We used quantitative RT-PCR to confirm that miR-451 is increased following influenza infection for 8 hours. miR-451 regulates dendritic cell cytokine responses to influenza infection. Inhibition of miR-451 expression correlated with increased YWHAZ protein expression and decreased ZFP36 expression, providing a possible mechanism for the elevated secretion of IL-6, TNF, CCL5/RANTES, and CCL3/MIP1 alpha.
