Molecular mechanisms for reprogramming hippocampal development and function by early-life stress


Book Description

The early postnatal period is a crucial stage for hippocampal development. During this critical period, the neonatal hippocampus is highly sensitive to the detrimental consequences of adverse environmental factors. Extensive clinical and preclinical evidence has shown that traumatic events early in life have profound and persistent effects on hippocampal function and behavior. This research topic focuses on the acute and lasting effects of early-life stress on various developmental processes in the hippocampus, and aims to uncover the molecules that are responsible for early-life stress-programmed effects and underlie resilience or vulnerability to stress-related neuropsychiatric disorders later in life. We hope the articles in this research topic will provide novel insights and stimulate future studies on the mechanisms of early-life stress and brain development.




Stress Resilience


Book Description

Stress Resilience: Molecular and Behavioral Aspects presents the first reference available on the full-breadth of cutting-edge research being carried out in this field. It includes a wide range of basic molecular knowledge on the potential associations between resilience phenomenon and biochemical balance, but also focuses on the molecular and cellular mechanisms underlying stress resilience. World-renowned experts provide chapters that cover everything from the neural circuits of resilience, the effects of early-life adversity, and the transgenerational inheritance of resilience. This unique and timely book will be a go-to resource for neuroscientists and biological psychiatrists who want to improve their understanding of the consequences of stress and on how some people are able to avoid it.

Development Strategies and Biodiversity


Book Description

Development is a complex and highly dynamic process involving the cross talk among genes, maternal effects and environmental circumstances. Widespread evidence from plant to animal species show that variation in developmental conditions can modulate life history trajectories and influence key traits, such as growth, reproduction, and senescence. These effects are not limited to a single generation but can also be passed on future generations. This book aims to bring together studies of early life effects from the fields of evolutionary biology, global change biology, and biomedicine to synthesise and improve current knowledge of the mechanisms involved, and how variation in early life conditions translates into Darwinian fitness outcomes. Relying on examples of organisms’ responses to the ongoing and future environmental challenges of the Anthropocene, this book takes a novel approach to address the adaptive meaning of early life effects. The book has a broad scientific approach, targeting eco-evolutionary biologists, behavioural biologists, eco-physiologists, eco-toxicologists, as well as epidemiologists and biomedical scientists.




Neuroepigenomics in Aging and Disease


Book Description

Epigenetic mechanisms (DNA modifications, histone alterations and non-coding RNAs) are crucial for transcriptional regulation and alterations of the “physiological epigenome” are increasingly associated with human diseases. During the last decade the emerging field of neuroepigenomics have started to impact tremendously in areas such learning and memory, addiction or neurodegeneration. This expert volume covers the role of epigenetic molecular mechanism in regulation of central nervous system’s function, one of the most exciting areas of contemporary molecular neuroscience. The book describes the current knowledge on the epigenetic basis of human disease covering the complete lifespan: from neurodevelopment/childhood (Rett Syndrome, Rubinstein-Taybi, autism), adolescence (eating disorders, drug addiction, anxiety), adulthood (depression, schizophrenia, amyotrophic lateral sclerosis, Huntington’s disease) and elderly (Alzheimer’s disease, Parkinson’s disease). The book also covers the three major players on neuroepigenomic mechanisms: histones alterations, DNA modifications and non-coding RNAs, their roles at the molecular and cellular level and the impact of their alterations on neuronal function and behavior. Finally, a special chapter on state-of-the-art technologies helps the reader not only to understand epigenetic driven changes in human cognition and diseases but also the methodology that will help to generate paradigm shifts on our understanding of brain function and the role of the neuroepigenome in human diseases.




Programming HPA-axis by early life experience: Mechanisms of stress susceptibility and adaptation


Book Description

Experiences during early life program the central nervous- and endocrine-systems with consequences for susceptibility to physical and mental disorders. These programming effects depend on genetic and epigenetic factors, and their outcome leads to an adaptive or maladaptive phenotype to a given later environmental context. This Research Topic focused on the hypothalamus-pituitary-adrenal (HPA)-axis and stress-related phenotypes, and on how HPA-axis programming by the environment precisely occurs. We included original research, mini-review and review papers on a broad range of topics related to HPA-axis programming.




The APSAC Handbook on Child Maltreatment


Book Description

A resource of unparalleled thoroughness, The APSAC Handbook on Child Maltreatment, Second Edition provides critical information for those who dedicate their working lives to alleviating the causes and consequences of child abuse and neglect. Written in engaging but straightforward language and committed to immediate application, this comprehensive handbook covers physical and sexual abuse, all forms of neglect, and psychological maltreatment. Experts in a variety of specialized areas have designed each chapter to inform professionals in mental health, law, medicine, law enforcement, and child protective services of the most current empirical research and literature available as well as strategies for intervention and prevention.




The Oxford Handbook of Molecular Psychology


Book Description

This entry in the Oxford Library of Psychology compiles cutting- edge research organized around the concept "molecular psychology," which applies principles of molecular biology to the study of behavior and its neural underpinnings. Determining the biological bases for behavior, and the extent to which we can observe and explain their neural underpinnings, requires a bold, broadly defined research methodology. The interdisciplinary entries in this handbook are organized around the principle of "molecular psychology," which unites cutting-edge research from such wide-ranging disciplines as clinical neuroscience and genetics, psychology, behavioral neuroscience, and neuroethology. For the first time in a single volume, leaders in diverse research areas use molecular approaches to investigate social behavior, psychopathology, emotion, cognition and stress in healthy volunteers, patient populations, and an array of non-human species including rodents, insects, fish, and non-human primates. Chapters draw on molecular methods covering candidate genes, genome-wide association studies, copy number variations, gene expression studies, and epigenetics while addressing the ethical, legal, and social issues to emerge from this new and exciting research approach.




The Neurobiological Basis of Suicide


Book Description

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.
