Book Description
This first book to cover neural development, neuronal survival and function on the genetic level outlines promising approaches for novel therapeutic strategies in fighting neurodegenerative disorders, such as Alzheimer's disease. Focusing on transcription factors, the text is clearly divided into three sections devoted to transcriptional control of neural development, brain function and transcriptional dysregulation induced neurological diseases. With a chapter written by Nobel laureate Eric Kandel, this is essential reading for neurobiologists, geneticists, biochemists, cell biologists, neurochemists and molecular biologists.

Book Description
Immediate-early genes are believed to be involved in the neuron's ability to con vert short-term synaptic stimulation into long-lasting responses and thus contribute to the adaptive alterations involved in neuronal plasticity. Cellular immediate-early genes share a close structural homology with some viral oncogenes. Recent advances in cellular biology have identified the activation and deactivation of immediate-early genes as molecular mechanisms to control regulated and deregulated growth, cellular differentiation and development. In this view immediate-early genes may function as third messengers in a stimulus transcription cascade transferring extracellular information into changes in target gene transcription, thereby changing the phenotype of neurons. Immediate-Early Genes in the Central Nervous System provides a comprehensive up-to-date overview of current methodology in the research of immediate-early genes and includes a wide range of neurobiological topics, such as regeneration, memory formation, epilepsia and nociception. The contributors to this book have been selected from among the leading experts in their field of research. T.R. TOLLE J. SCHADRACK W.

Book Description
The central nervous system is the most complex and highly organized tissue in animals; composed of thousands of neurites connected in specific and highly reproducible ways. My thesis research has focused on the generation of neuronal diversity: specifically how neurons adopt individual, often unique, identities. Work in many labs has revealed that a large set of transcription factors act in combinatorial manner to specify the fate of individual neurons or small groups of neurons. However, in most cases, it remains unclear how individual or specific combinations of transcription factors directly control the terminal differentiation of neurons via the regulation of different genes, such as neurotransmitters. My thesis work has focused on the identification and characterization of new members of the combinatorial code of transcription factor and on initial attempts to link these transcription factors to the expression and activity of genes that contribute directly to neuronal differentiation. In chapter 2, I describe the identification and characterization of Dbx, a homedomain-containing transcription factor, expressed in a mixture of progenitor cells and a subset of GABAergic interneurons. I show that Dbx is expressed in many interneurons that are sibling to motor neurons, and that Dbx is required to promote the development of these interneurons via cross-repressive interactions with Eve and Hb9, which are expressed in the sibling motor neurons. In chapter 3, I detail the identification of FoxD, a transcription factor that is positively regulated by the homeodomain-containing transcription factor Hb9 in the Drosophila CNS. FoxD is expressed in a subset of Hb9 positive neurons and also in all octopaminergic neurons in the Drosophila embryonic CNS. I have identified the enhancers that drive expression in these neurons and have recently generated two mutant alleles of foxD. Loss of foxD appears to result in hyperactivity, which is most pronounced in males. As octopamine is the fly equivalent of norepinephrine, these results suggest that FoxD may function in specific cells to regulate the synthesis and release of octopmaine. Thus, my thesis has identified two members of the combinatorial code of transcription factors that govern neuronal identity. In addition, it has begun to place the functions of these genes within the genetic regulatory hierarchy of this code and started to link the function of individual transcription factors to the regulation of terminal differentiation genes and animal behavior.

Book Description
The Mouse Nervous System provides a comprehensive account of the central nervous system of the mouse. The book is aimed at molecular biologists who need a book that introduces them to the anatomy of the mouse brain and spinal cord, but also takes them into the relevant details of development and organization of the area they have chosen to study. The Mouse Nervous System offers a wealth of new information for experienced anatomists who work on mice. The book serves as a valuable resource for researchers and graduate students in neuroscience. Systematic consideration of the anatomy and connections of all regions of the brain and spinal cord by the authors of the most cited rodent brain atlases A major section (12 chapters) on functional systems related to motor control, sensation, and behavioral and emotional states A detailed analysis of gene expression during development of the forebrain by Luis Puelles, the leading researcher in this area Full coverage of the role of gene expression during development and the new field of genetic neuroanatomy using site-specific recombinases Examples of the use of mouse models in the study of neurological illness

Book Description
The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types-some of which retain stem cell characteristics presumably to replenish these derivatives-requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.

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.
