Expression of inducible CC chemokines in rainbow trout (Oncorhynchus mykiss) in response to a viral haemorrhagic septicemia virus (VHSV) DNA vaccine and interleukin 8

In rainbow trout (Oncorhynchus mykiss), at least three CXC   chemokines and eighteen CC chemokine sequences have been discovered   in the past years, although no studies concerning their bioactivity   have been performed yet. We have studied the expression of five   different CC chemokines that cluster into the group of inducible   chemokines (CK5A, CK5B, CK6, CK7A and CK7B) in trout injected with a   plasmid coding for the glycoprotein G gene (pMCV1.4-G) of viral  haemorrhagic septicemia virus (VHSV). In a previous work, we had   demonstrated that a plasmid coding for the CXC chemokine interleukin   8 (IL-8, pIL8+) when co-administered with pMCV1.4-G was able to   modulate the expression of induced pro-inflammatory cytokines,   therefore, we have also studied the expression of these inducible CC   chemokines in fish injected with pMCV1.4-G in the presence of pIL8+,   study that will also help establish the relations among the  different chemokine groups. All chemokines were induced in the head   kidney of fish injected with the DNA vaccine, and the co-  administration of pIL8+ together with the vaccine modulated the   expression of all CC chemokines studied. In this sense, expression   of the inducible CC chemokines was also studied in trout head kidney   leucocytes treated with supernatants from EPC cells transfected with   pIL8+. In this case, all CC chemokines studied except for CK5B were  significantly induced by rainbow trout IL-8.    (VHS); (VHSv); (viral hemorrhagic septicemia); (viral haemorrhagic   septicaemia); (viral hemmorrhagic septicemia)
