Goblet cell hyperplasia in N. brasiliensis infection. A) Goblet cell quantification naïve mice and N. brasiliensis infected BALB/c (solid bar), IL-4Rα-/- (open bar) and IL-4/IL-13-/- (gray bar) mice 7 days and 10 days PI in small intestine sections. B) Intestinal adult worm burden 7 and 10 days post infection. Data representative of two experiments are shown.
