Supplemental Figure Legends Supplemental Figure 1. SemaB / mice have normal immune cell populations. Cells were prepared from the spleens of WT and SemaB / mice, stained with various antibodies and then analyzed by flow cytometry. Supplemental Figure 2. SemaB / T cells, B cells and DCs have normal proliferation, cytokine production and cellular interactions. A, B, Normal proliferative responses in SemaB / B cells and T cells. Splenic B cells from WT (open circles) and SemaB / (closed circles) mice were cultured with various concentrations of anti-μ or anti-cd for 36 h (A). Splenic CD + T cells from WT (open circles) and SemaB / (closed circles) mice were cultured with immobilized anti-cd3 with or without anti-cd28 for 8 h (B). [ 3 H] thymidine was added for the last 1 h. C, Th1/Th2 skewing was not impaired in SemaB / T cells. WT (open circles) or SemaB / (closed circles) naïve CD62L + CD + T cells were cultured under Th1- (left panel) or Th2- (right panel) skewing conditions for days. Then, CD + T cells were restimulated with immobilized anti-cd3 for 2 h. The cytokine concentrations in the culture supernatants were measured by ELISA. D, Normal cytokine production of SemaB / DCs. Splenic DCs (left panel) or BMDCs (right panel) from WT (open circles) or
SemaB / (closed circles) mice were stimulated with anti-cd for 8 h. The concentration of IL-12p in the culture supernatants was measured by ELISA. E, SemaB was not involved in normal MLRs between T cells and DCs. CD + T cells from BALB/c mice were cultured with irradiated allogeneic C7BL/6 WT (open circles) or SemaB / (closed circles) DCs for 6 h (upper panel). CD + T cells from C7BL/6 WT (open circles) or SemaB / (closed circles) mice were cultured with irradiated allogeneic BALB/c DCs for 6 h (lower panel). [ 3 H] thymidine was added for the last 1 h. Supplemental Figure 3. does not affect B cells, T cells and DCs in terms of proliferation, cytokine production and antibody production. B cell proliferation (A), B cell antibody production (B), T cell proliferation (C), splenic DC (left panel) and BMDC (right panel) cytokine production (D) and MLRs between CD + T cells and allogeneic DCs (E) were analyzed in the presence of (closed bars or circles) or (open bars or circles). F, did not affect DC-mediated Th1/Th2 differentiation. Naïve CD62L + CD + T cells derived from OVA-TCR Tg mice and BMDCs were cultured with OVA peptide for days in the presence of (closed circles) or (open circles). Then, CD + T cells were isolated and stimulated with
immobilized anti-cd3. The concentrations of IFN-γ (left panel) and IL- (right panel) in the culture supernatants were measured by ELISA. Supplemental Figure. affects basophils in a dose-dependent manner. BM-derived basophils were stimulated with IL-3 in the presence of various concentrations of (closed and semi-closed bars) or (open and semi-open bars) and then examined for IL- production. Supplemental Figure. SemaB / basophils have normal IL- production. WT (open bars) or SemaB / (closed bars) BM-derived basophils were cultured with IgE anti-dnp plus various concentrations of DNP-HSA for 16 h. The cytokine concentrations in the culture supernatants were measured by ELISA.
