Opis: The Functions, Disease-Related Dysfunctions, and Therapeutic Targeting of Neuronal Mitochondria - Marie Hardwick

This book presents advances in the field of neuronal mitochondria functions, relation to therapeutics, and pharmacology. For scientists and researchers in both industry and academia, this book provides detailed discussion, examples, and approaches, to illustrate the potential of mitochondria as therapeutic targets for neuronal diseases. Helps readers understand the regulation of mitochondrial cellular processes, such as substrate metabolism, energy production, and programmed versus sporadic cell death Offers insights on the development of strategies for targeted therapeutic approaches and potential personalized treatments Includes examples of mitochondrial drugs, development, and mitochondria-targeted approaches for more efficient treatment methods and further developments in the field Covers the model systems and approaches needed for the development of new drugs for the central nervous system to provide potential modern therapeutics for neurodegenerative disordersContributors xiv Preface xviii Section I Mitochondrial Structure and Ion Channels 1 1 Mitochondrial Permeability Transition: A Look From a Different Angle 3 Nickolay Brustovetsky 1.1 Regulation of Intracellular Calcium in Neurons 3 1.2 Calcium Overload and Mitochondrial Permeability Transition 4 1.3 The Mitochondrial Transition Pore 8 1.3.1 Evidence for ANT and VDAC as Components of the PTP 8 1.3.2 Alternative Hypotheses of mPTP Composition 17 Acknowledgments 22 References 22 2 The Mitochondrial Permeability Transition Pore, the c ]Subunit of the F1FO AT P Synthase, Cellular Development, and Synaptic Efficiency 31 Elizabeth A.
