Can pathological vs physiological C1q tagging be distinguished at the molecular level?

PARTIALLY ADDRESSED

The debate revealed a fundamental gap: whether disease-specific C1q conformational changes or co-localization patterns exist that could enable selective therapeutic targeting. This selectivity problem was identified as 'unsolvable with current technology' but remains critical for complement-based therapies.
