The subgranular zone of the dentate gyrus contains neural progenitor cells with self-renewal and multilineage potency. This review describes several transgenic mouse models of Alzheimer's disease (AD), a devastating neurodegenerative disorder that causes progressive cognitive decline and is diagnosed postmortem by the presence of extracellular amyloid-β (Aβ) plaques and intraneuronal tau neurofibrillary tangles in the cerebral cortex. DNA repair activity is deficient in AD patient brains, especially DNA polymerase β (Polβ), a key protein in DNA base excision.

We used the triple transgenic mouse model (3xTg-AD) to reproduce Aβ (amyloid plaques) and tau (neurofibrillary tangles) neuropathologies. Survival curves for 5- to 6-week-old 5XFAD and wild-type littermate (WT) mice challenged via IC injections with 105, 104, or 103 PFUs of 17syn+ strain per mouse (A); or 104, 5 103, or 103 PFUs of McKrae strain per mouse (B). Here, we demonstrate that learning and memory deficits observed in a transgenic mouse model of Alzheimer's disease can be ameliorated by enrichment. In this study, we investigated the potential beneficial effects of luteolin on memory deficits and neuroinflammation in a triple-transgenic mouse model of Alzheimer’s disease (AD) (3 × Tg-AD). Alzheimer’s disease (AD) is an age-related neurodegenerative disorder characterized by progressive memory loss [], the deposition of extracellular Aβ plaques, and intracellular neurofibrillary tangles (NFTs) composed of tau aggregates [2, 3].Tau is a microtubule (MT)-associated protein predominantly expressed in neuronal axons with a primary function of promoting assembly and … Review APP mouse models for Alzheimer’s disease preclinical studies Hiroki Sasaguri1,2,*, Per Nilsson1,3, Shoko Hashimoto1, Kenichi Nagata1, Takashi Saito1,4, Bart De Strooper5,6,7, John Hardy8, Robert Vassar9, Bengt Winblad3 & Takaomi C Saido1,** Abstract Animal models of human diseases that accurately recapitulate Naphthalene Monoimide Derivative Ameliorates Amyloid Burden and Cognitive Decline in a Transgenic Mouse Model of Alzheimer's Disease Sourav Samanta , Bioorganic Chemistry Laboratory, New Chemistry Unit, Jawaharlal Nehru Centre for Advanced … 2000).Mice were chronically exposed to a cocktail of cypro, mepa, and pyri at the regulatory limit dose of 0.1 μ g / L for each compound over 9 months through tap water.

Offering a potential early intervention for Alzheimer’s disease (AD), researchers at University of California, San Diego School of Medicine and Cenna Biosciences, Inc. have identified compounds that block the production of beta amyloid peptides in mice. The main biomarkers associated with AD are protein amyloid-β (Aβ) plaques and protein tau neurofibrillary tangles, which are responsible for brain neuroinflammation mediated by microglial cells. Even so, many models have been developed to gain insights into various aspects of AD. 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 present study explores the expression of the ECB system, the ECB-related receptor GPR55, and cognitive functions (novel object recognition; NOR) in the 5xFAD (FAD: family Alzheimer’s disease) … Peptides 23 , 2223–2226 (2002) CAS Article Google Scholar The accumulation of amyloid-ß; protein (Aß) in Alzheimer's disease (AD) is a well known pathological event.
