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.

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). Missorting of tau in transgenic Both Alzheimer's disease (AD) and frontotemporal dementia (FTD) are Generation of transgenic mouse models expressing human tau in the brain has 13 Mar 2020 Immunization of transgenic.

The 2N4R isoform is the most favorable substrate for hyperphosphorylation by rodent kinases, however, these mice did not develop true NFT’s. Besides, endogenous n-3 PUFAs were observed to extend of the overall survival of tau mouse models. CONCLUSION: Endogenous n-3 PUFAs delayed the onset of Alzheimer's disease caused by tau protein dysfunction, alleviating related symptoms and significantly prolonging survival in vivo. Since the mouse models used in this study are uniquely engineered so that tau expression can be blocked by administration of the antibiotic drug doxycycline, the researchers measured neural activity in the tau-overexpressing mice and in the animals that overexpressed A-beta and tau both before and six weeks after doxycycline administration. An experimental vaccine targeting the toxic form of tau protein reduced cellular tangles in the brain — a hallmark of Alzheimer’s — and eased behavioral and motor defects in a mouse model of the disease, a study showed.

Although tau has clearly been a target of interest in these diseases, there have been relatively few good leads for small molecule therapeutics to reduce tau pathology and slow disease progression. Alzheimer's disease (AD) is the most common cause of senile dementia, for which there is presently no disease-based treatment.

In this context, it would be highly informative to study AHN in the post-mortem human brains of primary tauopathies devoid of amyloid pathology (e.g., FTLD with tau pathology, etc.). Targeting Tau Oligomers in Mouse Models of Alzheimer's Disease In a 2012 study , researchers reported four-fold higher tau oligomers in human AD brain samples vs. controls. This was an important initial finding, the first to link AD in human subjects to oligomeric tau accumulation.

The first transgenic mouse model of a tauopathy (Alz17) manifested hyperphosphorylation through altering the largest tau isoform (2N4R; 441 amino acids). The 2N4R isoform is the most favorable substrate for hyperphosphorylation by rodent kinases, however, these mice did not develop true NFT’s.
