Effect of age and oral OVA administration on antigen-induced BALF inflammation. Forty-eight hours after the final OVA challenge, BALF was collected for total cell differential count. Data expressed as mean ± SEM from combined data from two independent experiments (n = 5–7/group). (A) Total BALF cell count. (B) Total BALF eosinophil count. (Total numbers of mice: n = 10, 6-week non-fed/OVA; n = 9, 6-week OVA-fed/OVA; n = 11, 18-month OVA-fed/OVA; n = 5, 18-month non-fed/OVA; n = 6, 6-week naïve; and n = 5, 18-month naïve mice). *p < .05, **p < .01, ***p < .001.
