Experimental Models of Tauopathy  - From Mechanisms to Therapies.

Experimental Models of Tauopathy - From Mechanisms to Therapies. Adv Exp Med Biol. 2019;1184:381-391 Authors: Götz JJ, Götz J Abstract Animal models have been instrumental in reproducing key aspects of human tauopathy. In pursuing these efforts, the mouse continues to have a prominent role. In this chapter, we focus on models that overexpress wild-type or mutant forms of tau, the latter being based on mutations found in familial cases of frontotemporal dementia. We review some of these models in more detail and discuss what they have revealed about the underlying pathomechanisms, as well as highlighting new developments that exploit gene editing tools such as TALEN and CRISPR. Interestingly, when investigating the role of tau in impairing cellular functions, common themes emerge. Because tau is a scaffolding protein that aggregates in the somatodendritic domain under pathological conditions, it traps proteins such as parkin and JIP1, preventing them from executing their normal function in mitophagy and axonal transport, respectively. Another aspect is the emerging role of tau in the translational machinery and the finding that the somatodendritic accumulation of tau in Alzheimer's disease may in part be due to the induction of the de novo synthesis of tau by amyloid-β via the Fyn/ERK/S6 pathway. We further discuss treatment strategies such as tau-based vaccinations and therapeutic ultrasound and conclude by discussing whether there is ...

This study delves into the mechanisms by which a short period of fasting can accelerate wound healing. Fasting triggers many of the same cellular stress responses, such as upregulated autophagy, as occur during the practice of calorie restriction. It isn't exactly the same, however, so it is always worth asking whether any specific biochemistry observed in either case does in fact occur in both situations. In particular, the period of refeeding following fasting appears to have beneficial effects that are distinct from those that occur while food is restricted. Multiple forms of therapeutic fasting have been repor...

BACKGROUND: Previous evidence suggests that slower gait speed is longitudinally associated with cognitive impairment, dementia and falls in older adults. Despite this, the longitudinal relationship between gait speed, cognition and falls in those with a di...

AbstractVascular dementia (VD) is the second most common cause of dementia following Alzheimer ’s disease (AD). The major symptoms of VD including memory loss, language deficits and impairment of executive functions. Its specific etiology and pathogenesis remain unknown. Currently, treatment options of VD are still limited. The therapeutic strategies aim to control the vascular risk factors and improve the cognitive function. In recent years, cell therapy for neurodegenerative diseases has attracted a great deal of attention. Evidence suggested that stem cell transplantation could improve the symptoms of cerebral inf...

We report the case of a 32 years old man with a family history of  early onset AD associated with a PSEN1 mutation in the exon 4 (I83T). The proband's, carrying the mutation,  present a refractory epilepsy predating cognitive decline. We discuss the physiopathological mechanisms of epilepsy during AD associated with PSEN 1 mutation, the possibility of linking this epilepsy to the mutation?.

AbstractIt has been accepted that kidney function is connected with brain activity. In clinical studies, chronic kidney disease (CKD) patients have been found to be prone to suffering cognitive decline and Alzheimer ’s disease (AD). The cognitive function of CKD patients may improve after kidney transplantation. All these indicators show a possible link between kidney function and dementia. However, little is known about the mechanism behind the relation of CKD and AD. This review discusses the associations b etween CKD and AD from the perspective of the pathophysiology of the kidney and complications and/or concomit...

CONCLUSIONS: Our study results corroborate earlier findings that the CSF tool is of added value to the diagnostic workup in daily clinical practice outside tertiary referral centers. CSF levels can best be used in patients under 66 years of age. Given the limited use of this tool in settings outside research facilities, we recommend that the usefulness of CSF biomarkers is studied in a multicenter study. When in the future CSF levels can be reliably measured in plasma, this may become even more relevant. PMID: 32224618 [PubMed - as supplied by publisher]

Authors: Khosravi S, Harner ME Abstract Mitochondria perform a plethora of functions in various cells of different tissues. Their architecture differs remarkably, for instance in neurons versus steroidogenic cells. Furthermore, aberrant mitochondrial architecture results in mitochondrial dysfunction. This indicates strongly that mitochondrial architecture and function are intimately linked. Therefore, a deep knowledge about the determinants of mitochondrial architecture and their function on a molecular level is of utmost importance. In the past decades, various proteins and protein complexes essential for formatio...
