Background: Interleukin 8 is a chemokine that is produced by several types of cells, like macrophages and has chemotactic activity in particular on neutrophils, playing a key role during the inflammatory process. It has been demonstrated at the molecular level that this molecule is present and conserved in several vertebrate groups, pointing its importance. Analysis of the amino acid sequence of IL-8, projected from cDNA of Salmo salar, presents homology with the sequences of mammals, poultry and lamprey, indicating the presence of a homologous molecule in higher fish. However, there is no information at protein level, which allows characterizing the regulatory role of this molecule during the immune response in fish. Results: In this work, we designed and... |
