Lever 1 — reduce the inward current

Lever 1 — reduce the inward current. Lever 1 lowers the inward depolarising current (Na⁺, Ca²⁺, or proton/ATP-gated) so the pain fibre needs a stronger stimulus to fire. The promoter reads place each gene on the firing-threshold scale; the direction of intervention is anchored to cited agents such as the FDA-approved Na_V1.8 blocker. Reads are reproducible [V]; clinical

This lever groups the targets whose promoter reads place them in the lever 1 — reduce the inward current. Each target keeps its own page with its read, grades, citation, and firewall; the lever direction is cited Layer-2 biology, the reads are [V], and all clinical magnitudes are [O].

What this lever does

Lever 1 lowers the inward depolarising current (Na⁺, Ca²⁺, or proton/ATP-gated) so the pain fibre needs a stronger stimulus to fire. The promoter reads place each gene on the firing-threshold scale; the direction of intervention is anchored to cited agents such as the FDA-approved Na_V1.8 blocker. Reads are reproducible [V]; clinical magnitudes are open [O].
