B7x deficiency modulates macrophage populations in the spleen post-nephrotoxic serum (NTS) challenge. Macrophages were stained as described in the Materials and methods, and a total of 50 000 events were recorded per sample. Data are representative of two independent experiments, and are expressed as mean ± standard error of the mean (s.e.m.), n = 4 per group. *P ≤ 0·05, by unpaired t-test.
