“…Unlike their counterparts in higher vertebrates, the fish CXCL8 homologues mostly lack the ELR motif at the N terminus of the mature peptide, with the exception of gadoid CXCL8_L1 molecules, as seen in Atlantic cod and haddock (Corripio-Miyar et al, 2007;Seppola et al, 2008). Homologues have also been described for the CXCL9-11 group in carp, catfish, rainbow trout and zebrafish, whereas their phylogenetic relationship within the CXCL9-11 group has not been conclusively established (Nomiyama et al, 2008;Baoprasertkul et al, 2004;Chen et al, 2010;Savan et al, 2003). In contrast, the existence of CXCL12, 13 and 14 homologues in teleost fish is much more certain, as documented by several research groups (Baoprasertkul et al, 2004;Huising et al, 2004;Tian et al, 2010).…”
