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

The commercialization of biotechnology has resulted in an intensive search for new biological resources for the purposes of increasing food productivity, medicinal applications, energy production, and various other applications. Although biotechnology has produced many benefits for humanity, the exploitation of the planet's natural resources has also resulted in some undesirable consequences such as diminished species biodiversity, climate change, environmental contamination, and intellectual property right and patent concerns.This book discusses the role of biological, ecological, environmental, ethical, and economic issues in the interaction between biotechnology and biodiversity, using different contexts. No other book has discussed all of these issues in a comprehensive manner. Of special interest is their impact when biotechnology is shared between developed and developing countries, and the lack of recognition of the rights of indigenous populations and traditional farmers in developing countries by large multinational corporations.

Knowledge about the mechanisms of lung development has been growing rapidly, especially with regard to cellular and molecular aspects of growth and differentiation. This authoritative international volume reviews key aspects of lung development in health and disease by providing a comprehensive review of the complex series of cellular and molecular interactions required for lung development. It covers such topics as pulmonary hypoplasia, effects of malnutrition, and pulmaonary angiogenesis. An indispensable reference for all those involved in studying or treating lung disease in neonates and children, the book offers a unique view of the development of this essential organ.

This book presents state-of-the-art pre-clinical models and clinical applications of stem-cell-based therapies applied to different lung diseases, with a special focus on the translation of bench data into clinical studies. Starting with the assumption that abnormal lung tissue repair and regeneration has emerged as the driving force underlying pathogenesis and progression in many lung diseases, it sheds new light on the potential of stem/stromal cells as drivers of repair and sources of reparative factors in the lung. The first part of the book offers an overview of stem cell types and mechanisms involved in lung development, homeostasis, repair and regeneration, and reveals the crucial role of the extracellular matrix within the lung microenvironment. In the second part, leading experts present the latest pre-clinical evidence and clinical applications of stem-cell-based therapies in a wide variety of lung diseases, ranging from COPD and lung fibrosis to other rare lung diseases. The last section discusses stem cell delivery systems and devices, such as aerosolised spray application. This book appeals to pneumologists, stem cell and matrix biologists, as well as bioengeneers with a special interest in regenerative medicine applied to pulmonary 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.
