中文摘要The genomic and cDNA sequences of the CD3 gamma/delta and CD3E > homologues in the mandarin fish, Siniperca chuats i, were determined. As in other vertebrate CD3 molecules, the deduced amino acid sequences of mandarin fish CD3 gamma/delta and CD3E > contained conserved residues and motifs, such as cysteine residues and CXXC and immunoreceptor tyrosine-based activation motifs. However, mandarin fish CD3 gamma/delta and CD3E > showed some differences to their mammalian counterparts, specifically the absence of a negatively charged residue in the transmembrane region of CD3 gamma/delta. Additionally, while an N -glycosylation site was present in CD3E >, the site was not observed in CD3 gamma/delta. The CD3 gamma/delta and CD3E > subunit sequences contain six and five exons, respectively, consistent with homologues from Atlantic salmon, Salmo salar. Phylogenetic analysis also revealed that CD3 gamma/delta and CD3E > in mandarin fish are closely related to their counterparts in Acanthopterygian fish. Real-time PCR showed CD3 gamma/delta and CD3E > were expressed mainly in the thymus and spleen in normal healthy fish and, to a lesser extent, in mucosal-associated lymphoid tissues, such as the intestine and gills. When lymphocytes isolated from head kidney were treated with the mitogens phytohemagglutinin, concanavalin, and polyriboinosinic polyribocytidylic acid, mRNA expression levels of CD3 gamma/delta and CD3E > were significantly elevated within 12 h of treatment. This indicated the presence of T lymphocytes in the head kidney of teleost fish, and also the recognition of mitogens by the lymphocytes. Mandarin fish infected with the bacterial pathogen Flavobacterium columnare also showed an increase in the expression of CD3 gamma/delta and CD3E > mRNA, indicating that CD3 gamma/delta and CD3E > lymphocytes are involved in the immune response of this species.
