Comment
In both control and mutant SOD1 motoneurons, exogenous NO (addition of Detanonoate) leads to up-regulation of FasL. As a reporter of Fas activation, phophorylation of p38 kinase was quantified. However, only in the presence of G93A or G85R mutant forms of SOD1 does this mechanism lead to a Fas-dependent increase in phosphorylation of p38 kinase.
