Does C1q function differ based on subcellular localization or binding partner identity?

PARTIALLY ADDRESSED

The debate revealed fundamental disagreement about whether C1q has spatially distinct functions at synapses versus microglia, or whether outcomes depend solely on binding partners. This mechanistic uncertainty undermines all proposed therapeutic strategies targeting C1q.
