Fig. 10From: Surface area-dependence of gas-particle interactions influences pulmonary and neuroinflammatory outcomesCytokine expression profile in the C57BL/6 hippocampus after chronic (30-day) exposure to atmospheres. After 30 days of exposure to atmospheres, cytokine mRNA expression was assessed in the hippocampus of the C57BL/6 mouse brain for the following: (a) Ccl5, (b) Cxcl1, (c) IL-6, and (d) Tgf-β. UFP exposure only increased (a) Ccl5 mRNA expression after thirty days, while UFP + G expression increased (d) Tgf-β. n = 7–8 per group, *p < .05; **p < .01; ***p < .001Back to article page
