Tau and tauopathies
Arendt T, Stieler JT, Holzer M.. Brain research bulletin, 2016-09-09
Topic: Disease mechanisms in lab and animal studies
Most neurodegenerative diseases are characterized by intracellular aggregates of insoluble proteins. As for the majority of these disorders, aetiology and pathogenesis are only poorly understood; current nosological concepts are largely based on these molecular signatures of protein aggregates which also provide valuable tools for neuropathological differential diagnosis. The microtubule associated protein tau is one of these proteins that form intracellular fibrillary deposits in neurons and glial cells of a large variety of disorders today collectively referred to as tauopathies. While dysfunction of tau has unequivocally been shown to be able to cause neurodegeneration, the precise mechanisms of how tau is involved in neurodegenerative disorders is still poorly understood. After research has focused for several decades on the axonal function of tau and on the fibrillar tau aggregation, more recent cell biological studies have opened up new insights into the role of tau at the synapse and in the nucleus. According to currently emerging cell biological concepts, tau might play a role in the regulation of neuronal plasticity in a wide array of neuronal networks. In addition, it might be involved in regulating genome stability. The most intriguing question relevant both to physiological and pathophysiological function of tau is the biological meaning of the large heterogeneity of isoforms of tau which apparently is a rather promiscuous molecule. The present review is divided into two parts. First, we give an overview on the molecular biology and cell biology of tau and its physiological functions. The second part deals with the pathophysiology of tau and description of tauopathies which comprise more than 20 disorders including Alzheimer's disease, progressive supranuclear palsy, cortico basal degeneration, Pick's disease and others.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
