Marginal zone B cell regions were narrowed in Ziz2 KO mice. (A) Spleen sections were stained with anti-B220 (Red) and anti-CD169 (Green) antibodies for the MZ B cell region (B220-positive region outside CD169-positive cells). All mice were 10 weeks old. Scale bars: 100 μm. (B) MZ B cell regions were narrower in Ziz2 and Ziz3 KO mice than in wild type mice. (C) The proliferative activity of MZ B cells in response to LPS was not altered in both KO mice. Three mice per group were used. Data from three independent experiments (one mouse per group per experiment was used) were summarized. (D) The migratory activity of MZ B cells was analyzed using a transwell and flow cytometry. Activity against BLC or SDF1 (SDF) was not altered in both KO mice. Four mice per group were used. Each plot indicates data from one mouse. Data from four independent experiments (one mouse per group per experiment was used) were summarized. 2KO: Ziz2 KO. 3KO: Ziz3 KO. ***: P < 0.0001.
