Pathways of cysteine metabolism in MND/ALS.
Analysis of plasma from MND/ALS patients has shown no significant differences in metabolism of cysteine derivatives, although a sub-set of the population has raised glutamate values. Cysteine dioxygenase was found to have reduced activity in vitro, consistent with previous findings of a high plasma cysteine/sulphate ratio.
