LiCl-induced immunomodulatory periodontal regeneration via the activation of the Wnt/β-catenin signaling pathway.

The application of Wnt activator LiCl facilitates the recruitment of macrophages to defect sites and regulates their phenotypic switching in favor of periodontal regeneration. Suppression of Wnt/β-catenin pathway could attenuate the LiCl-induced immunomodulatory effect. Taken together, the Wnt/β-catenin pathway may be targeted for therapeutic interventions in periodontal diseases.
