Kloosterman and colleagues studied molecular and cellular changes during radiation therapy and disease recurrence across molecular subtypes of glioblastoma. They uncovered a distinct immune-cancer cell metabolic crosstalk during proneural/oligodendrocyte progenitor cell-like to mesenchymal-like transition, wherein macrophages feed on cholesterol-rich myelin debris to provide lipids to mesenchymal tumor cells, thereby fueling glioblastoma growth.
克洛斯特曼及其同事研究了胶质母细胞瘤的分子亚型在放射治疗和疾病复发过程中的分子和细胞变化。他们在神经前体细胞/少突胶质祖细胞样到间充质样转化过程中发现了一种独特的免疫-癌细胞代谢串扰,其中巨噬细胞以富含胆固醇的髓磷脂碎片为食,为间充质肿瘤细胞提供脂质,从而促进胶质母细胞瘤的生长。
