CCL19 and infection: Furthermore, the novel_circ_0001830, novel_circ_0000627, novel_circ_0001881, and novel_circ_0003494 downregulated the expression of dre-miR-193a-3p, novel_187, dre-miR-210-5p, novel_685, and then the miRNA-targeted genes, including gap junction Cx32.2, glucagon-1, and CC chemokine (ccl19), were upregulated in the 96 h post-infection.
