Loss of developmentally derived Irf8+ macrophages promotes hyperinnervation and arrhythmia in the adult zebrafish heart

Shannon E. Paquette, Cliff I. Oduor, Amy Gaulke…·Jessica S. Plavicki

This study shows that loss of Irf8+ macrophages in zebrafish leads to cardiac arrhythmia, dysfunction, and hyperinnervation.
