Fig. 4: Numbers intestinal eosinophils, but not lung eosinophils, remain elevated up to 11 days following skin allergen challenge.

a PBS-alum (sham) or OVA-alum sensitized mice received 3 consecutive epicutaneous challenges with PBS (sham) or OVA as in Fig. 1a with the modification that all mice were sacrificed on day 34 (11 days after the final skin allergen challenge). Intestinal (a) and lung (b) eosinophils were quantified from anti-MBP stained tissue sections. *p < 0.01.
