A lot has happened already in 2018. Besides teaching and writing grant proposals, a number of our papers have appeared in print. These include an original research article on the role of type-1 muscarinic receptors in the regulation of the acetylcholine-activated potassium current (in Int J Cardiol), as well as reviews on macromolecular complexes (in Herzschrittmacherther Elektrophysiol) and translational challenges in atrial fibrillation (in Circ Res). An overview of all publications can be found here.
