2.6.1.7 kynurenine-oxoglutarate transaminase corpus amylaceum KAT I may be involved in mechanisms of retinal ageing and neurodegeneration leading to formation of corpora amylacea 673773 2.6.1.7 kynurenine-oxoglutarate transaminase corpus amylaceum KAT II may be involved in mechanisms of retinal ageing and neurodegeneration leading to formation of corpora amylacea 673773 3.4.24.87 ADAMTS13 endopeptidase corpus amylaceum in astrocytes of aging brains and patients with neurodegenerative conditions. Corporae amylaceae include glycosylated material, ubiquitin, and an assortment of proteins derived from neuronal cytoplasm. Many of these proteins are not specifically localized to neurons or astrocytes, some components of corpora amylacea, such as complement proteins, are most abundantly expressed outside the central nervous system. Corporae amylaceae can result from a conglomeration of interacting proteins from degenerating neurons and from extravasated blood elements released after transient breakdown of the blood-brain barrier 713116
