Alzheimer's disease Aβ peptide induces an increase in Na,K-ATPase glutathionylation.

We have shown that the inhibition of Na,K-ATPase during its long-term incubation with amyloid beta (Aβ), an Alzheimer's disease protein, is caused by the change in the thiol redox status of cells leading to induction of glutathionylation α-subunit of Na,K-ATPase. To restore the activity of Na,K-ATPase, it is proposed to use reducing agents, which promote normalization of the redox status of cells and deglutathionylation of the protein.
