A molecular basis for selective therapeutic intervention in Alzheimer's diseaseOctober 07, 2005Alzheimer's disease, a complex neurological disorder, has as one of its hallmarks the presence of senile plaques in the brains of affected individuals. These senile plaques are rich in a toxic amyloid peptide termed Aâ. The mechanisms underlying the production of Aâ are complex, but it is known that this peptide is derived from a larger precursor known as the amyloid precursor protein (AâPP). Interestingly, and of potential therapeutic significance, AâPP can be processed within the cell via different pathways, some of which preclude the formation of the toxic peptide Aâ. Cellular stress has been associated with the disease and may impact upon AâPP processing and, consequently, toxic amyloid peptide termed Aâ production. University of Aveiro researchers, in their recent article 'Cellular stress affects phosphorylation dependent AâPP processing' by A. G. Henriques et al, published in the Journal of Alzheimer's Disease, Vol. 7, pp 201-212, addressed how the non-toxic amyloid precursor protein (AâPP) processing was affected by cellular stress. The research was carried out in the recently established Neuroscience Laboratory of the University of Aveiro, headed by Prof. Odete A. B. da Cruz e Silva. The University of Aveiro was created in 1973 and is generally recognized as one of the most dynamic universities in Portugal, being a member of the European Consortium of Innovative Universities. The university prides itself in the quality of its research groups and, in addition to its traditional strength in areas such as Material Science, Signal Transduction, Environment and Marine Studies, Electronics and Telematics, Telecommunications and Telemedicine, it has recently promoted the development of internationally competitive research in Biomolecular and Health Sciences.

Study offers window into human behavior, brain disease UCSF scientists have identified a cell population that is a primary target of the degenerative brain disease known as frontotemporal dementia, which is as common as Alzheimer's disease in patients who develop dementia before age 65. New imaging compound might 'see' Alzheimer's earlier A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine. Testosterone therapy may prevent Alzheimer's disease Researchers at the University of Southern California have discovered a direct link between loss of testosterone and the development of an Alzheimer's-like disease in mice. They also discovered that testosterone treatment slows progression of the disease. Androgen therapy may slow progress of Alzheimer's disease Experiments on mouse models of Alzheimer's disease (AD) suggest that treatment with male sex hormones might slow its progression. Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease Scientists collaborating at Cornell University in Ithaca and Weill Cornell Medical College in New York City have identified a panel of 23 protein biomarkers in cerebrospinal fluid that acts as a neurochemical "fingerprint," which doctors might use someday to identify patients living with Alzheimer's disease. Study shows cats can succumb to feline Alzheimer's disease Ageing cats can develop a feline form of Alzheimer's disease, a new study reveals. Scientists at the Universities of Edinburgh, St Andrews, Bristol and California have identified a key protein which can build up in the nerve cells of a cat's brain and cause mental deterioration. Scientists develop a new way to target Alzheimer's disease The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by interfering with the deadly embrace of these proteins. Complaints About Memory Are Associated With Alzheimer-Related Brain Damage Researchers at Rush University Medical Center found that having complaints about memory problems is associated with changes in the brain related to Alzheimer's disease. They reported their findings in the November 2006 issue of Neurology. More insight into Alzheimer's disease with Stanford discovery of possible cause A peacekeeper in the body's defenses against infection may hold the key to understanding-and eventually treating-Alzheimer's disease. Researchers at the Stanford University School of Medicine discovered that when a molecule responsible for dialing down the immune system malfunctions in the brain cells of mice, the rodents develop symptoms of the degenerative brain disease.
