Development Of Dopaminergic Neurons

Theneurotransmitter dopamine has just celebrated its 50thbirthday. The discovery of dopamine as a neuronal entity in the late 1950s and the notion that it serves in neurotransmission has been a milestone in the field of neuroscience research. This milestone marked the beginning of an era that explored the brain as an integrated collection of neuronal systems that one could distinguish on basis of neurotransm- ter identities, and importantly, in which one started to be able to pinpoint the seat of brain disease. The mesodiencephalic dopaminergic (mdDA) system, previously designated as midbraindopaminergic system, has received much attention since its discovery. The initial identification of dopamine as a neurotransmitter in the central nervous system (CNS) and its relevance to psychiatric and neurological disorders have stimulated a plethora of neurochemical, pharmacological and genetic studies into the function of dopamine neurons and theirprojections. In the last decade, studies on gene expression and development have further increased the knowledge of this neuronal population and have unmasked a new level of complexity. The start of the molecular dissection of the mdDA system has been marked by the cloning and characterization ofNurrl and Pitx3. These transcription factors were shown to have a critical function during mdDA development. These initial studies have been followed by the identification of many other proteins, which have a crucial function in the creation of a dopamine neuron permissive region, induction of precursors, induction of terminaldifferent- tion and finally maintenance of the mdDA neuronal pool.

This volume provides a variety of technical approaches to study dopamine system function and dysfunction. Chapters guide readers through dopamine release in ex vivo and freely moving animals, multi-recording devices for in vivo simultaneous single cell and population activity, in silico modeling of dopamine neurons activity, neuroanatomical approaches, unbiased stereology, ultrastructural analyses of dopaminergic neurons, and axonal innervation. Additionally, chapters also incorporate pharmacological tools to model neuropsychiatric diseases, novel behavioral paradigms to dissect dopamine's role in behavior, and functional imaging to follow human dopamine system development. In the Neuromethods series style, chapters include the kind of detail and key advice from the specialists needed to get successful results in your laboratory. Comprehensive and cutting-edge, Dopamine Neurotransmission aims to be a valuable resource for researchers in various disciplines.

This book provides a unique and timely multidisciplinary synthesis of our current knowledge of the anatomy, pharmacology, physiology and pathology of the substantia nigra pars compacta (SNc) dopaminergic neurons. The single chapters, written by top scientists in their fields, explore the life cycle of dopaminergic neurons from their birth to death, the cause of Parkinson's disease, the second most common and disabling condition in the elderly population. Nevertheless, the intracellular cascade of events leading to dopamine cell death is still unknown and, consequently, treatment is symptomatic rather than preventive. The mechanisms by which alterations cause neuronal death, new therapeutic approaches and the latest evidence of a possible de novo neurogenesis in the SNc are reviewed and singled out in different chapters. This book bridges basic science and clinical practice and will prepare the reader for the next few years, which will surely be eventful in terms of the progress of dopamine research.

Trophic Regulation of the Basal Ganglia: Focus on Dopamine Neurons examines neurotransmitters. The book first discusses the role of fibroblast growth factor-2 (FGF-2) and ganglioside GM1 and the trophic regulation of the basal ganglia. Biochemical and histochemical studies on the cellular localization of FGF-2; mapping of FGF-2 and its receptors in the basal ganglia postnatally and adulthood; and mapping of the ganglioside GM1 distribution in the basal ganglia are presented. The text also explains glucocorticoid and estrogen effects on the nigrostriatal and mesolimbic dopaminergic systems; factors associated to dopaminergic cell death in Parkinson's disease; and compensatory mechanisms at dopamine D-2 receptors. The book also describes the effects of brain-derived neurotrophic factor on injured dopaminergic neurons; role of gangliosides and trophic factors in brain repair; and features of the trophic action of polyamines. The text also underscores the presence of interleukin-1 in the central nervous system; neuropeptides synthesis in astrocytes; and astrocytic kynurenines as modulators of dopaminergic function in the rat basal ganglia. The selection is a good source of information for readers wanting to study neurotransmitters.

This comprehensive reference provides a detailed overview of current concepts regarding the cause of Parkinson's disease-emphasizing the issues involved in the design, implementation, and analysis of epidemiological studies of parkinsonism.

The discovery of dopamine in 1957-1958 was one of the seminal events in the development of modern neuroscience, and has been extremely important for the development of modern therapies of neurological and psychiatric disorders. Dopamine has a fundamental role in almost all aspects of behavior: from motor control to mood regulation, cognition and addiction and reward, and dopamine research has been unique within the neurosciences in the way it has bridged basic science and clinical practice. Over the decades research into the role of dopamine in health and disease has been in the forefront of modern neuroscience. The Dopamine Handbook is the first single-volume publication to capture current progress and excitement in this dynamic research field.
