To test whether Dnm2 wt/K562E mice display also signs of neutropenia, we evaluated blood samples of naïve Dnm2 wt/K562E mice and controls for CD4+ T cells, CD8+ T cells, B cells, neutrophils, inflammatory monocytes, macrophages and dendritic cells (Fig. 8A). This evidence concerns the gene DNM2 and Decreased total neutrophil count.
