TLR2 and infection: SNEA predicted 565 and 503 pathways for tlr2+/− and tlr2−/− zebrafish that are linked to the response to infection, respectively (Additional file 15: Table S4D and 4E), and 264 and 202 of them are specific for the response in tlr2+/− and tlr2−/− fish, respectively (Additional file 15: Table S4F).
