Ceramide-Sphingosine-1-Phosphate Axis Rebalancing via SPHK1 Enhancement
🧪 Overview
Selective enhancement of sphingosine kinase 1 (SPHK1) activity to shift the ceramide/S1P balance toward the pro-survival S1P pathway. This would reduce ceramide-mediated apoptosis and tau hyperphosphorylation while promoting synaptic plasticity through S1P receptor signaling.
Debate provenance: derived from debate `sess_SDA-2026-04-04-frontier-lipidomics-dcdbc360` on question: How do alterations in brain lipid metabolism—including gangliosides, phospholipids, cholesterol transport, and sphingolipids—contribute to amyloidogenesis, tau pathology, and synaptic dysfunction in Alzheimer disease? Examine: (1) APOE-lipid particle composition and functional consequences, (2) gang. Consensus signal: domain_expert, synthesizer, theorist discussed the mechanism terms Ceramide-Sphingosine-1-Phosphate, Enhancement, Rebalancing, S1P, SPHK1, phosphorylation, signaling, synaptic. Novelty signal: synthesizer-consensus.
