Validation experiment designed to validate causal mechanisms targeting N/A in rats. Primary outcome: rescue of cognitive dysfunction and anxiety-like behaviors
This intervention experiment involved depleting microglia in the sevoflurane-induced neurotoxicity model to test whether microglial activation was necessary for the observed pathological changes. The study aimed to determine if removing microglia could prevent or reverse the neuroinflammation, complement activation, synaptic loss, cognitive dysfunction, and anxiety-like behaviors induced by prolonged anesthesia. The results showed that microglial depletion ameliorated neuroinflammation activation, reduced complement system activation, rescued synaptic loss, and improved both cognitive dysfunction and anxiety-like behaviors. This experiment provided crucial evidence that microglia play a central role in the pathological cascade triggered by prolonged anesthesia.
