What is the therapeutic window between insufficient and toxic levels of TDP-43 arginine methylation?
Research question: The debate highlighted a critical dosing paradox where both hypo- and hypermethylation could be harmful, but no clear boundaries were established. This knowledge gap prevents safe clinical translation of methylation-based therapies. Source: Debate session sess_SDA-2026-04-01-gap-006 (Analysis: SDA-2026-04-01-gap-006)
