CCL2-CCR2 myeloid signaling as a selective driver of fast-fatigable motor-neuron denervation should produce a measurable proximal phenotype before late disease pathology. The decisive test is myeloid-specific CCR2 blockade with fast/slow motor-unit stratification and NMJ integrity measurements.
CCR2+ monocyte-derived macrophages, recruited to the neuromuscular junction by motor neuron-secreted CCL2, selectively infiltrate and strip fast-fatigable (IIb/IIx fibre) NMJs via matrix metalloproteinase-9 (MMP-9) cleavage of the laminin alpha-5/beta-2 NMJ scaffold. Fast motor neurons express higher CCL2 and lower TIMP-1 (MMP-9 inhibitor) than slow motor units, creating a chemokine gradient that explains selective NMJ vulnerability. Genetic or pharmacological MMP-9 blockade should preferentiall
