For example, miRNA-124 suppressed macrophage activation by repressing the expression of CCAAT/enhancer-binding protein alpha (C/EBPα),202 miRNA-126 reduced the expression of PU.1 and thus TLR activation in allergic asthma.203 It is noteworthy that the same miRNAs may not act uniformly under distinct cellular contexts or pathologic conditions. Here, CEBPA is linked to allergic asthma.
