Adult Neurogenesis: Beyond Rats and Mice
Researchers working on adult neurogenesis have focused largely on inbred laboratory rodents. While this provides a strong advantage of restricting genetic variation in the group, it also narrows our perspective on adult neurogenesis as a biological phenomenon. Many unsolved issues and open questions cannot be resolved without the contribution of comparative studies spanning through widely different species: how did adult neurogenesis evolve, what is the link between adult neurogenesis and brain complexity, how do adult neurogenesis and animal behavior influence each other, how does adult neurogenesis contribute to brain plasticity, cognition and, possibly, repair, and how do experimental conditions affect adult neurogenesis. The main message from the comparative approach to adult neurogenesis is that the relative exclusive focus on laboratory rodents can result in a bias on how we think about this biological process.
Neural Stem Cells
Twenty years after the discovery of neural stem cells, the question whether the central nervous system can be considered among regenerative tissues is still open. On one side, deep characterization of neural stem and progenitor cells, their niches, and their progeny in brain neurogenic sites overtly showed that new neurons can be generated in the brain of adult mammals, including humans. On the other side, many problems arise when stem cells encounter the mature brain parenchyma, still hampering the development of efficacious therapeutic approaches with endogenous or exogenously-delivered neural stem cells. This book tries to make the point on these extremely promising, yet unresolved, issues.
Adult neurogenesis twenty years later: physiological function versus brain repair
The discovery that mammalian brains contain neural stem cells which perform adult neurogenesis - the production and integration of new neurons into mature neural circuits - has provided a fully new vision of neural plasticity. On a theoretical basis, this achievement opened new perspectives for therapeutic approaches in restorative and regenerative neurology. Nevertheless, in spite of striking advancement concerning the molecular and cellular mechanisms which allow and regulate the neurogenic process, its exploitation in mammals for brain repair strategies remains unsolved. In non-mammalian vertebrates, adult neurogenesis also contributes to brain repair/regeneration. In mammals, neural stem cells do respond to pathological conditions in the so called "reactive neurogenesis", yet without substantial regenerative outcome. Why, even in the presence of stem cells in the brain, we lack an effective reparative outcome in terms of regenerative neurology, and which factors hamper the attainment of this goal? Essentially, what remains unanswered is the question whether (and how) physiological functions of adult neurogenesis in mammals can be exploited for brain repair purposes.
Crosstalk between the osteogenic and neurogenic stem cell niches: how far are they from each other?
Somatic stem cells reside in definite compartments, known as "niches", within developed organs and tissues, being able to renew themselves, differentiate and ensure tissue maintenance and repair. In contrast with the original dogmatic distinction between renewing and non-renewing tissues, somatic stem cells have been found in almost every human organism, including brain and heart. (HSCs) and mesenchymal stem cells (MSCs), that intensely interacts. HSCs represent the common precursors of all mature blood cells. (Bone, cartilage, blood vessels, adipose tissue, and.), And in the case of the skeletal muscle Supporting connective stroma). Despite this high plasticity, the claim that MSCs could be...
Mechanisms of Neuronal Migration during Corticogenesis
The cerebral cortex plays central roles in many higher-order functions such as cognition, language, consciousness, and the control of voluntary behavior. These processes are performed by the densely interconnected networks of excitatory pyramidal neurons and inhibitory interneurons, and the balanced development of these two types of neuron is quite important. During cortical development, pyramidal neurons and interneurons show quite different migratory behaviors: radial migration and tangential migration, respectively. Pyramidal neurons are generated in the ventricular zone of the dorsal telencephalon, and migrate radially along radial glial fibers toward the pial surface, forming a six-laye...
Tumors of the Central Nervous System, Volume 9
The ninth volume in this essential series discusses key advances in our understanding of neoplasms in the human central nervous system. This publication deals with various aspects of nine separate types of brain tumors. With 70 contributors from 17 nations, this edition offers an unrivalled thoroughness and breadth of coverage that includes the very latest research results on the following tumor types: astrocytoma, lymphoma, supratentorial and glioneuronal tumors, gangliogliomas, neuroblastoma in adults, hemangioma, and ependymoma. The content introduces new technologies and their applications in diagnosis, treatment and therapy of tumors. It explains molecular profiling techniques that enable oncologists to select appropriate therapies for clinical trials, and discusses a number of surgical treatments, including resection and radiosurgery. Volume 9 is interspersed with color illustrations and tables depicting many of the results. This volume joins its fellow publications in a valuable series that fully explores controversies and debates in CNS cancer therapy, and furthers the scientific quest for effective therapies to combat cancer in all its forms.
Multilateral Cooperation in Tax Law
An in-depth analysis of various aspects of multilateral cooperation in tax law Tax evasion and aggressive tax planning causing base erosion and profit shifting (BEPS) has been a widely discussed topic among academics and tax policy makers over the past decades. Increasing globalization and digitalization have contributed to the intensification of this issue in recent years. At the same time, states continue to largely insist on their sovereignty in the area of tax law. However, due to their cross-border nature, issues related to BEPS are shared problems among the states and can typically not be solved by a single nation. Therefore, multilateral cooperation represents an option to build a bri...
50th Anniversary of Adult Neurogenesis: Olfaction, Hippocampus and beyond
In the mid-sixties, the discovery by Altman and co-workers of neurogenesis in the adult brain changed the previous conception of the immutability of this organ during adulthood sustained among others by Cajal. This discovery was ignored up to eighty’s when Nottebohm demonstrated neurogenesis in birds. Subsequently, two main neurogenic zones were characterized: the subventricular zone of the lateral ventricle and the subgranular layer of the dentate gyrus. Half century later, the exact role of new neurons in the adult brain is not completely understand. This book is composed by a number of articles by leaders in the filed covering from an historic perspective to potential therapeutic opportunities.
