DCIR2+ cDCs migrate from the marginal zone bridging channel to the T cell zone after immunization. Spleens from BALB/c mice (n = 2 per time point) immunized with 250 μg IgE anti-OVA pre-mixed with 100 μg OVA or with 100 μg OVA alone were harvested after 0.5, 4, 8, 24, or 48 h. One unimmunized mouse (Nil) was used as control. (a–k) Half of each spleen was snap-frozen and non-consecutive spleen sections were stained and analyzed by confocal microscopy. Localization of DCIR2+ cDCs in spleens harvested at indicated time points after immunization was followed. B220+ B cells, blue; CD169+ metallophilic macrophages, grey; DCIR2+ cDCs, red. Marginal zone bridging channels are indicated with arrows in (a,g). Images show representative areas (640 μm × 640 μm) of 3–4 T cell zones from 2 non-consecutive sections of each sample in every group. Scale bar represents 100 μm. Data represent one experiment where mice were immunized with IgE-OVA or OVA alone and one where they were immunized with IgE-OVA. (l) The other halves of the spleens from mice immunized with IgE-OVA complexes in (a–e) were prepared into single cell suspensions and 6 × 105 cells were used as APCs in co-cultures with 105 CFSE-labeled CD4+ T cells isolated from DO11.10 splenocytes. Percentages of divided cells among OVA-specific CD4+ T cells after incubation for 3 days with APCs taken from an unimmunized mouse (Nil) or from mice immunized with IgE-OVA complexes are quantified by flow cytometry as shown in Fig. 3. CD4+ T cells cultured alone were used as negative control. Each circle represents one mouse and the lines represent the mean values.

A fraction of BEC is CDH17+. (A) Spleens were treated with dispase and collagenase IV to obtain single stromal cells, and cell surface markers were analyzed by flow cytometry. Stromal cells were separated into four subpopulations: fibroblastic reticular cells (FRCs, gp38+CD31-), lymphatic endothelial cells (LEC, gp38+CD31+), BEC (gp38-CD31+), and double-negative (DN) cells (far right panel). Each fraction was then tested for CDH17 expression. The numbers adjacent to the gates indicate the percentage (%) of the indicated cells within their respective parental gates (shown on top of each panel). (B) The percentages of CDH17+ stromal cells within the respective parental gates are plotted on a bar graph. The percentages were calculated by subtracting the values of KO mice from those of WT mice (n = 7 (MAdCAM-1+ BEC); n = 8 (others)). *P≤0.05 (Student's t-test). (C) WT mouse spleen was stained with anti-CD169 (yellow), anti-MAdCAM-1 (green), anti-mouse IgG1 (blue), anti-CDH17 (red, BD1B), and analyzed by confocal microscopy. The middle-right micrograph is an enlarged view of the boxed area shown in the middle-left micrograph. The bottom row of images shows each separate color channel and an expanded view of the merged image shown within the box in the middle-right panel. The white arrowhead shown in the bottom right image indicates an IgG1+ cell that is adjacent to a CDH17+ cell in the MZ sinus. Data are representative of three independent experiments. Scale bars, 50 μm (top and middle row of images) or 10 μm (bottom row). (D) The localization of IgG1+ cells in the MZ, red pulp, and white pulp in WT and KO mice are plotted on a bar graph. Values are expressed as the percentage of IgG1+ cells localized within each sub-region of the spleen (n = 6; *P≤0.05 (Student's t-test)). (E) The number of MZ sinus (MAdCAM-1+) cells, CDH17+ cells, and CDH17+ MZ sinus cells (Cdh17+MAdCAM-1+) in the spleen of WT mice are plotted on a bar graph. Cell numbers were counted in six histological sections of WT spleen. The mean and standard deviation are plotted.

Increased number of neutrophils in the splenic white pulp of MCMV-infected WT male mice. WT or TLR9−/− male and female mice were left untreated of infected with 1×105 PFU of MCMV and 4 days later spleens were collected and processed for immunofluorescent analysis. (A) Murine spleen sections were incubated with antibodies specific to neutrophils (7/4, blue or red), B cells (B220, red), marginal metalophilic macrophages (MOMA-1, green) and reticular fibroblasts (ER-TR7, green). MCMV infection led to (A) a dramatic increase in the number of neutrophils that were present in the splenic red pulp and disappearance of the MZ metallophilic macrophages and (B) an increase in the number of neutrophils in the splenic white pulp areas compared to uninfected mice. These phenomena were more prominent in WT male than in WT female or TLR9−/− male and female mice. (B) Number of neutrophils per white pulp area were counted on slides stained in A. *** p<0.001. Data are representative of 9 mice per group.

