Download or read book Ontogeny and Phylogeny of Brain Barrier Mechanisms written by Norman R Saunders and published by Frontiers Media SA. This book was released on 2016-04-15 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain functions within an internal environment that is determined and controlled by morphological structures and cellular mechanisms present at interfaces between the brain and the rest of the body. In vertebrates these interfaces are across cerebral blood vessels (blood-brain barrier) choroid plexuses (blood-cerebrospinal fluid barrier) and pia-arachnoid. There is a CSF-brain barrier in the neuroepithelium lining the ventricular system that is only present in embryos. There is now substantial evidence that many brain barrier mechanisms develop early and that in some cases they are functionally more active and even more specialized compared to adult barriers. Therefore barriers in developing brain should be viewed as adapted appropriately for the growing brain and not, as is still widely believed, immature. Considerable advances in our understanding of these barrier mechanisms have come from studies of the developing brain and invertebrates. A striking aspect, to be highlighted in this special edition, is that many of the molecular mechanisms in these very diverse species are similar despite differences in the cellular composition of the interfaces. This Frontiers Topic comprises articles in three sections: Original studies, Reviews and Myths & Misconceptions. Original articles provide new information on molecular and cellular barrier mechanisms in developing brains of primates, including human embryos (Brøchner et al., Ek et al., Errede et al.), rodents (Bauer et al., Liddelow, Strazielle & Ghersi-Egea, Saunders et al., Whish et al.), chick (Bueno et al.) and zebrafish (Henson et al.) as well as studies in drosophila (Hindle & Bainton, De Salvo et al., Limmer et al.). The Reviews section includes evolutionary perspectives of the blood-brain and blood-CSF barriers (Bueno et al., Bill & Korzh). There are also detailed reviews of the current state of understanding of different interfaces and their functional mechanisms in developing brain (Bauer et al., Strazielle & Gjersi-Egea, Liddelow, Richardson et al., Errede et al., Henson et al., Brøchner et al) and in invertebrates (Hindle & Bainton, De Salvo et al., Limmer et al). Different aspects of the relationship between properties of the internal environment of the brain and its development are discussed. (Stolp & Molnar, Johansson, Prasongchean et al.). A neglected area, namely barriers over the surface of the brain during development is also covered (Brøchner et al.). Clinically related perspectives on barrier disruption in neonatal stroke are provided by Kratzer et al. and other aspects of dysfunction by Morretti et al. and by Palmeta et al. on the continuing problem of bilirubin toxicity. Progress in this field is hampered by many prevailing myths about barrier function, combined with methodologies that are not always appropriately selected or interpreted. These is covered in the Misconceptions, Myths and Methods section, including historical aspects and discussion of the paracellular pathway, a central dogma of epithelial and endothelial biology (Saunders et al.) and a review of markers used to define brain barrier integrity in development and in pathological conditions (Saunders et al.). Use of inappropriate markers has caused considerable confusion and unreliable interpretation in many published studies. Torbett et al deal with the complexities of the new field of applying proteomics to understanding blood-brain barrier properties as do Huntley at al with respect to applying modern high throughput gene expression methods (Huntley et al.). The Editorial summarizes the contributions from all authors. This includes mention of some the main unanswered but answerable questions in the field and what the impediments to progress may be.

Download or read book Signaling Mechanisms in Protozoa and Invertebrates written by G. Csaba and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology helps to find the roots of homeostatic regulation in organisms. In this context, many years ago a series of experiments were done, which demonstrated the hormonal regula tion also on the invertebrate level. The mechanisms are partly similar, partly different, from those found in vertebrates. The new receptor era of mammalian endocrinology stimulated research on invertebrate hormone receptors, and sophisticated methods are applied also to determine hormones. The experiments demonstrated the existence and even similar function of these structures and signaling molecules. However, data on hormones and receptors at the lowest level of metazoan life and the highest level of protozoan life were not at our disposal. About two decades ago, first observations on the presence of hormone receptors reacting to vertebrate hormones in protozoa were made. Since the early 1980s we know that hormone-like molecules similar to those of higher vertebrates are present also in unicellular organisms. The presence of some second messengers in Tetrahymena was recognized. Since then, the research has been extended and many structures - previously believed to be solely vertebrate characteristics, such as opiate receptors, similar to mammalian ones - were found in unicellular organisms. These observations justified the assumption of a complete endocrine system at protozoan level, where - considering the unicellularit- this seemed to be not required. However, it became clear that the roots of endocrine communication date back at least 2 billion years.
Download or read book Endocrinology written by S.M. McCann and published by Springer. This book was released on 2013-05-27 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: HIS book grew out of suggestions from the Publications Com T mittee of the American Physiological Society, which has planned a series covering the development of ideas about a number of areas of physiology. This was prompted by the great success of Circulation of the Blood: Men and Ideas, edited by A. P. Fishman and D. W. Richards, which was originally published in 1964 and then reissued by the Society in 1982. Three companion books are being completed in conjunction with the centennial year of the American Physiolog ical Society: this volume on endocrinology, one on the kidney, and one on membrane transport. It was our purpose not to provide a complete bibliography or a complete listing of all the progress made in a given area but to show PREFACE the principal ideas and how they developed. Consequently, limi- tions were placed on the number of references and on the length of each chapter. This book covers most of the areas of endocrinology; it is not completely comprehensive but discusses the main pathways of development and highlights the prominent investigators. We hope that the book as a whole will give an excellent picture of the evolution of this exciting area of physiology and the people involved in its growth. Most of the endocrine organs were discovered in antiquity by such early workers as Aristotle and Galen. The last endocrine gland to be discovered was the parathyroid in 1891 by Gley.

