パンテチン 10

上記成分及び分量をとり、第15改正日本薬局方製剤総則「注射剤」の項に準じて注射剤を製した。
1.実験方法
1)動物
BALB/cマウスは日本チャールスリバー(横浜)より購入し、5週齢の雄を使用した。
2)培地
RPMI1640培地(Gibco社製)に、非働化した牛胎児血清(Fetal Bovine Serum,DSファーマバイオメディカル株式会社)を10%になるように使用した。
3)薬剤
パンテチン(第一三共プロファーマ製)が0.167, 1.67,16.7, 167μg/mLになるように、さらに両薬物の併用されるように培地により希釈、調製した。また対照薬としてシクロスポリン(和光純薬製)10μg/mLを使用した。
4)脾臓細胞からCD4陽性T細胞(Th細胞)の分離
脾臓から脾細胞を分離し、溶血、白血球を分離した。さらにDynabeads FlowComp Mouse CD4(invitrogen社製)を用いてCD4陽性T細胞を分離した。
5)CD4陽性T細胞の刺激によるサイトカイン産生
調製したCD4陽性T細胞浮遊液(8×105 cells/mL)に、上記3)にて調製した薬剤に、Dynabeads Mouse T-Activator CD3/CD28(invtorogen社製)を4μL、IL-6 20ng/mL TGFβ 2ng/mL添加し、37℃、5% CO2存在下で3日間培養した(0.2ml/well)。その後、上清中に産生されるサイトカインを、ELISA法により定量した。その際、IL-17を、それぞれ定量した。ELISA法にはeBio science社製のサイトカイン測定キットを使用した。
結果を図1に示す。Dynabeads Mouse T-Activator CD3/CD28、IL-6、TGFβ添加により、IL-17が産生され、パンテチンは用量に依存してIL-17産生を抑制し、シクロスポリンのような非常に強いサイトカインの抑制が認められた。従って、パンテチンが本発明の目的たるTh17細胞分化抑制作用を有することが判明した。
