Neuronal 'traffic jam' marks early Alzheimer's disease

...derlies Alzheimer's pathology, called beta amyloid precursor protein (beta-APP), triggers defects in axonal transport. A defective version of beta-APP is cleaved to form an aberrant form of amyloid beta (A-beta) peptide that makes up the plaques that surround the neurons of people with Alzheimer's disease. "W...

Researchers extend mouse lifespan by protecting against free radicals

... a waste product of metabolism and it can be a the precursor of free radicals that can damage the cell. The damage can in turn lead to more flaws in the cell's chemical processes, making a vicious cycle that leads to more free radicals, more cellular damage, and so on. The researchers studied mice with a gene...

Pinpointing the cause of a neurodegenerative disorder

...that causes Parkinson's disease, or of the amyloid precursor protein that causes Alzheimer's disease, can cause pathology," she said. "So, this raises the question of whether mutations in the genes for these proteins enhance their normal action. "Importantly, such insights can now guide studies that focus on ...

Pinpointing a culprit molecule in Alzheimer's disease

...ically altered to overproduce mutant human amyloid precursor protein (APP). It is this protein that, when clipped by enzymes, produces the amyloid beta (Ab) peptide that clusters into the amyloid plaque that clogs the brain and kills brain cells. The clipping of APP produces two types of amyloid beta peptide-...

Bacteria are key to 'green' plastics, drugs

Engineered bug makes key chemical precursor from grain sorghum Trials have begun in Kansas on a "green" production method for succinate, a key ingredient of many plastics, drugs, solvents and food additives. Developed at Rice University, the technology uses a genetically modified form of the ...

Targeting a key enzyme with gene therapy reversed course of Alzheimer's disease in mouse models

...plaques are formed when enzymes cleave the amyloid precursor protein (APP) releasing the toxic beta amyloid fragments that clump together to form the sticky plaques. One of the enzymes doing the cleaving is called beta secretase or BACE1. And although the production of beta amyloid occurs in all brains, healt...
