Neurobiology of Actin

Examining the interface between the actin cytoskeleton and the myriad issues fundamental to the understanding of the nervous system, this text covers actin's neurobiology, from its basic cellular organization and function to its roles in health and disease.

This text is an introduction to the interface between the actin cytoskeleton and the myriad of issues fundamental to the understanding of the nervous system. It covers the neurobiology of actin ranging from basic cellular organization and function to the roles of actin in the health and disease states of the nervous system. Its opening chapter presents the fundamental concepts required to appreciate the details of the molecular machinery that regulates actin in a cellular context, setting the stage for the first part of the book which reviews the neurobiology of actin at the cellular level. The latter section of the book then discusses the functions of actin in the context of neurobiological issues ranging from early development to synaptic function and disease states of the nervous system. This text is intended for neuroscientists interested in investigating the actin cytoskeleton in the context of their particular neuroscience research program, and its chapters are cross-referenced in order to assist readers in finding relevant information that is covered in greater depth in other chapters.

Introduces key issues linking the actin cytoskeleton to the nervous system Chapters are written by expert researchers and cover a wide variety of topics, starting with the process of neurulation and culminating with the regulation of synaptic function Presents topics in the context of clinically relevant issues related to the neurobiology of actin and disease states of the nervous system Includes supplementary material: sn.pub/extras

Klappentext
Neurons are characterized by a complex, dynamic and highly polarized morphology. Actin and its regulatory proteins are the most abundant set of proteins within cells, and they form one of the major cytoskeletal systemsthe actin filament cytoskeleton. While much has been learned about the roles of the actin cytoskeleton in non-neuronal cells, our understanding of the full spectrum of the functions of actin in neurons is far from complete. This book is an introduction to the interface between the actin cytoskeleton and the myriad of issues fundamental to the understanding of nervous system function. Neurobiology of Actin: From Neurulation to Synaptic Function opens with a chapter that presents the fundamental concepts required to appreciate the details of the molecular machinery that regulates actin in a cellular context, setting the stage for the first part of the book which reviews the neurobiology of actin at the cellular level. The second section of the book then discusses the functions of actin in the context of neurobiological issues ranging from early development to synaptic function and disease states of the nervous system. This text is intended for neuroscientists interested in investigating the actin cytoskeleton in the context of their particular neuroscience research program, and its chapters are cross-referenced in order to assist readers in finding relevant information that is covered in greater depth in other chapters.
