Ion channel activity drives ion channel expression.

Optical control of an ion channel gate.

The powerful optogenetic pharmacology method allows the optical control of neuronal activity by photoswitchable ligands tethered to channels and receptors. However, this approach is technically demanding, as it requires the design of pharmacologically active ligands. The development of versatile technologies therefore represents a challenging issue. Here, we present optogating, a method in whic...

Ion Channel Trafficking: Control of Ion Channel Density as a Target for Arrhythmias?

The shape of the cardiac action potential (AP) is determined by the contributions of numerous ion channels. Any dysfunction in the proper function or expression of these ion channels can result in a change in effective refractory period (ERP) and lead to arrhythmia. The processes underlying the correct targeting of ion channels to the plasma membrane are complex, and have not been fully charact...

Mathematical Modeling from Ion Channel to Ecg: an Introduction

Mathematical modeling plays an important role in cardiac electrophysiology. The purpose of this paper is to outline what the present state of computer hardware and algorithm development permits us to model, and to show how mathematical models help us to understand the pathophysiology of the heart.
