Background: Leptin recruits KATP channels to the pancreatic β-cell membrane. Results: Leptin causes a parallel increase in Kv2.1 channel density that is dependent on AMPK, PKA, and actin depolymerization. Conclusion: Leptin signaling leads to simultaneous increases in KATP and Kv2.1 channel densities. Significance: Concerted KATP and Kv2.1 channel trafficking regulation by leptin may result in coordinated inhibition of β-cell excitability.
