Key Takeaway
Note that this narrative review lacks reported outcomes and safety data for voltage-dependent K+ channels.

This narrative review synthesizes existing literature on voltage-dependent K+ channels across rodent and human studies. The scope of the review encompasses various investigations into these channels, though specific study populations and interventions are not detailed in the source text. The authors do not report sample sizes, primary outcomes, or secondary outcomes for the individual studies included in their synthesis.

The review does not provide pooled effect sizes or specific numerical data regarding efficacy or safety. Adverse events, tolerability, and discontinuations are not reported in the source material. Consequently, the authors do not make definitive claims about clinical benefits or risks based on the available evidence.

Limitations acknowledged by the authors include the absence of reported outcomes and safety data for the reviewed studies. The review does not specify a particular setting or follow-up duration. Due to these gaps, the practice relevance is not explicitly defined, and clinicians should interpret the findings with caution.

Insulin secretion from pancreatic islet β-cells is governed by both metabolic and electrogenic pathways. The latter involves changes in membrane potential regulated by various potassium channels, including ATP-sensitive K+ (KATP) channels, Ca2+-sensitive K+ (KCa) channels, and voltage-dependent K+ (Kv) channels. Glucose metabolism elevates the ATP/ADP ratio, leading to the closure of KATP channels and subsequent membrane depolarization. Such depolarization opens voltage-dependent Ca2+ channels (vDCCs), allowing Ca2+ influx that triggers insulin release. The membrane is then repolarized through activation of KCa and Kv channels. Multiple KCa and Kv channel subtypes have been identified in insulin-secreting cells, with emerging evidence highlighting their significant modulatory roles in glucose-stimulated insulin secretion (GSIS). In this review, the current understanding and therapeutic potential of Kv channels in insulin secretion are discussed in relation to the structural features and physiological functions.
