IFNB1 and Hepatic fibrosis: Quantification of liver fibrosis demonstrated that the proportions of liver fibrosis in the control and IFNβ complemented mice were 45.00 ± 11.16% and 47.80 ± 14.39%, respectively (p = 0.7399) (Fig 4I and 4J), suggesting that IFNβ does not affect liver fibrosis formation during S. japonicum infection.
