FIGURE 3

Siglec-E-deficient DCs showed enhanced phenotypic maturation. (A–C) Flow cytometry analysis of the expression levels of several DC maturation markers on CtrV Sp37A3 cells (black) and EKO Sp37A3 cells (blue), including MHC-I (A), MHC-II (B), and CD40 (C). (D) treatment of CtrV Sp37A3 cells (black) and EKO Sp37A3 cells (blue) with neuraminidase and maturation with LPS was measured by the expression of MHC II. (E–G) Maturation markers on spleen and tumor-infiltrating cDCs isolated from MC38 subcutaneous tumor models of CD11ccreSigEfl mice (blue) and littermates (CD11cwtSigEfl, black) by flow cytometry. Data are presented as mean (±SD). Two-way ANOVA was used for two-way comparisons, and unpaired t test was used for one-way comparisons (*p < 0.0332, **p < 0.0021, ***p < 0.0002, and ****p < 0.0001).
