The Role of Sphingolipids in Major Depressive Disorder and Associated Cognitive Impairment: Interactions with Monoaminergic Signaling, Neuroinflammation, and Neurogenesis
Major depressive disorder (MDD) affects roughly 280 million people worldwide and remains poorly treated, with one‑third of patients resistant to current drugs. Over the past two decades, lipidomics has revealed that sphingolipid metabolism—particularly the acid sphingomyelinase (ASM)/ceramide pathway—plays a central role in MDD pathophysiology. Preclinical studies show that inhibiting ASM or modulating the ceramide‑sphingosine‑1‑phosphate rheostat restores hippocampal neurogenesis and produces rapid antidepressant‑like effects, while clinical lipidomics consistently report elevated peripheral ceramides in patients. These findings suggest sphingolipids as both mechanistic targets and potential biomarkers for personalized depression therapy.
Sustaining Microglial Reparative Function Enhances Stroke Recovery
