IL4R and ear infection: Overall, our data suggested that while IL-4Rα-responsive keratinocytes were not contributing to the development of the lesions or overall T helper immune responses of KRT14cre IL-4Rα−/lox BALB/c mice in the ear infection model, parasite replication at the site of the L. major LV39 infection was more controlled in these mice than in littermate control IL-4Rα−/lox BALB/c mice.
