CCL19 and infection: On the other hand, positive expression of chemokines (e.g., cxcf1b, ccl19a.1, ccl19, cxcl11) was also observed at 72 h and 120 h in gills and HK with enriched mechanisms and associated with “immune response”, “signaling receptor activator/regulator activity” and “cytokine/chemokine activity”, indicating that the pro-inflammatory activation of these molecules remains beyond the acute phase in order to help fight the infection.
