Juvenile mice treated with MHC class II antibodies. (A) Total BAL cell counts were higher in LPS/MHC II and LPS/saline mice compared with saline/MHC II and saline/saline mice (*P < 0.001, **P < 0.001). (B) Representative example of lung in saline/saline (a), LPS/saline (b), saline/MHC II (c), and LPS/MHC II (d) mice. Arrows point to inflammatory cells in the lungs. (C) LPS/MHC II mice had significantly lower weights than LPS/saline mice (†P < 0.01), saline/MHC II mice, and saline/saline mice (*P < 0.001) at 4 days after LPS or saline aspiration (n = 7–9). Error bars represent mean ± SEM.
