Splenic natural killer (NK) cells are reduced in abundance among interleukin (IL)-18BPKO mice. (A) Identification of splenic NK cells. Living, singlet events were selected from total splenocytes. After gating out debris, we selected lineage (CD3, CD19, Ly-6G), NK1.1+ events as NK cells. NK cell phenotype was confirmed with NKp46 labeling. Total splenocytes (B) were relatively similar between wild-type (WT) and IL-18BPKO mice, yet the proportion (C) and absolute number (D) of NK cells was significantly reduced among IL-18BPKO mice. Results from three unique experiments from six WT and eight IL-18BPKO mice. Bars represent median. Significance calculated with Mann–Whitney U test. **p < 0.01, ***p < 0.001, ns, not significant.
