IL-37b expression among IL-37bWT and Variants in IL-37b transgenic mice. a The agarose gel confirms the IL-37b insert in IL-37WT, V1 and V1V2 transgenic mice which is absent in the background (control) WT strain. b IL-37b production in the blood cell lysates of tgIL-37WT, tgIL-37V1 and control mice. c Semi-quantitative band density analysis of IL-37b from panel b normalized to β-actin. Data are means ± SD (n = 3/group). ***p < 0.001(unpaired two-tailed Student’s t-test). d IL-37b production in the blood cell lysates of tgIL-37WT and tgIL-37V1V2 mice (n = 3/group). e IL-6 expression level in the supernatant of BMDM (Bone marrow-derived macrophage) from tgIL-37WT and tgIL-37V1 mice at various LPS concentrations. The results are expressed as the mean ± SD. **p < 0.01, ***p < 0.001 (One-way ANOVA and Sidak multiple comparisons test). Results are representative of three independent experiments. f BMDM IL-1β expression by tgIL-37WT and tgIL-37V1 mice at various LPS concentrations in presence of ATP. The results are expressed as the mean ± SD. *p < 0.05, ***p < 0.001 (One-way ANOVA and Sidak multiple comparisons test). (+) indicates the ATP stimulation for BMDM. Results are representative of three independent experiments. g The IL-1β expression level in the gingival tissues of ligature induced periodontitis model between IL-37WT and IL-37V1 transgenic mice group. The results are expressed as the mean ± SD (n ≥ 6/group). *p < 0.05 (unpaired two tailed Student’s t test). h Representative three-dimensional maxillary molars of IL-37WT and V1 transgenic mice in ligature induced periodontitis model. Scale bar is 0.5 mm. i The quantitative data of the distance from CEJ-ABC of first and second molar root in buccal side for each group. The results are expressed as the mean ± SD (n ≥ 5/group). (unpaired two tailed Student’s t test). *p < 0.05
