Figure 3. TRAF6 is required for mature B cell homeostasis.

Figure 3

(a) Flow cytometric analysis of BM from control and TRAF6-ΔB mice stained with the indicated antibodies (top-most and middle panels). The percentages of encircled areas are indicated. Pro+Pre, pro-B and pre-B cells; Imm, immature B cells; Rec, recirculating B cells. Results are representative of 5 mice. Lowest panel, absolute cell numbers; *, p<0.005. (b) Similar analysis of total spleen cells. Total B cells are shown in the topmost panels; mature (Mat) and immature (Imm) B cells are compared in the middle panels. The lowest panels compare the follicular (FO) and MZ sub-populations within the mature B cell gate shown in the middle panels. Cell numbers of each B cell subset in the spleen are shown in the lowest panels. Results are representative of at least 4 mice; *, p<0.05. (c) Splenic microarchitecture visualized by immunohistochemical staining with anti-B220 (red), anti-CD3 (blue) and anti-MOMA1 (green) antibodies. Results are representative of at least 5 mice.
