We have further characterized this response in SOD1(G93A) mice and also revealed elevated levels of β-amyloid (Aβ) peptides in the SOD1(G93A) spinal cord, which were predominantly localized within motor neurons and their surrounding glial cells.
It was also revealed that by reducing the disulfide bond and causing a decrease in the structural stability, the amyloid fibril formation of a familial mutant SOD1 G93A was accelerated even under physiological conditions.
