The nervous system is a highly complex network of nerves that coordinates actions and sensory information by transmitting signals to and from various parts of the body. Random molecular damage that steadily accumulates with age drives the ageing process at the cellular level. Many molecular mechanisms are involved and exogenous factors, like stress, also play a role in the aging process. The nervous system at the cellular level comprises a special cell called a neuron, which transmits signals to the other cells. Many physical, chemical, or biological changes in the status of neurons characterize brain aging. It is manifested in the form of deterioration in cognitive function and dementia. Dendritic regression in pyramidal neurons, synaptic atrophy, decrease of striatal dopamine receptors, accumulation of fluorescent pigments, cytoskeletal abnormalities, and reactive astrocytes and microglia are the common features of brain aging. The consequence of molecular and cellular alterations in brain aging is characterized by a plethora of anatomical changes, such as significant neuronal loss in hippocampus and neocortex. This book provides comprehensive insights on the molecular and cellular mechanisms of aging. The readers would gain knowledge that would broaden their perspective about this area of study.

Aging of unicellular and multicellular eukaryotic organisms is a convoluted biological phenomenon, which is manifested as an age-related functional decline caused by progressive dysregulation of certain cellular and organismal processes. Many chronic diseases are associated with human aging. These aging-associated diseases include cardiovascular diseases, chronic obstructive pulmonary disease, chronic kidney disease, diabetes, osteoarthritis, osteoporosis, sarcopenia, stroke, neurodegenerative diseases (including Parkinson’s, Alzheimer’s, and Huntington’s diseases), and many forms of cancer. Studies in yeast, roundworms, fruit flies, fishes, mice, primates, and humans have provided evidence that the major aspects and basic mechanisms of aging and aging-associated pathology are conserved across phyla. The focus of this International Journal of Molecular Sciences Special Issue is on molecular and cellular mechanisms, diagnostics, and therapies and diseases of aging. Fifteen original research and review articles in this Special Issue provide important insights into how various genetic, dietary, and pharmacological interventions can affect certain longevity-defining cellular and organismal processes to delay aging and postpone the onset of age-related pathologies in evolutionarily diverse organisms. These articles outline the most important unanswered questions and directions for future research in the vibrant and rapidly evolving fields of mechanisms of biological aging, aging-associated diseases, and aging-delaying therapies.

The rapidly expanding fields of molecular and cellular neurobiology are the newest frontiers of neuroscience. This book represents the continuing efforts of the Institute of Developmental Neuroscience and Aging (IDNA) to disseminate the most recent advances on the developing and aging nervous system at the molecular and cellular levels. A group of neuroscientists presented and discussed their findings at a recent IDNA conference held in Athens, Greece, June 15-18, 1988. This meeting was sponsored by the National Hellenic Research Foundation, FIDIA, the Ministry of Research and Technology, the Tourism Organization of Greece, and the National Institute of Child Health and Human Development, NIH. The Directors of the IDNA are grateful to the local committee, Drs. Eleni Fleischer, Costas Sekeris, Michael Alexis, Theony Valcana, and Elias Kouvelas, for their efforts in organizing this meeting and for their successful integration of science and culture for the participants. This volume provides a comprehensive overview of the information presented at this conference, including in-depth discussions of each topic by the participants. The chapters are grouped into five general categories which correspond to the subject areas covered during the meeting. These include: Gene and Phenotypic Expression, Growth Factors and Oncogenes, Cytoskeletal and Extracellular Molecules, Neurotransmitters and Hormones, and Molecular Aspects of Aging and Alzheimer's Disease. The section on Gene and Phenotypic Expression includes discussions of transient gene expression in the nervous system (Herschman), developmental regulation of myelin-associated genes (Gordon et al.

This book examines the basic cellular and molecular mechanisms associated with aging. It comprehensively describes the genetic, epigenetic, biochemical and metabolic regulation of aging, as well as some important age-related diseases. Divided into two major sections, it takes readers through the various aspects of aging in a story-like manner and suggests various interventions for healthy aging, such as dietary restriction, regular exercise, nutrition and maintaining a balanced and a non-stressful lifestyle. It describes the implications of aging on the nervous system, metabolism, immunity and stem cells as well as care for the elderly. The book is an ideal companion for both new and established researchers in the field and is also useful for educators, clinicians and policy makers.

Aging represents a physiological and per se non-pathological and multifactorial process involving a set of key genes and mechanisms being triggered by different endogenous and exogenous factors. Since aging is a major risk factor in connection with a variety of human disorders, it is increasingly becoming a central topic in biochemical and medical research. The plethora of theories on aging – some of which have been discussed for decades – are neither isolated nor contradictory but instead can be connected in a network of pathways and processes at the cellular and molecular levels. This book summarizes the most prominent and important approaches, focusing on telomeres, DNA damage and oxidative stress as well as on the possible role of nutrition, the interplay between genes and environment (epigenetics) and intracellular protein homeostasis and introduces some genes that have actually extended life spans in animal models. Linking these different determinants of aging with disease, this volume aims to reveal their multiple interdependencies. We see that there is no single “perfect” theory of aging and that instead it is possible to define what the authors call the molecular aging matrix of the cell. A better knowledge of its key mechanisms and the mutual connections between its components will lead to a better understanding of age-associated disorders such as Alzheimer’s disease.

Time, Cells, and Aging, 2nd Edition presents the mechanics of cell function and the relevant implications of the molecular-genetic view to the aging phenomena. This book explores the biology of the aging process. Comprised of 11 chapters, this edition starts with an overview of the causes and mechanisms underlying the gradual deterioration of structure and function characteristics of aging. This text then examines the two aspects of the behavior of man, including the reasoned conscious behavior and the greater dependence on reaction patterns predicted on the successful responses of the past. Other chapters explore the relationship between aging and mortality rate in animals, which is a result of an organism's deceasing ability to function optimally in carrying out his vital functions. The final chapter deals with the implementation of a research plan relevant to understanding the primary mechanisms of the aging process. This book is a valuable resource for gerontologists, biologists, and molecular biologists.
