In teleosts, the kidney is the major immune organ. From the kidney of fugu (Takifugu rubripes), we isolated a unique leukocyte population. This population shows properties similar to those of mammalian plasmablasts. First, adherent cells expressing IgM protein on their surface were obtained from the fugu kidney. Flow cytometry (FCM) showed that these cells were mainly composed of two cell populations: IgM(+)CD8α(-) cells and IgM(+)CD8α(+) cells. Further characterization of the IgM(+)CD8α(-) population by RT-PCR demonstrated that the cells expressed secretory-type IgM as well as Bcl-6 and Blimp-1, developmental marker genes for the B cell lineage. Western blotting also showed that the cells secreted IgM protein. These results indicate that the IgM(+)CD8α(-) cells are similar to cells at the plasmablast stage in mammals. This is the first report isolating plasmablast-like leukocytes in fish species. Our data also suggests that the teleosts kidney is a organ where B cells terminally differentiate into the plasma cells.
