The single GLP‐1 receptor agonist liraglutide reduced tau phosphorylation and tangle formation in the transgenic tauP301L transgenic mouse model of tauopathy, demonstrating that GLP‐1 mimetics are not only able to reduce amyloid levels, but also improve the hyperphosphorylation of tau (Hansen et al., 2016). Here, GLP1R is linked to tauopathy.
