How do different HCN isoforms (HCN1, HCN2, HCN4) contribute differentially to epilepsy pathogenesis?

OPEN

The abstract mentions that HCN1, HCN2, and HCN4 all play pathogenic roles in epilepsy but doesn't explain their distinct contributions. This mechanistic gap limits the development of isoform-specific therapeutic strategies for epilepsy treatment.
