| Study Title | Untargeted lipidomics profiling of TSC microglia |
| Study Summary | In this study, human microglia from induced pluripotent stem cells (iPSCs) derived from a TSC patient cohort were generated . With a comprehensively molecular and cellular characterization on TSC microglia, including transcriptomics, proteomics/phosphopreteomics, and lipidomics, patient-carrying TSC2 mutations lead to aberrant lipid metabolism were found, in particular, upregulated glycerophosphocholines and fatty acyls in TSC microglia, resulting in increased phagocytosis and inflammation. Strikingly, the dysregulated lipid metabolism in TSC microglia is driven by hyper-activation of mTOR-LPL pathway. Furthermore, cellular and electrophysiological assessments of neuron/microglia co-cultures revealed that TSC microglia directly affect neuronal development and excitability as well as neuronal network activity, which could be largely ameliorated by mTOR/LPL inhibition |
