Human and Microbial Proteins From Corpora Amylacea of Alzheimer's Disease.


ABSTRACT: Corpora amylacea (CA) are spherical bodies mainly composed of polyglucans and, to a lesser extent, proteins. They are abundant in brains from patients with neurodegenerative diseases, particularly Alzheimer's disease. Although CA were discovered many years ago, their precise origin and function remain obscure. CA from the insular cortex of two Alzheimer's patients were purified and the protein composition was assessed by proteomic analysis. A number of microbial proteins were identified and fungal DNA was detected by nested PCR.A wide variety of human proteins form part of CA. In addition, we unequivocally demonstrated several fungal and bacterial proteins in purified CA. In addition to a variety of human proteins, CA also contain fungal and bacterial polypeptides.In conclusion, this paper suggests that the function of CA is to scavenge cellular debris provoked by microbial infections.
