AB - Interleukin-10 (IL-10) is an important immunoregulatory cytokine
produced by various types of cells. Researchers describe here the isolation
and characterization of olive flounder IL-10 (ofIL-10) cDNA and genomic organization.
The ofIL-10 gene encodes a 187 amino acid protein and is composed of
a five exon/four intron structure, similar to other known IL-10 genes.
The ofIL-10 promoter sequence analysis shows a high level of homology in putative
binding sites for transcription factors which are sufficient for transcriptional
regulation ofIL-10. Important structural residues are maintained in the ofIL-10
protein including the four cysteines responsible for the two intra-chain disulfide
bridges reported for human IL-10 and two extra cysteine residues that exist
only in fish species. The phylogenetic analysis clustered ofIL-10 with other
fish IL-10s and apart from mammalian IL-10 molecules. Quantitative real-time
Polymerase Chain Reaction (PCR) analysis demonstrated ubiquitous ofIL-10
gene expression in the 13 tissues examined. Additionally, the induction of ofIL-10
gene expression was observed in the kidney tissue from olive flounder infected
with bacteria (Edawardsiella tarda) or virus (Viral Hemorrhagic Septicemia
Virus; VHSV). These data indicate that IL-10 is an important immune regulator
that is conserved strictly genomic organization and function during the evolution
of vertebrate immunity.
