| abstractText | During investigating the expression of Gr-1 antigen on various subsets of mouse spleen cells, we found that Gr-1 was expressed on memory-type CD8(+)CD44(high)CD62L(high) T cells in addition to granulocytes. Intraperitoneal administration of anti-Gr-1 mAb caused almost complete elimination of Ly-6C(+) memory-type CD8(+) T cells as well as Ly-6G(+) granulocytes. Anti-Gr-1 mAb-treated mouse spleen cells exhibited greatly reduced IFN-gamma production in response to anti-CD3 mAb both in vitro and in vivo. This reduced cytokine production appeared to be derived from elimination of IFN-gamma-producing Gr-1(+)CD8(+) T cells. Indeed, CD8(+) T cells with IFN-gamma-producing activity and cytotoxicity were generated from isolated Gr-1(+)CD8(+) cells but not from Gr-1(-)CD8(+) T cells. We also demonstrated that therapeutic effect of MBL-2 tumor-immunized spleen cells was greatly reduced by anti-Gr-1 mAb-treatment. Thus, we initially demonstrated that anti-Gr-1 mAb might become a good tool to investigate a precise role for memory-type CD8(+) T cells in vivo. |
