Autophagy Dysfunction in Alzheimer’s Disease and Dementia provides an overview for researchers and clinicians on the mechanisms involved in protein degradation in Alzheimer’s. The book discusses the implication of autophagy dysfunction in these diseases and how it causes degenerated proteins, including aggregated tau and aggregated amyloid protein. Other sections explores the possibilities of potential drug development through autophagy modulation, making this a great resource on the study of how autophagy dysfunction has been linked to the accumulation of misfolded proteins that cause death of neurons in Alzheimer’s and other neurodegenerative diseases. Discusses the implication of autophagy dysfunction in neurodegenerative diseases Highlights the mechanisms involved in protein degradation Explores the possibilities of drug development through autophagy modulation

Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.

Comprehensive overview of different aspects of autophagy as it relates to neurodegenerative diseases. The pathogenesis of the main neurodegenerative disorders includes either the accumulation of altered or misfolded proteins or exposure to several toxics. Autophagy constitute one of the two principal cellular pathways implicate in the clearance of these material and can serve as a neuroprotective mechanism. Topics include: the role of autophagy in the brain, the role of autophagy in the principal neurodegenerative disorders, and the mechanism by which different molecules cause neurotoxicity and the role autophagy plays.

What is autophagy? Why would neurons digest parts of themselves through autophagy? How can autophagy save the lives of cells under some conditions, but act as an accomplice to cell death in others? By what mechanisms are autophagy-related processes dysregulated in neurological diseases, and are there therapeutic strategies to correct or compensate for their dysfunction? This book provides an expert view of major concepts in autophagy research with a focus on autophagy in neurons. Experimental evidence for evolutionarily conserved and specialized regulatory mechanisms for autophagy in the mammalian nervous system will be presented, including recent data on braking mechanisms. Areas of intersection with cell death, the ubiquitin-proteasome system, chaperone-mediated autophagy, and the endocytic pathway will be reviewed, along with emerging areas of mitochondrial autophagy (mitophagy) and the autophagic regulation of neuritic/synaptic processes. Advances in delineating mechanisms by which autophagy is involved in the pathophysiology of neurological disorders, including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, ischemia/hypoxia and lysosomal storage diseases, will be discussed along with current drug development strategies targeting autophagy.

Autophagy is a highly regulated process that promotes vital cellular homeostasis by allowing bulk non-specific degradation of the cytoplasmic contents, mainly damaged and/or surplus organelles and proteins. Autophagy is ubiquitous in eukaryotes, highly conserved from yeast to mammals, and occurs in all mammalian tissues. Historically, autophagy was characterized as the coping response to limited energy resources (starvation), to generate additional biomolecular raw materials. However, research in the past two decades has demonstrated the indispensible roles of autophagy in eukaryotic physiology and pathology with respect to wide-ranging processes such as development, differentiation, aging, immunity, cancer biology, and neurodegenerative disorders. In this chapter, we will provide an overview of the types of autophagy and mechanisms of the autophagy pathway followed by a discussion of the current understanding of the role of autophagy in neuronal physiology, pathology of neurodegenerative disorders, and potential therapeutic approaches.
