How do sphingomyelin/ceramide ratios specifically regulate BACE1 clustering and activity in synaptic vs non-synaptic lipid rafts?

PARTIALLY ADDRESSED

The debate established that ceramide accumulation affects amyloid-β processing but didn't resolve the spatial specificity of this mechanism. Understanding differential raft regulation could enable targeted interventions that preserve synaptic function while reducing amyloidogenic processing.