Download or read book Transgenerational Epigenetics written by Trygve Tollefsbol and published by Elsevier. This book was released on 2014-05-02 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transgenerational Epigenetics provides a comprehensive analysis of the inheritance of epigenetic phenomena between generations. Recent research points to the existence of biological phenomena that are controlled not through gene mutations, but rather through reversible and heritable epigenetic processes. Epidemiological studies have suggested that environmental factors may be heritable. In fact, environmental factors often play a role in transgenerational epigenetics, which may have selective or adverse effects on the offspring. This epigenetic information can be transferred through a number of mechanisms including DNA methylation, histone modifications or RNA and the effects can persist for multiple generations. This book examines the evolution of epigenetic inheritance, its expression in animal and plant models, and how human diseases, such as metabolic disorders and cardiovascular diseases, appear to be affected by transgenerational epigenetic inheritance. It discusses clinical interventions in transgenerational epigenetic inheritance that may be on the horizon to help prevent diseases before the offspring are born, or to reduce the severity of diseases at the very earliest stages of development in utero, and current controversies in this area of study, as well as future directions for research. Focused discussion of metabolic disorders, cardiovascular diseases and longevity, which appear most affected by reversible and heritable epigenetic processes Encompasses both foundational and clinical aspects including discussions of preventative in utero therapies Covers history, future outlook, disease management and current controversies

Download or read book Neuroendocrine Perspectives written by Eugenio E. Müller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This issue of Neuroendocrine Perspectives, Volume 9, begins with a fascinating aspect of neurobiology: the steroid control of vertebrate behavior, in this case aggressive behavior. In the first chapter, Schlinger and Callard, after an extensive historical perspective of the behavioral effects of steroid hormones, review results of their own and others' laboratories on the hormonal basis of individual and sex-related differences in the intensity ofaggressive displays in birds. These studies provide evidence that brain aromatase exerts considerable control over both sex-dependent and individual differences in aggressive behavior by controllingestrogenreceptoroccupancyinsteroid-sensitivebrainregions. A greatdeal ofattention has been devoted to psychological, socio economic and cultural factors as potential causes of drug abuse and dependence, whereas the information on the neurobiologic effects of drugs of abuse is rather scanty. Wand and Froehlich address this topic in an exhaustive chapter on the effects of ethanol on the release, synthesis and posttranslational processing of hypothalamo-hypophyseal hormones. In addition, in keeping with neurophysiological and epidemiological evidence of a genetic susceptibility to alcohol addiction, they present data to indicate how the neuroendocrine system may function as a marker for genetic susceptibility to ethanol addition.
Download or read book Phenotypic Plasticity Evolution written by David W. Pfennig and published by CRC Press. This book was released on 2021-05-31 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenotypic plasticity – the ability of an individual organism to alter its features in direct response to a change in its environment – is ubiquitous. Understanding how and why this phenomenon exists is crucial because it unites all levels of biological inquiry. This book brings together researchers who approach plasticity from diverse perspectives to explore new ideas and recent findings about the causes and consequences of plasticity. Contributors also discuss such controversial topics as how plasticity shapes ecological and evolutionary processes; whether specific plastic responses can be passed to offspring; and whether plasticity has left an important imprint on the history of life. Importantly, each chapter highlights key questions for future research. Drawing on numerous studies of plasticity in natural populations of plants and animals, this book aims to foster greater appreciation for this important, but frequently misunderstood phenomenon. Key Features Written in an accessible style with numerous illustrations, including many in color Reviews the history of the study of plasticity, including Darwin’s views Most chapters conclude with recommendations for future research
