Autophagy in Health and Disease, Second Edition provides a comprehensive overview of the process of autophagy and its impact on human physiology and pathophysiology. It expands on the scope of the first edition by covering a wider range of cell types, developmental processes, and organ systems. The second edition is an international effort by investigators from 15 different countries whose many contributions are comprised in 28 chapters organized into six sections. The first section (Chapters 1-7) covers foundational concepts, including history, trajectory of the research field, mechanisms of autophagy, and autophagy regulation. The second section (Chapters 8-11) details developmental aspects, including stem cells, embryogenesis, hematopoiesis, and paligenosis. The subsequent sections are devoted to the role of autophagy in specific organ systems involved in metabolic control and diabetes (Chapters 12-15), the cardiovascular system (Chapters 16-18), and the nervous system (Chapters 19-20). The final section (Chapters 21-28) addresses autophagy in other organ systems vital to human health and longevity. Also included are chapters on microautophagy, chaperone-mediated autophagy, and the potential for autophagy as a therapeutic target. Autophagy in Health and Disease is invaluable to anyone new to the field as well as established investigators looking for a broader understanding of autophagy from outside their specific field of study.
