Aquaporin‑1 regulates microglial polarization and inflammatory response in traumatic brain injury.

ABSTRACT: The present study investigated the mechanisms by which aquaporin 1 (AQP1) influences microglial polarization and neuroinflammatory processes in traumatic brain injury (TBI). A model of TBI was generated in AQP1‑knockout mice to assess the impact of AQP1 deletion on inflammatory cytokine release, neuronal damage and cognitive function. Immunofluorescence, reverse transcription‑quantitative PCR, western blotting and enzyme‑linked immunosorbent assay were employed to evaluate pro‑inflammatory and anti‑inflammatory markers. Behavioral assessments, including the Barnes maze, were performed to determine cognitive outcomes. Moreover, AQP1 knockout inhibited the activation of inflammation‑related signaling pathways, including nuclear factor‑κB, Janus kinase/signal transducer and activator of trans
