**Molecular Mechanism and Rationale**
The microglial metabolic trained immunity hypothesis centers on a sophisticated molecular cascade initiated by perinatal immune activation that fundamentally reprograms microglial cellular metabolism through the mechanistic target of rapamycin (mTOR) and hypoxia-inducible factor 1-alpha (HIF1α) signaling axis. Upon exposure to pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs) during critical perinatal development
## **Molecular Mechanism and Rationale**
The CX3CR1-mediated fractalkine signaling pathway represents a critical regulatory axis controlling neuron-microglia communication throughout development and aging. CX3CR1 (C-X3-C motif chemokine receptor 1) functions as the sole receptor for fractalkine (CX3CL1), a unique membrane-bound chemokine expressed constitutively on neurons. Under physiological conditions, fractalkine acts as a molecular "keep-off" signal, binding to microglial CX3CR1 to maintai
