FIG. 3.

Effect of anti-MIP-2 IgG administration on the total cell count and cell composition in BALF obtained from mice infected with PR8 virus. Infected mice received intracutaneous injections a total of two times (on days 0 and 1) with either 100 μg of anti-protein A IgG (white bar), 10 μg of anti-MIP-2 IgG (checkered bar), or 100 μg of anti-MIP-2 IgG (black bar) per day per mouse. On day 2 after infection, the total cell counts and cell compositions of BALF were examined. Each point shows the mean ± SD for five mice (SDs indicated by the error bars). An asterisk indicates that the value was significantly different from the control value (P < 0.01 by unpaired t test).
