how B cells remember their cognate antigen is discussed in detail. Altogether, the discoveries presented provide a better understanding of B cell biology and help to explain some B cell-mediated pathogenicities, like autoimmune phenomena or the formation of B cell tumors, while also paving the way for eventually combating these diseases.

Book Description
This book extends the original concept of the “calcium paradox” discovery, herein compiling more than 300 references in the field of calcium ion (Ca2+/cAMP) signalling pathways, neurotransmission and neurodegeneration, and neurological and psychiatric diseases. In this second edition, novel illustrations and tables (highlighting current medicines for treating these diseases, including their mechanism of action) offer improved insights into the concepts for students and clinicians. The description of other neurodegenerative diseases (Spinal muscular atrophy, Amyotrophic Lateral Sclerosis and Huntington´s disease) also adds further information with regards to treating these diseases. The growing increment in the life expectancy of the world's population has increased concern about age-related neurological diseases (neurodegenerative diseases), such as Alzheimer’s (AD) and Parkinson’s (PD) diseases, among others. It is now well-recognized that an imbalance of intracellular Ca2+ homeostasis contributes to the pathogenesis of neurological diseases like neurodegenerative diseases, including AD and PD, and others. Healthy brain aging can be promoted by regular exercise, moderation in caloric intake and engaging in intellectually challenging activities. These lifestyle factors may stabilize neuronal Ca2+ homeostasis. The discovery of the role of the “calcium paradox” due to the interaction between Ca2+ and cAMP signalling pathways (Ca2+/cAMP interaction) in neurotransmission, and neuroprotection, has subsidized the understanding of pathophysiology, and pharmacology, of the neurological and psychiatric diseases, opening a large pathway for the advancement of new pharmacological strategies for the treatment of these diseases. The proposal outlined in this book involves pharmaceuticals already approved, and may, in combination with improvements in lifestyle factors, allow sustained increments in the life quality of age-related neurological patients. Finally, this book briefly discusses other aspects of Ca2+/cAMP signalling pathways, such as their possible implications on cancer.
