A unique feature of mucins is the heterogeneous array of glycan structures that decorate the polypeptide backbone, and these glycans have well‐established roles in influencing pathogenic organisms, including GI nematodes.10, 75 Mucin glycans have been highlighted to be significantly altered during multiple inflammatory responses within the intestine, including during infection with N. brasiliensis, T. spiralis, T. muris and H. polygyrus. The gene discussed is MUC5AC; the disease is infection.
