The recent identification of age-related accumulation of advanced glycation end-products (AGE) of the Maillard reaction in neurons and vessels of the human brain suggests the involvement of AGE in the aging process. A variety of inclusions such as lipofuscin granules, corpora amylacea, Hirano bodies, granulovacuolar degenerations and ubiquitin-positive granular structures are found in the aged human brain. These age-related inclusions contain insoluble and non-degradable proteins. Advanced glycation end-product-modified proteins are also known to be insoluble and protease resistant. The similarity between proteins in such inclusions and AGE-modified proteins suggests the presence of AGE in inclusions. To investigate this possibility, the presence of two known AGE structures, N epsilon(carboxymethyl)lysine (CML) and pentosidine, was examined in age-related inclusions. Immunohistochemical examination of the medial temporal area of brain tissues obtained at autopsy from seven non-demented elderly individuals demonstrated positive reactions in lipofuscin granules and corpora amylacea but not in other inclusions for anti-CML and anti-pentosidine antibodies. As CML and pentosidine are glycoxidation products among AGE, the results suggest that glycation and/or oxidation may be involved in the formation of lipofuscin granules and corpora amylacea.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D002479 Inclusion Bodies A generic term for any circumscribed mass of foreign (e.g., lead or viruses) or metabolically inactive materials (e.g., ceroid or MALLORY BODIES), within the cytoplasm or nucleus of a cell. Inclusion bodies are in cells infected with certain filtrable viruses, observed especially in nerve, epithelial, or endothelial cells.
