This book was released on 2013-03-27 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: The misfolding and aggregation of specific proteins is an early and obligatory event in many of the age-related neurodegenerative diseases of humans. The initial cause of this pathogenic cascade and the means whereby disease spreads through the nervous system, remain uncertain. A recent surge of research, first instigated by pathologic similarities between prion disease and Alzheimer’s disease, increasingly implicates the conversion of disease-specific proteins into an aggregate-prone b-sheet-rich state as the prime mover of the neurodegenerative process. This prion-like corruptive protein templating or seeding now characterizes such clinically and etiologically diverse neurological disorders as Alzheimer ́s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, and frontotemporal lobar degeneration. Understanding the misfolding, aggregation, trafficking and pathogenicity of the affected proteins could therefore reveal universal pathomechanistic principles for some of the most devastating and intractable human brain disorders. It is time to accept that the prion concept is no longer confined to prionoses but is a promising concept for the understanding and treatment of a remarkable variety of diseases that afflict primarily our aging society.
Download or read book Tau oligomers written by Jesus Avila and published by Frontiers E-books. This book was released on 2014-08-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurofibrillary tangles (NFTs) composed of intracellular aggregates of tau protein are a key neuropathological feature of Alzheimer’s Disease (AD) and other neurodegenerative diseases, collectively termed tauopathies. The abundance of NFTs has been reported to correlate positively with the severity of cognitive impairment in AD. However, accumulating evidences derived from studies of experimental models have identified that NFTs themselves may not be neurotoxic. Now, many of tau researchers are seeking a “toxic” form of tau protein. Moreover, it was suggested that a “toxic” tau was capable to seed aggregation of native tau protein and to propagate in a prion-like manner. However, the exact neurotoxic tau species remain unclear. Because mature tangles seem to be non-toxic component, “tau oligomers” as the candidate of “toxic” tau have been investigated for more than one decade. In this topic, we will discuss our consensus of “tau oligomers” because the term of “tau oligomers” [e.g. dimer (disulfide bond-dependent or independent), multimer (more than dimer), granular (definition by EM or AFM) and maybe small filamentous aggregates] has been used by each researchers definition. From a biochemical point of view, tau protein has several unique characteristics such as natively unfolded conformation, thermo-stability, acid-stability, and capability of post-translational modifications. Although tau protein research has been continued for a long time, we are still missing the mechanisms of NFT formation. It is unclear how the conversion is occurred from natively unfolded protein to abnormally mis-folded protein. It remains unknown how tau protein can be formed filaments [e.g. paired helical filament (PHF), straight filament and twisted filament] in cells albeit in vitro studies confirmed tau self-assembly by several inducing factors. Researchers are still debating whether tau oligomerization is primary event rather than tau phosphorylation in the tau pathogenesis. Inhibition of either tau phosphorylation or aggregation has been investigated for the prevention of tauopathies, however, it will make an irrelevant result if we don’t know an exact target of neurotoxicity. It is a time to have a consensus of definition, terminology and methodology for the identification of “tau oligomers”.

Download or read book Madness and Memory written by Stanley B. Prusiner and published by Yale University Press. This book was released on 2014-04-28 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this “utterly fascinating” science memoir, the Nobel Prize–winning author chronicles his revolutionary discovery of a major cause of brain diseases (The New York Times). In 1997, Stanley B. Prusiner received the Nobel Prize in Physiology or Medicine for his research on devastating brain diseases. That he was the award’s sole recipient was entirely appropriate. His struggle to identify the agent responsible for scrapie and mad cow disease in animals, and Creutzfeldt-Jakob disease in humans, had been waged largely alone, and in some cases, in the face of strenuous opposition. In Madness and Memory, Prusiner recounts the journey to his remarkable discovery of prions—infectious proteins that replicate and cause disease, but surprisingly contain no genetic material. Along the way, he sheds light on the world of contemporary science and the meticulousness and perseverance it requires. Through his telling, the agony and triumph of years of research comes to life, along with fascinating portraits of fellow scientists racing to make breakthrough discoveries. Prusiner’s hypothesis, once considered heresy, now stands as accepted science and provides a path toward conquering such pervasive scourges as Alzheimer’s, Parkinson’s, Lou Gehrig’s, and others diseases. “Madness and Memory is the story of one of the most important discoveries in recent medical history, and it is also a vivid and compelling portrait of a life in science.” —Oliver Sacks, MD, neurologist and author of Hallucinations

Download or read book Tau Biology written by Akihiko Takashima and published by Springer Nature. This book was released on 2020-02-24 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents essential studies and cutting-edge research results on tau, which is attracting increasing interest as a target for the treatment of Alzheimer's disease. Tau is well known as a microtubule-associated protein that is predominantly localized in the axons of neurons. In various forms of brain disease, neuronal loss occurs, with deposition of hyperphosphorylated tau in the remaining neurons. Important questions remain regarding the way in which tau forms hyperphosphorylated and fibrillar deposits in neurons, and whether tau aggregation represents the toxic pathway leading to neuronal death. With the help of new technologies, researchers are now solving these long-standing questions. In this book, readers will find the latest expert knowledge on all aspects of tau biology, including the structure and role of the tau molecule, tau localization and function, the pathology, drivers, and markers of tauopathies, tau aggregation, and treatments targeting tau. Tau Biology will be an invaluable source of information and fresh ideas for those involved in the development of more effective therapies and for all who seek a better understanding of the biology of the aging brain.
