IFNB1 and infection: As shown in Figure 6, compared with PBS group, the levels of pulmonary IFN-β, IFN-γ, and IL-10 significantly increased at 3 or 5 days post-infection in the mice administered with live (P = 0.0425, P = 0.0111, and P = 0.0400) or pasteurized A. muciniphila (P = 0.0076, P = 0.0241, and P = 0.0126).
