FOS and anaphylaxis: OIT + FOS protected against the anaphylaxis-associated drop in body temperature compared to sensitized control mice (p = 0.0045) and FOS no IT (p = 0.0123) (Figure 2B) and both OIT and OIT + FOS reduced the severity of anaphylaxis symptoms (Figure 2C) compared to the sensitized control (p = 0.0322 and p = 0.0002, respectively).
