Outline of Research at the Start

びまん性正中神経膠腫は小児能幹部に発生する予後不良な疾患であり新規治療法の開発が急務である。臨床応用に繋がる質の高い動物実験を行うため、びまん性正中神経膠腫の特徴を反映したモデル作成が重要である。腫瘍溶解ヘルペスウイルス療法は、腫瘍溶解による直接的な効果に加え、抗腫瘍免疫を誘導する治療法として期待されている。本研究においてはびまん性正中神経膠腫細胞を用いた試験管内実験とマウスモデルを用いた実験を行い、腫瘍溶解ヘルペスウイルス療法のびまん性正中神経膠腫への有効性を示し臨床試験へつなげる。

Outline of Final Research Achievements

We could stably maintain the murine diffuse midline glioma (DMG) cell lines that had H3.3K27M mutation in vitro. DMG cells mainly proliferated to form spheroid cell clusters, but some DMG cell lines easily differentiated to the adhesive cells. H3.3K27M mutant protein was indirectly confirmed with Green Fluorescent Protein (GFP) tagged to H3.3K27M structure. Also, H3.3K27M sequence was validated by Sanger sequencing. We could induced differentiation from the murine embryonal stem cells to brainstem organoid under the specific conditions. Co-culture with DMG cells and brainstem organoid made DMG cells more proliferative around the organoid. Oncolytic herpes virus had the cytotoxic effect in vitro against the DMG cells.

Academic Significance and Societal Importance of the Research Achievements

DMGは放射線療法が一時的な効果を示すのみで現時点で有効な治療法がない難治性の腫瘍である。DMGの治療が難しい理由として摘出が難しいこと、血液脳関門があり薬剤が腫瘍に到達できないことが挙げられる。腫瘍溶解ヘルペスウイルスは腫瘍内投与することで腫瘍細胞でのみ増幅して細胞障害性を示すことができる特徴がある。今回の実験で試験管内におけるDMGへの有効性は確認ができた。今後、さらに共培養条件下において腫瘍溶解ウイルスの有効性を確認し、さらに有効性を向上させる併用治療の開発ができれば臨床応用に向けて大きく先進すると期待される。
