Key findings
1. The chromatin MOF-NSL complex maintains transcription of neural metabolic networks in the developing brain.
2. Neural-specific depletion of MOF-NSL complex members results in an aberrant metabolic profile.
3. Abnormal accumulation of free fatty acids in neural cells can be directly detected by neighboring vascular pericytes.
4. Free fatty acids trigger a TLR4-NFkB driven inflammatory response in vascular pericytes leading to breakdown of neural vasculature.
5. Metabolites can mediate inter-cellular communication in the brain.
