Talk:Senile plaques

From Wikipedia, the free encyclopedia

I moved the following formation and description section to the talk page, as it's largely incoherent and I don't feel qualified to clean it properly. Some of the info could be reintegrated into the article. Robotsintrouble 01:04, 21 November 2006 (UTC)

[edit] Formation and description

They can be distinguished by their composition. The amyloid of the plaques is composed of deposits of Aß-peptides (mostly 39 to 42 amino acids in length). The amyloid of the plaques is composed of deposits of Aß-peptides (mostly 39 to 42 amino acids in length). The formation seems to be a result of composition and decomposition processes. The plaques have a porous core with a decreasingly density to the periphery. A genetic background is a false genetic code of the amyloid precursor protein in chromosome 21, or false codes of presenilin 1 and 2 in chromosomes 14 and 1. A genetic risk factor ist the epsilon-4-allel of apolipoprotein E. When the dismantling of the amyloid precursor protein is disturbed, the Aß-peptides deposit in blood vessels or as extracellular plaques. But there are more factors important for the formation, like hormonal, immunological, inflammation processes, disorders of the fat and carbohydrate metabolism.
