We warmly congratulate several of our colleagues on the publication in which they investigated whether neutrophil extracellular traps (NETs) and their regulator – peptidyl arginine deiminase 4 – play a role in the pathogenesis of adenine-induced chronic kidney disease (CKD) in an animal model. They found that the lack of gene expression of this regulator does not protect against the development of nephropathy, suggesting that NET formation is probably not directly involved in the pathogenesis of this CKD model. This study was the result of a long-term collaboration with leading pediatric nephrologist Ľudmila Podracká and Dr. Alexandra Gaál Kovalčíková from the National Institute of Pediatric Diseases in Bratislava and Associate Professor Diana Vavrincova-Yaghi and Associate Professor Peter Vavrinec from the Faculty of Pharmacy, Comenius University in Bratislava. Congratulation!
