Objective:

To examine the role of voltage-dependent potassium (Kv) channels in insulin secretion from pancreatic β-cells and their potential therapeutic implications in type 2 diabetes mellitus (T2DM), emphasizing their significance in glucose regulation.

Key Findings:

• Kv channels, particularly Kv2.1, play a crucial role in repolarizing the β-cell membrane, thereby regulating insulin release.
• Inhibition of specific Kv channels (e.g., Kv2.1) can enhance insulin secretion.
• Kv channels modulate the duration and amplitude of insulin release during glucose stimulation, impacting overall glucose homeostasis.

Interpretation:

Kv channels are essential for fine-tuning insulin secretion in response to glucose levels, suggesting their potential as therapeutic targets in T2DM management, particularly in enhancing insulin release.

Limitations:

• The review primarily focuses on rodent and human studies, which may limit the generalizability of findings to other populations.
• Further research is needed to fully understand the complex interactions between different potassium channels in β-cells and their implications for T2DM.

Conclusion:

Targeting Kv channels could represent a promising approach to enhance insulin secretion and manage T2DM more effectively, warranting further investigation into their therapeutic potential.
