CSF biomarkers and incipient Alzheimer disease in patients with mild cognitive receptor-mediated excitotoxicity in a mouse model of Huntington's disease Cerebrospinal fluid levels ofβ-amyloid 1-42, but not of tau, are fully changed 

Alzheimers, galna kor och Skellefteåsjukan. Vi forskar på kopplingen mellan felveckning av proteiner och sjukdomar så som amyloidos och prionsjukdom.

Aim and methods We used the triple transgenic mouse model (3xTg-AD) to reproduce Aβ (amyloid plaques) and tau (neurofibrillary tangles) neuropathologies. We analyzed Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) and tau deposition in brain. It has emerged that Aβ toxicity is tau dependent, although mechanistically this link remains unclear. Here, we show that tau, known as axonal protein, has a dendritic function in postsynaptic targeting of the Src kinase Fyn, a substrate of which is the NMDA receptor (NR).

Two recent NIA-supported studies led by Dr. Virginia M-Y Lee, at the University of Pennsylvania School of Medicine, have taken important steps forward in that quest by creating a new mouse model for Alzheimer's disease that more realistically mimics the different forms of tau — and the key interactions between amyloid-beta and tau — seen in the human version of the disease. Synthetic tau fibrils mediate transmission of neurofibrillary tangles in a transgenic mouse model of Alzheimer's-like tauopathy J Neurosci . 2013 Jan 16;33(3):1024-37. doi: 10.1523/JNEUROSCI.2642-12.2013. Summary This mouse was designed to express only human tau isoforms (Andorfer et al., 2003). It was made by mating two existing lines of tau mice, 8c (Duff et al., 2000) and tau knock-out mice (Tucker et al., 2001).

This study investigates for the first time the role of tau for Alzheimer’s disease with combined structural and functional connectivity on a mouse model of tauopathy. We report here the unexpected result that the functional brain networks respond to the expression of extra TauRD, independent of its aggregation and cognitive decline.

Mouse models, tau tangles and neurodegeneration in Alzheimer’s disease. Neurodegenerative diseases – Alzheimer’s disease, Parkinson’s disease, motor neuron diseases, to name the commonest – are illnesses that, though their behavioural symptoms may vary, are all characterised by the progressive impairment and death of neurons.

The cholinergic Alzheimer’s disease-like dysfunction has been characterized for several Tg rodent tau models, most recently in the THY-Tau22 mouse, a model that displayed major hippocampal Alzheimer’s disease-like tau pathology within the septo-hippocampal pathway (Belarbi et al., 2009).

It was made by mating two existing lines of tau mice, 8c (Duff et al., 2000) and tau knock-out mice (Tucker et al., 2001). The vaccine was tested in a mouse model of Alzheimer’s, which was characterized by the development of tau tangles, as well as movement, memory, and behavior problems after the age of six months. Animals received intramuscular injections of AV-1980R plus an adjuvant (AV-1980R/A) — a secondary substance that boosts immune response — on four Duff, Davies and colleagues created a humanized tau (htau) model by expressing wild-type human MAPT genomic DNA on a mouse Mapt knockout background [ 37 ]. A vaccine produced using virus-like particles was able to improve cognitive functioning and reduce the accumulation of tau protein aggregates — a hallmark of Alzheimer’s disease — in a mouse model of the disease, a study shows.
