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. In this discussion, experts from disciplines ranging from molecular genetics to the clinic provide review and novel data concerning the aetiology of AD and the establishment of drugfinding screening methods. Neurotoxin-based approaches include exposure of rodents or non-human primates to 6-OHDA, MPTP, and agrochemicals such as the pesticide rotenone, the herbicide … In individuals with this condition, the cerebral cortex is thinner than normal and senile plaques, along with neurofibrillary tangles (NFTs), are found in the brain [2]. In recent years, the rat has been making a comeback as an Alzheimer’s disease model and the appearance of increasing numbers of transgenic rats will be a welcome and valuable complement to the existing mouse models.

Introducing a new drug to market is a complex and time-consuming process that can cost pharmaceutical companies an average $2.6 billion and ten years of research and development. Abstract. At the forefront of the quest to decipher Alzheimer’s disease are animal models. Recent studies have renewed the debate on infectious etiology in late-onset Alzheimer's disease. Alzheimer's disease (AD), also referred to simply as Alzheimer's, is a neurodegenerative disease that usually starts slowly and progressively worsens. And, when including caregivers, less than half---45 %- of those diagnosed with Alzheimer’s disease or their caregivers are aware of the diagnosis. At present, no effective cure or prophylaxis exists for Alzheimer's disease. Use a simple animal model, C. elegans (non-TG or expressing A ) to screen 500 genes identified in Aim 1, to determine whether they modify susceptibility to A , oxidative stress or aging.

Description. Alzheimer’s disease is a degenerative condition marked by a progressive decline in cognitive functioning. Recently, a nontransgenic animal model for Alzheimer’s disease dementia was developed that relies on prolonged insulin resistance in the brain . Alzheimer’s disease (AD) is most common cause of dementia. Surprisingly, this effect has never been studied to any degree in the nervous system to determine if neurons can be similarly protected from neurodegeneration, as in Alzheimer's disease. Animal models contribute to increase the knowledge on the pathophysiology of neurodegenerative diseases. Glutamine is a simple amino acid that has been clinically proven to provide tissue protection under the stress of chemo or radiation therapy as well as after intestinal surgery.
