Book Description
The amyloid precursor protein APP plays a key role in the pathogenesis of Alzheimer’s disease (AD), as proteolytical cleavage of APP gives rise to the Aβ peptide which is deposited in the brains of Alzheimer patients. Despite this, our knowledge of the normal cell biological and physiological functions of APP and the closely related APLPs is limited. This may have hampered our understanding of AD, since evidence has accumulated that not only the production of the Aβ peptide but also the loss of APP-mediated functions may contribute to AD pathogenesis. Thus, it appears timely and highly relevant to elucidate the functions of the APP gene family from the molecular level to their role in the intact organism, i.e. in the context of nervous system development, synapse formation and adult synapse function, as well as neural homeostasis and aging. Why is our understanding of the APP functions so limited? APP and the APLPs are multifunctional proteins that undergo complex proteolytical processing. They give rise to an almost bewildering array of different fragments that may each subserve specific functions. While Aβ is aggregation prone and neurotoxic, the large secreted ectodomain APPsα - produced in the non-amyloidogenic α-secretase pathway - has been shown to be neurotrophic, neuroprotective and relevant for synaptic plasticity, learning and memory. Recently, novel APP cleavage pathways and enzymes have been discovered that have gained much attention not only with respect to AD but also regarding their role in normal brain physiology. In addition to the various cleavage products, there is also solid evidence that APP family proteins mediate important functions as transmembrane cell surface molecules, most notably in synaptic adhesion and cell surface signaling. Elucidating in more detail the molecular mechanisms underlying these divers functions thus calls for an interdisciplinary approach ranging from the structural level to the analysis in model organisms. Thus, in this research topic of Frontiers we compile reviews and original studies, covering our current knowledge of the physiological functions of this intriguing and medically important protein family.

Book Description
Providing widely used techniques in genetic model systems and many complementing animal models, Brain Development: Methods and Protocols focuses its expert contributions on two key technical aspects of developmental neurobiology: detection of gene expression and functional characterization of developmental control genes. Covering animal models such as the fruit fly, zebra fish, chicken, and mouse, this detailed book views in situ hybridization, reporter gene expression, and immunohistochemical staining methods, as well as RNA interference, Morpholino, or transgenic techniques through the prism of these models. Written in the highly successful Methods in Molecular Biology series format, chapter include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and cutting-edge, Brain Development: Methods and Protocols aims to provide precise technical protocols but also allows for comparing a wide range of protocols in different tissues and species.

Book Description
A satellite symposium entitled "Myelination and Demyelination: Recent Chemical Advances" was held in Helsinki from August 29 to 31, 1977, after the Sixth International Meeting of the International Society for Neurochemistry (ISN) in Copenhagen. Myelin is a nervous tissue structure that is most suitable as a subject of biochemical investigation. It is easy to isolate in a highly purified form, is rather stable even after death, and is af fected by a variety of neurological and other diseases. Its lesions are particularly important in the study of multiple sclerosis, a disease which is relatively prevalent in Finland and has therefore been of interest to a great many Finnish scientists. The first half of this book is concerned with the biochemical composition and molecular organization of myelin, the second half with the experimental and clinical aspects of demyelination. The comments given after each of the presentations at the symposium were not recorded as such, but each author was requested to modify his or her paper accordingly. The editing and publication of this book would not have been possible without the excellent efforts and co-operation of my wife, Mrs. L.-M. Palo, acting as general secretary and later as editorial secretary of the symposium. As Organizing Committee Chairman, I would also like to thank the members of the Committee: Dr. M. Haltia, Dr. E. Kivalo, Dr. T. Kosunen, Dr. M. Panelius, and especially Dr.
