Fig. 1From: Exposure to combustion derived particulate matter exacerbates influenza infection in neonatal mice by inhibiting IL22 productionContinuous exposure to PM fails to sustain Il22 expression and inhibits Il22 expression after influenza infection in the lungs. Neonatal mice (age: 3 days) were exposed to aerosolized PM and infected with influenza or sham at 4 dpe. Lungs were collected at 0.5, 1 and 6 dpe and at 2 dpi. A Il22, B Il23 and C Cyp1a1 expression were measured using qRT-PCR. Data are normalized to vehicle-exposed 0.5 dpe group and vehicle-exposed non-infected group at 2 dpi. n = 3–5/group, *p < 0.05.
