研究人员在2020年9月15日出版的《生物物理杂志》上报告说，人类白细胞（即白血球）利用一种名为“分子划动”的新机制游泳。这种微小的游动机制可以解释免疫细胞和癌细胞是如何在体内各种充满液体的小生境中有益或有害迁移的。“活细胞自主移动的能力对许多生物学功能来说是迷人的，也是至关重要的，但是细胞迁移机制仍仅有一部分被理解。”该论文联合高级作者、法国艾克斯—马赛大学的Olivier Theodoly说，...

癌症虽不是一种游戏，但美国约翰·霍普金斯大学科学家正在从进化博弈理论的角度审视癌症的能量生产过程，研究肿瘤细胞之间是怎样互相合作的。他们的实验有望找到一个最佳时机，破坏转移性癌细胞之间的“伙伴关系”，让癌瘤变得更脆弱。相关论文发表在近日的英国皇家学会期刊《界面聚焦》上。
“目前我们还无法治愈转移性癌症，博弈论为我们攻克这一难题增加了筹码。”该校布拉迪泌尿学研究所泌尿学教授、基梅尔癌症中心前列腺癌...
