Lithium Chloride Modulates Tau Phosphorylation, Raises Toxicity Concerns

5/7/2026

Summary

Story summary

Researchers in Finland reported that lithium chloride alters Tau phosphorylation, kinase activity and Rho GTPase signaling, inhibits GSK-3? and PKC?, and a low dose in mice lowers Tau phosphorylation at one site but raises it elsewhere.
A lithium chloride dose in mutant Tau cells removed Alzheimer-linked phosphates, exceeded the therapeutic window, risked kidney and thyroid toxicity, and prompted authors to map dose-dependent kinase and Rho GTPase effects for safer therapies.
