This monograph sheds new light on pulmonary sensory receptors. Diving into the pulmonary microenvironment, the book focuses on the role of pulmonary neuroepithelial bodies (NEBs) as potential receptors and effectors, able to store and release neurotransmitters. It explores NEBs as potential stem cell niche and highlights the multidisciplinary approach taken to identify and study NEBs, including functional morphological investigation, live cell imaging, genetic models, and laser microdissection combined with gene expression analysis. Complexly organized NEBs are an integral part of the intrapulmonary airway epithelium of all air-breathing vertebrates. For decades a quest has been going on to unravel the functional significance of these intriguing structures that appear to be modified in the course of many pulmonary diseases. The NEB microenvironment (ME) is composed of organoid clusters of pulmonary neuroendocrine cells (PNECs) that are able to store and release neurotransmitters and are closely contacted by extensive nerve terminals, emphasizing a potential receptor/effector role and probable signalling to the central nervous system. PNECs are largely shielded from the airway lumen by a special type of Clara cells, the Clara-like cells, with potential stem cell characteristics. So far, functional studies of the pulmonary NEB ME revealed that PNECs can be activated by various mechanical and chemical stimuli, resulting in a calcium-mediated release of neurotransmitters. In the past decades, a number of publications have exposed NEBs as potential hypoxia sensors. Recent experimental evidence unveiled that the NEB ME is a quiescent stem cell niche in healthy postnatal lungs, and silencing may involve bone morphogenetic protein signalling mediated by vagal afferents. Only an integrated approach that takes all current information into account will be able to explain the full role of the pulmonary NEB ME in health and disease. This highly informative and carefully presented book, provides insights for researchers, PhD students with an interest in (bio)medical and veterinary science, especially in the field of the autonomic innervation of the lung, chemo-and mechanoreceptors

Lung Epithelial Biology in the Pathogenesis of Pulmonary Disease provides a one-stop resource capturing developments in lung epithelial biology related to basic physiology, pathophysiology, and links to human disease. The book provides access to knowledge of molecular and cellular aspects of lung homeostasis and repair, including the molecular basis of lung epithelial intercellular communication and lung epithelial channels and transporters. Also included is coverage of lung epithelial biology as it relates to fluid balance, basic ion/fluid molecular processes, and human disease. Useful to physician and clinical scientists, the contents of this book compile the important and most current findings about the role of epithelial cells in lung disease. Medical and graduate students, postdoctoral and clinical fellows, as well as clinicians interested in the mechanistic basis for lung disease will benefit from the books examination of principles of lung epithelium functions in physiological condition. - Provides a single source of information on lung epithelial junctions and transporters - Discusses of the role of the epithelium in lung homeostasis and disease - Includes capsule summaries of main conclusions as well as highlights of future directions in the field - Covers the mechanistic basis for lung disease for a range of audiences

This book covers the identification and role of endogenous lung stem cells in health and disease, particularly the most recent advances. In addition, it discusses the rapidly growing field of stem cells and cell therapy as it relates to lung biology and disease as well as ex vivo lung bioengineering. Such approaches may provide novel therapeutic approaches for lung diseases. Human pluripotent stem cell differentiation to model the pulmonary epithelium and vasculature is also discussed. World-recognized scientists who specialize in studying both the lung epithelium and pulmonary vasculature contribute the chapters. Topics covered include: stem cell niches in the lung, the role of progenitor cells in fibrosis and asthma, iPSC in modeling lung disease, vascular repair by endothelial progenitor cells and circulating fibrocytes in pulmonary vascular remodeling. This volume of the Stem Cell Biology and Regenerative Medicine series is essential reading for researchers and clinicians interested in stem cells, lung biology and regenerative medicine. It is also an invaluable resource for advanced students studying cell biology, regenerative medicine and lung physiology.

The main objective of this book is to provide a comprehensive review on stem cells and their role in tissue regeneration, homeostasis and therapy. In addition, the role of cancer stem cells in cancer initiation, progression and drug resistance are discussed. The cell signaling pathways and microRNA regulating stem cell self-renewal, tissue homeostasis and drug resistance are also mentioned. Overall, these reviews will provide a new understanding of the influence of stem cells in tissue regeneration, disease regulation, therapy and drug resistance in several human diseases.

Arterial chemoreceptors are unique structures which continuously monitor changes in arterial blood oxygen, carbon dioxide, glucose, and acid. Alterations in these gases are almost instantaneously sensed by arterial chemoreceptors and relayed into a physiological response which restores blood homeostasis. Arterial Chemoreception contains updated material regarding the physiology of the primary arterial chemoreceptor; the carotid body. Moreover, this book also explores tantalizing evidence regarding the contribution of the aortic bodies, chromaffin cells, lung neuroepithelial bodies, and brainstem areas involved in monitoring changes in blood gases. Furthermore this collection includes data showing the critical importance of these chemoreceptors in the pathophysiology of human disease and possible therapeutic treatments. This book is a required text for any researcher in the field of arterial chemoreception for years to come. It is also a critical text for physicians searching for bench-to-bedside treatments for heart failure, sleep apnea, and pulmonary hypertension.
