Intra-axonal corpora amylacea in the CNS. 1977

K Takahashi, and K Iwata, and H Nakamura

The distribution of intra-axonal corpora amylacea (IACA) in the CNS was studied in 2 cases of ALS, a hepatic encephalopathy and a Shy-Drager syndrome. A total of 149 IACAs were found. IACAs were observed far most frequently in the gracile nuclei, followed by the anterior horns of the spinal cord and in descending order; lateral geniculate bodies, reticular formation, sensory and motor nuclei in the brain stem, cerebellum and cerebral cortex. The basal ganglia, including the thalamus, contained only a few. IACA were not observed in the pyramidal tracts or in the spinal roots. About 3% of the IACA were sectioned longitudinally, together with the original small nerve fibres and abrupt enlargement of the axons due to the deposits was well demonstrated.

UI MeSH Term Description Entries
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.

D000682 Amyloid A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.

D001369 Axons Nerve fibers that are capable of rapidly conducting impulses away from the neuron cell body. Axon
