We developped two molecularly targeted peptide probes using a phage display method. The probes pass through the blood brain barrier (BBB) and are specifically incorporated into malignant glioma (GBM) cells when administered intravenously. The peptides were attached to the surface of nanoemulsions (NEs), and the NEs were encapsulated with anticancer agents to create molecularly targeted anticancer agents for GBM. The antitumor effect was confirmed in the patient-derived xenograft (PDX) model, in which human-derived GBM stem cells are transplanted into the mouse brain.
GBMの5年生存率は10%以下、平均余命は1~1.5年と予後不良である。この腫瘍は、浸潤性に進展するため切除範囲と脳の機能温存が対立し、手術で完全に摘出できない。血液脳関門(BBB)に守られ抗癌剤が届きにくい、という特徴があり、 ヒトのがんで最も治療が困難な疾患の1つである。研究者らは、頸静脈経由で腫瘍に特異的に輸送できるdrug delivery system(DDS)であるNEを開発した。本研究の特徴は、NE内に任意の抗癌剤を包埋できるので、多様な遺伝子変化をもつGBMに最も有効な抗癌剤カクテルを輸送できることにある。これまでに、このようなDDSの開発事例の報告はない。
