In TGs, the use of EGCG-AgNPs in uninfected controls resulted in a significant up-regulation of CXCL10 mRNA expression (p = 0.039) (Figure 6B), while upon infection at 3 days p.i., EGCG-AgNPs up-regulated mRNA expression levels for IFN-γ, CXCL9 and IL-1β (p ≤ 0.05), and down-regulated mRNA expression levels for CXCL10 and CXCL1 (p ≤ 0.05) (Figure 6B). The gene discussed is CXCL9; the disease is infection.
