On April 14 2025 we launched the first seminar of the Leiden CardioVascular Medicine (LCVM) organization at Leiden University. The LCVM connects cardiovascular scientists from the LUMC, LACDR and Leiden University Campus in the Hague. Bram Slütter kicked off this meeting by introducing the exciting cardiovascular research that is currently being performed at the Faculty of Science of Leiden University. Followed by a very nice presentation of our current advances in understanding B cell immunity in atherosclerotic cardiovascular disease by B-specific member Jill de Mol. We closed this successful meeting with some nice drinks and good conversations!
