TGFB1 and parasitic infectious disease: Increased susceptibility to a range of intestinal and tissue‐dwelling parasites can be seen in mice lacking essential elements of the type 2 response pathway.11 Likewise, in human populations, single nucleotide polymorphisms (SNPs) in type 2 response elements such as IL‐13 and STAT‐6, and immunoregulatory elements IL‐10 and TGF‐β correlate with both decreased susceptibility to allergy and increased susceptibility to parasitic infection.12, 13, 14
