BLR1 expression is maintained in the absence of TNF and LT. Spleen cells from WT C57BL/6, TNF−/−, and TNF/LTα−/− mice were dual labeled for B cells (PE anti-B220 mAb) and with either rabbit anti-BLR1 or as a control, rabbit IgG (10 μg/ml) followed by FITC anti– rabbit IgG. Histograms, BLR1 expression of B220+ cells. Dotted line, Rabbit IgG background staining of WT B220+ cells. Background staining of B cells from TNF−/− and TNF/LTα−/− mice was comparable to that of WT mice. Spleen cells derived from groups of three mice were examined individually, and similar results were obtained for each.
