IL4 and ancylostomiasis: Similarly, there were higher numbers of mast cells (GLM.NB, clearance = 1.14 ± 0.25, Z = 4.6, p = 4.2×10−6) and more mucus (GLM, clearance = 0.03 ± 0.003, Z = 7.84, p = 9.4×10−10) in the mucosa, and more leukocytes expressing IL-4 in the intestine (GLM.NB, clearance = 1.97 ± 0.15, Z = 12.72, p = 2.0×10−16) and mesenteric lymph node (GLM.NB, clearance = 1.57 ± 0.11, Z = 14.63, p = 2.0×10−16) of pups that cleared hookworm infection when compared to controls and pups with hookworm enteritis and bacteremia.