IgM from BALB/c mice enhances germinal center responses. On day 0, BALB/c mice were immunized i.v. with WT or Cμ13 IgM specific for KLH (50 μg/mouse) or SRBC (0.2 ml of a solution with HA titer 1:32) 30 min before 10 μg KLH (A), 5×105 (B) or 5×106 SRBC (C) were administered via the same route; controls received antigens or specific IgM alone. Spleens were harvested on day 10. Splenocytes from half of each spleen were analyzed by flow cytometry; germinal center B cells were gated as GL7+PNA+ amongst B220+ cells (Figure S1) and the percentages of germinal center B cells were quantified (A-C, upper left panels). The other halves of the spleens were sectioned, stained with anti-B220 (blue), anti-MOMA (green) and PNA (red), and analyzed for number of PNA+ germinal centers in B cell follicles by confocal microscopy (A-C, upper right panels); each image is a representative area (1725 μm × 1295 μm) for 2-3 whole sections with original magnification ×10 (A-C, lower panels). Germinal center responses of mice immunized with specific IgM alone were always lower than the responses of mice immunized with antigens alone (not shown). Data are representative of two experiments with each antigen dose. ns = not significant; * = p < 0.05; ** = p < 0.01.

Effect of αGalCer treatment on activation and numbers of MZBs in vivo and in vitro. A–D. Four-mo-old female CD1d−/−, WT and Vα14Tg BALB/c mice were injected i.p. with 4 μg of αGalCer or vehicle. Their spleens were harvested 3–4 d later and analyzed by flow cytometry and immunohistochemistry for MZBs. Results using three mice per group from one representative of at least three independent experiments are shown. A. CD86 expression on gated CD19+CD21hiCD23−/low (MZBs) and CD19+CD21+CD23+ (FoBs) in αGalCer (thick line) or vehicle (shaded area) injected mice. B. MZBs (CD21hiCD23−/low) were analyzed on gated CD19+ lymphocytes. MZB frequency is expressed as % of CD19+ lymphocytes in representative dotplots (B) and as the mean±SE from three each of vehicle or αGalCer-injected WT, CD1d−/− and Vα14Tg mice (C). A significant reduction of MZBs was found in αGalCer-treated WT (*p<0.05) and Vα14Tg mice (**p<0.01), but not in CD1d−/− mice. D. Frozen spleen sections from αGalCer or vehicle treated mice were stained for APC-IgM (blue) and FITC-MOMA1 (green). Confocal images show IgM+ cells (blue) in the marginal zone between red pulp and MOMA-1 (green) in CD1d−/− and vehicle-injected Vα14Tg mice. IgM+ cells in the marginal zone are reduced in αGalCer-treated Vα14Tg mice (as indicated by a blue arrow). MZ, marginal zone; RP, red pulp; WP, white pulp. 20× and 40× magnification. E, F, Spleen cells (2×106 cells per ml) from 3-mo-old BALB/c mice were cultured with or without LPS in the absence or presence of αGalCer (100 ng/ml). Results represent five independent experiments, each time using cells from one mouse per group. E. Expression of CD69 and CD86 are shown on gated MZBs (CD19+CD21hiCD23−/low) in spleen cells cultured with medium alone (shaded area), αGalCer (blue line), LPS (green line) or LPS+αGalCer (red line) for 24 h. The MFI of CD69 and CD86 are shown. F. Spleen cells from WT and CD1d−/− BALB/c mice were cultured without or with LPS and/or αGalCer for 72 h. MZB cells are expressed as % of mature B cells (AA4.1− IgM+).

Spleens from BALB/c mice (n = 2 per time point) immunized with 250 μg IgE anti-OVA pre-mixed with 100 μg OVA or with 100 μg OVA alone were harvested after 0.5, 4, 8, 24, or 48 h. One unimmunized mouse (Nil) was used as control. (a–k) Half of each spleen was snap-frozen and non-consecutive spleen sections were stained and analyzed by confocal microscopy. Localization of DCIR2+ cDCs in spleens harvested at indicated time points after immunization was followed. B220+ B cells, blue; CD169+ metallophilic macrophages, grey; DCIR2+ cDCs, red. Marginal zone bridging channels are indicated with arrows in (a,g). Images show representative areas (640 μm × 640 μm) of 3–4 T cell zones from 2 non-consecutive sections of each sample in every group. Scale bar represents 100 μm. Data represent one experiment where mice were immunized with IgE-OVA or OVA alone and one where they were immunized with IgE-OVA. (l) The other halves of the spleens from mice immunized with IgE-OVA complexes in (a–e) were prepared into single cell suspensions and 6 × 105 cells were used as APCs in co-cultures with 105 CFSE-labeled CD4+ T cells isolated from DO11.10 splenocytes. Percentages of divided cells among OVA-specific CD4+ T cells after incubation for 3 days with APCs taken from an unimmunized mouse (Nil) or from mice immunized with IgE-OVA complexes are quantified by flow cytometry as shown in Fig. 3. CD4+ T cells cultured alone were used as negative control. Each circle represents one mouse and the lines represent the mean values.

Rat anti Mouse CD169, clone MOMA-1 recognizes murine CD169, also known as sialoadhesin or Siglec-1. CD169 is a lectin-like receptor expressed by certain populations of macrophages including marginal zone metallophils of the spleen, subcapsular macrophages of lymph nodes and stromal macrophages in bone marrow (Morris et al. 1991).
CD169 is a ~185 kDa sialic acid binding receptor containing 17 immunoglobulin-like domains (Crocker et al. 1992). Expression of CD169 can be induced on macrophages in culture by a serum factor and further modulated by cytokine exposure (McWilliam et al. 1992).
Rat anti mouse CD169, clone MOMA-1 has been used for the in vivo depletion of specific macrophage populations (Kraal et al. 1988).
