Tirzepatide Regulates Pacemaker Function by Modulating cAMP and Calcium Dynamics in Human Sinoatrial Node Cells

Key Points

• The study aims to explore how tirzepatide influences pacemaker activity by altering cAMP and calcium dynamics in sinoatrial node cells.
• Conducted experiments on human sinoatrial node cells to assess pacemaker function.
• Measured changes in cAMP and calcium levels following tirzepatide treatment.
• Tirzepatide significantly increased cAMP levels, indicating enhanced signaling.
• Calcium dynamics showed improved regulation, enhancing pacemaker function.
