MUC5AC and infection: To identify the cytokine environment at time-points related to susceptibility to – and clearance of – infection and reduced mucin production, we investigated a panel of 23 cytokines and chemokines at the protein level in distal colon samples from WT and Fpr2−/− mice from day 0, 6 (low dose of C. rodentium), and 19 PI (conventional dose of C. rodentium).
