In ischemia, acidosis occurs in/around injured tissue and parallels disease progression. Therefore, targeting an acid-sensitive receptor offers unique advantages in achieving the spatial and temporal specificity required for therapeutic interventions. We previously demonstrated that increased expression of GPR68 (G protein-coupled receptor 68), a proton-sensitive G protein-coupled receptor, mitigates ischemic brain injury. Here, we investigated the mechanism underlying GPR68-dependent protection.
