Abstract:
The expression of protein kinase C (PKC), a calcium- and phospholipid-dependent signaling molecule, was studied immunohistochemically in the spinal motor neurons of cases of sporadic amyotrophic lateral sclerosis (SALS). In the normal spinal cord, intense PKC immunoreactivity was found in subsets of large motor neurons. PKC immunoreactivity was markedly decreased in the spinal motor neurons of SALS. The result suggests that down-regulation of PKC is associated with the degeneration of spinal motor neurons in SALS.
