Exposure to DE enhances influenza titers and IFN-β expression. A) Viral titers were quantified in lung homogenates as TCID₅₀ on day 1, 4, 8, and 14 p.i. B) IFN-β mRNA expression was quantified in lung RNA by RT-PCR. Values are normalized to β-actin and expressed as relative quantification. *significantly different from air exposed influenza infected mice (p < 0.05, n = 11).
