Sentences with phrase «amounts of amyloid protein»

They injected tiny amounts of amyloid protein into the brains of the monkeys and found that old Rhesus monkeys developed Alzheimer's - like symptoms but young monkeys stayed healthy.

Not exact matches

Because PIB selectively binds to brain amyloid deposits but quickly clears from normal tissue, the chemical dye accurately indicates the amount of protein that is deposited in the living brain.

While these compounds did not reduce the amount of protein aggregates, they were found to reduce the protein's toxicity and to increase the stability of amyloid fibrils — a finding that lends further evidence to the theory that smaller assemblies of amyloid - beta known as oligomers, and not the fibrils themselves, are the toxic agents responsible for Alzheimer's symptoms.

If even trace amounts of pathogenic protein are present, they rapidly use the normal proteins to create millions of insoluble, fibrous amyloid strands.

Previous efforts at early detection have focused on beta amyloid, a protein found in abnormally high amounts in the brains of people with Alzheimer's disease.

The drug also appeared to reduce the amount of the protein amyloid beta (which forms toxic plaques in the brains of Alzheimer's patients) by decreasing the levels of metals such as zinc and copper.

The amount of beta - amyloid proteins, which make up the characteristic Alzheimer's plaques, was also much lower in the brains of the mice on the low - calorie diet.

Some studies suggest that Alzheimer's patients have an abnormally high amount of aluminum in the amyloid protein plaques that characterize the disease, although the exact connection remains unclear.

In this condition, abnormal amounts of a fibrous protein substance (amyloid) collect — for unknown reasons — in otherwise healthy kidney tissue.
