In zebrafish embryos and larvae, IL1β is induced in response to injury and infections, similar to humans, facilitating the recruitment of white blood cells to the inflammation site and modulating myelopoiesis through the NF-κB and CCAAT/enhancer-binding protein beta (C/EBPβ) signaling [133,134,135] (Figure 2). This evidence concerns the gene CEBPB and infection.
