## Mechanistic Overview
Fractalkine Axis Amplification via CX3CR1 Positive Allosteric Modulators starts from the claim that modulating CX3CR1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The fractalkine/CX3CR1 signaling axis represents a critical communication pathway between neurons and microglia that maintains homeostatic brain function through precise regulation of microglial act
This hypothesis proposes that targeted modulation of microglial synaptic pruning activity can restore optimal functional connectivity patterns in diseased neural networks. Microglia express complement receptor 3 (CR3) and fractalkine receptor (CX3CR1) which mediate activity-dependent synaptic elimination through complement tagging of synapses marked by C1q and C3. In pathological conditions, aberrant microglial activation leads to excessive or insufficient synaptic pruning, disrupting functional
