What determines the selectivity of complement-mediated synaptic elimination in prolonged anesthesia?

The study shows C1qa tags synapses for microglial elimination, but doesn't explain why specific synapses are targeted while others are spared. Understanding this selectivity is crucial for preventing cognitive dysfunction while preserving necessary synaptic pruning. Gap type: unexplained_observation Source paper: Prolonged anesthesia induces neuroinflammation and complement-mediated microglial synaptic elimination involved in neurocognitive dysfunction and anxiety-like behaviors.
