- Upregulation of IL-1β, IL-12, and CXCL-10 expression - Survival analysis showed that tilapia fry fed on Epi-1-expressing Artemia cyst were survived longer upon S. iniae infection when compared with the fry fed on control cysts. Tilapia fry fed on Epi-1-expressing Artemia cyst survived for 5 days upon infection as compared to control group fry which generally died within 3 days of infection. This evidence concerns the gene CXCL10 and infection.
