"synthesis_summary": "Consensus: Cell-Autonomous vs Non-Cell-Autonomous Mechanisms of Mutant FUS Neuromuscular Denervation is a valid debate target because it is anchored to The CCL2-CCR2 axis drives neuromuscular denervation in amyotrophic lateral sclerosis and asks a falsifiable question about mutant FUS effects split between motor-neuron intrinsic stress and glial/NMJ inflammatory signaling. Dissent: the source evidence does not yet prove causality, and co-culture systems can exaggerate glial effects and underrepresent muscle and peripheral immune contributions. The next step is isogenic motor-neuron, astrocyte, and microglia chimeric co-cultures with NMJ formation and denervation readouts."
