Abstract AIM We investigated the mechanism of action whereby exposure to dimethyl phthalate (DMP), an environmental pollutant, causes cognitive impairment. METHODS Network pharmacology was used analyze targets and regulatory networks associated with DMP-brain injury-cognitive The intake DMP simulated by exposure, Morris water maze adopted examine tissue levels inflammatory cytokines were detected. Brain damage assayed H&E Nissl staining, protein expression identified Western blotting. effects observed after separate application siRNA-COX2 celecoxib-COX2 inhibitors. In in vitro experiment, on microglia activation investigated. RESULTS revealed that PTGS2 (COX2) significantly correlated DMP, which could act through COX2. After mice showed significant brain injury impairment, along upregulation cytokines. inhibit ameliorate impairment mice. results activate cause neuroinflammation. CONCLUSION can induce neuroinflammation COX2-mediated microglia, resulting COX2 is important target for action.
