Abstract
CD83, a cell surface membrane glycoprotein member of the Ig superfamily which is commonly used as standard surface marker for dendritic cells, was cloned from gilthead sea bream macrophages using degenerate primers against conserved motifs of known CD83 sequences. The obtained cDNA contains an open reading frame of 669 nucleotides that translate into a 222 amino acid putative peptide. The deduced protein sequence shows conservation of features shared by vertebrate CD83 and multiple alignment with fish CD83 sequences reveals high homology. In cultured sea bream macrophages CD83 mRNA expression was significantly enhanced in a dose- and time-dependent fashion after stimulation with Escherichia coli LPS. These results indicate that in fish, macrophages express high levels of CD83 mRNA after LPS exposure and CD83 is therefore a good marker for activated mature myeloid cells in fish.
