Increased GSK‐3β also occurs in other neurodegenerative conditions, like tauopathies, in which GSK‐3β is one of the kinases responsible for pathological phosphorylation of Tau (Llorens‐Martin et al, 2014); Parkinson's disease (Duka et al, 2009; Credle et al, 2015) or multiple sclerosis (Beurel et al, 2013). This evidence concerns the gene GSK3B and Parkinson disease.
