The administration of butyrate had no effect (P ≥ 0.16) on expression of Th1 (Ifnγ, Tnfα)-, Th2 (Il4)-, and Th17 (Il17A, Il22)-associated cytokines or on expression of Myd88, Prg3, RegIIIγ, Tff3, and Tlr9 in mice without enteritis relative to mice that were not administered butyrate (data not presented). This evidence concerns the gene PRG3 and enteritis.
