Development and Characterization of the Mode-of-Action of Inhibitory and Agonist Peptides Targeting the Voltage-Gated Sodium Channel SCN1B/β1 Subunit

Z. J. Williams, A. Alvarez-Laviada, D. Hoagland, L. J. Jourdan, S. Poelzing, J. Gorelik, R. G. Gourdie

This study identifies novel SCN1B mimetic peptides that can inhibit or promote β1-mediated adhesion, with effects potentially mediated through β1 RIP.

EXTRACELLULAR PERINEXAL SEPARATION IS A PRINCIPAL DETERMINANT OF CARDIAC CONDUCTION

W. P. Adams, T. B. Raisch, Y. Zhao, R. Davalos, S. Barrett, D. R. King, C. B. Bain, K. Colucci, G. A. Blair, A. J. Lozano, A. L. Hanlon, R. Veeraraghavan, X. Wan, I. Deschenes, J. Smyth, , S. Poelzing

This study investigates the relationship between cardiac conduction velocity and extracellular space structure, finding a biphasic relationship with perinexal separation, supporting ephaptic coupling over gap junction-based conduction.

The Calcium Transient Coupled to the L-Type Calcium Current Attenuates Action Potential Alternans

M. D. Warren, S. Poelzing

This study shows that calcium transients dampen action potential alternans, and their absence leads to more unstable alternans.

Acute adenoviral infection elicits an arrhythmogenic substrate prior to myocarditis

R. L. Padget, M. J. Zeitz, G. A. Blair, X. Wu, M. D. North, G. S. Hoeker, K. E. Stanley, C. M. Phillips, D. R. King, R. G. Gourdie, M. T. Tanenbaum, G. S. Hoeker, S. A. Swanger, S. Poelzing, J. W. Smyth

This study shows adenoviral infection causes arrhythmogenic changes in the heart before significant immune response, through gap junction and ion channel dysfunction.

Targeting the Cx43 Carboxyl Terminal H2 Domain Preserves Left Ventricular Function Following Ischemia-Reperfusion Injury

J. Jiang, J. A. Palatinus, H. He, J. Iyyathurai, J. L. Jourdan, D. Hoagland, G. Bultynck, Z. Wang, Z. Zhang, K. Schey, S. Poelzing, F. X. McGowan, R. G. Gourdie

This paper identifies that CT1's interaction with Cx43's carboxyl terminal H2 domain, not ZO-1, mediates its protective effects against ischemia-reperfusion injury in the heart.
