Is HCN1 dysfunction causal or protective in EC layer II neurodegeneration?

PARTIALLY ADDRESSED

The debate revealed conflicting evidence about whether HCN1 downregulation drives neuronal death or represents a protective response to excessive excitation. This causality question is critical for determining whether HCN1 enhancement would be therapeutic or harmful. Source: Debate session sess_SDA-2026-04-01-gap-004 (Analysis: SDA-2026-04-01-gap-004)
