Fig. 4From: Maternal exposure to ultrafine particles enhances influenza infection during pregnancyRegulation of pro-viral and pro-inflammatory genes A Expression of Sphk1 between exposure groups, with the highest expression UFP-PR8 group; correlation analysis showed a strong positive correlation with viral titer (R2 = 0.8366). B Expression of Il-1β between exposure groups, with the highest expression in the UFP-PR8 group; correlation analysis showed a moderate positive correlation with viral titer (R2 = 0.6287). C Expression of Irf7 between exposure groups, with no significant changes or correlations with viral titer (R2 = 0.02653). D Expression of Tgf-β between exposure groups with no significant changes or correlations (R2 = 0.1602). E Expression of Il-33 between groups with no significant changes or correlations with viral titer (R2 = 0.1052)Back to article page
