IL4 and infection: While the fact that a number of DNBS + H. diminuta-treated mice bore five worms at 8-dpi is noteworthy, and something we have never seen in immunocompetent mice, there was a negligible impact on the Th2 response to infection, as gauged by blood eosinophilia, goblet cell hyperplasia, and spleen cell production of IL-4, -5, -10, and -13, and worms were not detected at 11-dpi.
