Lung tissue eosinophil infiltration. (A) Total numbers of eosinophils/mm² of lung tissue. (B) Eosinophils/mm² of perivascular tissue. Statistical significance was determined using the unpaired Student's t test (two tailed). *P < 0.05, ** P < 0.01, and *** P < 0.001 versus values for identically treated WBB6F₁-+/+ mice; ^† P < 0.05, ^†† P < 0.01, and ^††† P < 0.001 versus values for identically sensitized but saline-challenged mice (shown as mice challenged with “0” OVA) of the same genotype. Numbers of mice per group: n = 10 for BMCMC →W/W^v and n = 10 for W/W^vor +/+ in the OVA/alum groups, and n = 24–32 for W/W^v or +/+ in the OVA groups.
