Book Description
A finely tuned regulation of gene expression is essential for shaping the nervous system and for maintaining its homeostasis throughout life. Disruptions in gene regulation can impact brain development and physiology in ways that contribute to diverse pathologies. The master orchestrators of gene activity in the nucleus are transcription factors, proteins that recognize and bind to specific DNA motifs in regulatory regions and drive changes in gene expression. Transcription factors act with the help of other co-factor proteins, including components of the Mediator complex, histone modifying enzymes, chromatin modelers, and DNA methylases. In addition, transcription factor activity in the nervous system can be modulated by extracellular signals, including growth factors, hormones, neuropeptides and neurotransmitters that activate specific receptors and intracellular transduction pathways. An in-depth understanding of the mechanisms of transcription regulation is needed in order to better describe how each element, from genes to cells, defines and maintains identities and functionalities in the healthy and diseased brain. This Research Topic is oriented to developing an integrative view about transcription regulation within the nervous system, focusing on developmental and homeostatic processes, dysregulation in functionality and expression levels and consequent associated pathologies such as neurodevelopmental disorders, brain tumors, and neurodegenerative diseases. Transcription regulation investigations will specifically focus on transcription factors that belong to the bHLH (e.g. NeuroD), homeobox (e.g. Islet, Pax, Rax, and Lhx) and CREB families, and on their roles over defined nervous system areas: cerebral cortex, thalamic and hypothalamic areas, interacting with the developing brain.

Book Description
The functional anatomy of organisms is maintained by the coordination of different systems, that often rely on particular interactions between specialized cells and between macromolecules. The immune system works with the circulatory and the lymphatic systems to protect most of the organs. However, some organs are considered immune privileged due to the presence of highly selective and regulated barriers, such as the blood-brain barrier (BBB) within the brain. The BBB controls periphery-brain molecule exchange and prevents immune effector cells from entering the homeostatic brain. BBB-associated elements, such as endothelial cells, pericytes, astrocytes, and microglia, potentially can function as antigen-presenting cells (APC). Pathological scenarios that induce dysfunction of the BBB and its associated cells may lead to the infiltration of lymphocytes crossing over from the blood to brain. Similarly, traumas can also enable B and T lymphocytes to pass bidirectionally between the CNS and the periphery, via the meningeal lymphatic vessels which drain into the cervical lymph nodes. Research in animals and in humans has revealed that B and T cells are involved in the progression of neurological diseases. It has been showed that under particular conditions, T cells establish themselves and become resident in the brain (T RM cells), from where they can either exert beneficial or detrimental effects on brain function. Amazing efforts have been made to further comprehend interactions between brain-specific cells and peripheral immune cells, and especially their roles and impact on the onset, progression, and eventual resolution of diverse brain pathologies.

Book Description
More than 18 million people in the United States have diabetes mellitus, and about 90% of these have the type 2 form of the disease. This book attempts to dissect the complexity of the molecular mechanisms of insulin action with a special emphasis on those features of the system that are subject to alteration in type 2 diabetes and other insulin resistant states. It explores insulin action at the most basic levels, through complex systems.

Book Description
This volume connects current ideas and concepts about sleep functions and circadian rhythms with the search for novel target-selective sleep-wake therapeutics. To do so, it provides a timely, state-of-the-art overview of sleep-wake mechanisms in health and disease, ongoing developments in drug discovery, and their prospects for the clinical treatment of sleep-disordered patients. It particularly focuses on the concept that sleep and wakefulness mutually affect each other, and the future therapeutic interventions with either sleep- or wake-promoting agents that are expected to not only improve the quality of sleep but also the waking behavior, cognition, mood and other sleep-associated physiological functions. The chapter 'Sleep Physiology, Circadian Rhythms, Waking Performance and the Development of Sleep-Wake Therapeutics' available open access under a CC BY 4.0 license at link.springer.com

Book Description
Recent neuroscience research makes it clear that human biology is cultural biology - we develop and live our lives in socially constructed worlds that vary widely in their structure values, and institutions. This integrative volume brings together interdisciplinary perspectives from the human, social, and biological sciences to explore culture, mind, and brain interactions and their impact on personal and societal issues. Contributors provide a fresh look at emerging concepts, models, and applications of the co-constitution of culture, mind, and brain. Chapters survey the latest theoretical and methodological insights alongside the challenges in this area, and describe how these new ideas are being applied in the sciences, humanities, arts, mental health, and everyday life. Readers will gain new appreciation of the ways in which our unique biology and cultural diversity shape behavior and experience, and our ongoing adaptation to a constantly changing world.

Book Description
Principles of Regeneration focuses on the principles, methodologies, and changes involved in the process of regeneration. The book first underscores the nature of the nucleus in Acetabularia, enzyme effects, role of ribonucleic acid in morphogenesis, and functions of the stentor. The text then takes a look at the turnover in hydroids and flatworms and regeneration blastema. Discussions focus on regeneration in hydra, interstitial cells, colonial hydroids, neoblasts, and morphogenetic fields. The publication surveys segmental addition in annelids and molting, metamorphosis, and regeneration in arthropods. The termination of regeneration, importance of nerves, morphogenesis, histogenesis of the regenerate, and role of the nerves are discussed. The manuscript also examines regeneration in fishes, amphibian limb, horns and antlers, and heads and tails. The manuscript is a dependable source of data for students of developmental biology, anatomy, and evolution, as well as teachers and researchers in biology and medicine.
