C57BL/6マウス(SLC、雄、10〜12週齢)から大腿骨を取り出し、RPMI1640培地中で大腿骨の両端を切断して骨内部にある骨髄組織を取り出した。26Gシリンジを用いて、この骨髄組織を単一細胞化して、C57BL/6マウス骨髄細胞を得た。
C57BL/6マウス骨髄細胞は、20ng/mLのGM−CSF(Peprotech、由来:ラビット)及び20ng/mLのIL−4(Peprotech、由来:ラビット)を含む10%FCS−RPMI1640培地で7日間培養して樹状細胞に分化させ、その後20ng/mLのTNF−α(Peprotech、由来:ラビット)を添加して成熟させた。NK026680処理は、培養2日目及び4日目に50ng/mL、6日目に250ng/mLを添加して行った。
C57BL/6マウス(SLC、雄、10〜12週齢)から脾臓を取り出し、脾臓内から脾臓細胞をRPMI1640培地中で取り出し、26Gシリンジを用いて単一細胞化してC57BL/6マウス脾臓細胞を得た。C57BL/6マウスT細胞は、C57BL/6マウス脾臓細胞からナイロンウール(R&D systems)を用いて分離採取した。
C57BL/6マウス脾臓細胞を超音波粉砕器で粉々にし、−80℃に凍結させた。その後解凍し、遠心(300g・5分)にて細胞破片を除去し、その上清を抽出液とした。
C3He/Jマウス(SLC、雄、10〜12週齢)から大腿骨を取り出し、RPMI1640培地中で大腿骨の両端を切断して骨内部にある骨髄組織を取り出した。26Gシリンジを用いて、この骨髄組織を単一細胞化してC3He/Jマウス骨髄細胞を得た。
C3He/Jマウス骨髄細胞は、20ng/mLのGM−CSF及び20ng/mLのIL−4を含む10%FCS−RPMI1640培地で7日間培養して樹状細胞に分化させた。NK026680処理は、培養2日目及び4日目に50ng/mL、6日目に250ng/mLを添加して行った。また、6日目に、C57BL/6マウス脾細胞抽出液も加えた。
BALB/cマウス(SLC、雄、10〜12週齢)から脾臓を取り出し、脾臓内から脾臓細胞をRPMI1640培地中で取り出し、26Gシリンジを用いて単一細胞化してBALB/cマウス脾臓細胞を得た。この脾臓細胞を超音波粉砕器で粉々にし、−80℃に凍結させた。その後解凍し,遠心(300g・5分)にて細胞破片を除去し、その上清を抽出液とした。
C57BL/6マウスから採取した骨髄細胞由来の樹状細胞にBALB/cマウス由来の脾臓細胞抽出液を加えてBALB/c抗原を提示させた。BALB/c抗原取込効果は、BALB/cの主要組織適合性抗原(MHC)であるI−Ad(抗体:BD pharmingen)の発現をフローサイトメトリーで測定することで確認した.この際、NK026680の存在下、非存在下で培養した後、TNF−α(Peprotech、由来:ラビット)で成熟させた。フローサイトメトリーによる成熟樹状細胞マーカー発現解析により、樹状細胞の成熟を確認した)。本発明のNK026680処理樹状細胞(NK−DC)と未処理の樹状細胞(CTR−DC)における共刺激分子CD40、CD80及びCD86の蛍光標識抗体を反応させ、フローサイトメトリーで平均蛍光強度(MFI)を測定することによりCD40、CD80及びCD86の発現量を比較した。
本実施例2では、実施例1と同様にC57BL/6マウス骨髄細胞から分化成熟させた本発明のNK026680処理樹状細胞と未処理の樹状細胞を得た。TNF刺激後24時間培養して得た培養上清を採取し,免疫応答刺激サイトカインIL−6及びIL−12p40濃度をELISA(BD bioscience)で測定した(n=3)。
本実施例3では、実施例1と同様に、C57BL/6マウス骨髄細胞から分化成熟させた本発明の制御性樹状細胞であるNK026680処理(NK−DC)と未処理の樹状細胞(CTR−DC)を得た。また、C57BL/6マウス骨髄細胞から樹状細胞に分化させた後実施例1と同様にBALB/c抗原を提示させたが、TNF−αによる成熟を行わなかった未成熟樹状細胞(unstim−DC)も得た。これら3種の樹状細胞に対して、それぞれC57BL/6マウスT細胞を混合した後、3H−TdR(GEヘルスケア)の取り込みを測定した。3H−TdRの取り込み量は、樹状細胞の異系抗原に対するT細胞の活性化誘導能を示す。
本実施例4では、C3He/Jマウス骨髄細胞由来の樹状細胞にC57BL/6マウス脾臓細胞の抽出液を加えてC57BL/6抗原を提示させた。C57BL/6抗原取込効果は、BALB/cのMHCであるI−Ab(抗体:BD pharmingen)の発現をフローサイトメトリーで測定することで確認した.この際、NK026680の存在下、非存在下で培養した。NK026680処理(NK−DC)と未処理の樹状細胞(CTR−DC)をそれぞれC3He/Jマウス(SLC、雄、10〜12週齢)に静脈内投与して移入した(投与数 3×106個/匹、媒体:燐酸緩衝塩液(PBS))。この際、樹状細胞を移入しない群(No−treat)も準備した(n=6)。7日後に、NK−DC移入群、CTR−DC移入群及びNo−treat群に、C57BL/6マウス(SLC、雄、10〜12週齢)の心臓を移植して3群の生存率を比較した。
