Inhibition of Pim1 kinase reduces intestinal responses. A, Kinetics of development of diarrhea. The incidence of diarrhea was significantly lower in inhibitor (100 mg/kg)-treated WT mice than in Runx3+/− mice (P< .05). B, Symptom scores were assessed 30 minutes after oral challenge. C, Plasma histamine levels were assessed within 30 minutes of the last oral challenge. D-G, Quantitation of mucosal mast cells, eosinophils, goblet cells, and CD4 and CD8 T cell numbers in the jejunum. Results were from 3 independent experiments; each experiment included 4 mice per group. *P< .05, **P< .01, and †P< .001. PBS/PE, Sham sensitized but PE challenged; PE/PE, PE sensitized and challenged.
