Abstract

CCAAT/enhancer binding protein alpha (C/EBPα) is a transcription factor that influences immune cell fate and differentiation. However, the effect of C/EBPα on mast cells is not fully understood. In this study, we showed that C/EBPα suppressed granule formation in mast cells and increased macrophage inflammatory protein (MIP)-2 production from mast cells upon bacterial stimulation. These results indicate that C/EBPα regulates the balance between the allergic response and the innate immune response of mast cells. Furthermore, we showed that stimulation of mast cells with the Lactobacillus casei JCM1134^T strain during late differentiation up-regulated C/EBPα expression in differentiated mast cells. This suggests that intestinal commensal bacteria modulate C/EBPα expression and thereby regulate mast cell function.
