The fibrogenic genes were downregulated in S. japonicum–infected TCR δ KO mice. a-d Real-time RT-PCR measurement of mRNA transcripts of collagen I (a), TGF-β (b), IL-17A (c), and IL-13 (d) in WT and KO mice at 6 weeks post-infection. e Adult worms in WT and KO mice at 6 weeks post-infection. f Hepatic egg burden in WT and KO mice at 6 weeks post-infection. Differences were analyzed by using Student’s t-test, n = 3 or n = 5 per group, *P < 0.05, **P < 0.01. Abbreviations: ns, no significant difference; EPG, egg per gram
