Vascular normalization is an emerging concept in cancer treatment. In this issue of Cancer Cell, Rolny et al. show that histidine-rich glycoprotein normalizes tumor vessels and promotes antitumor immunity by polarizing tumor-associated macrophages, leading to decreased tumor growth and metastasis. Placental Growth Factor deletion in macrophages phenocopies many of these effects.
血管正常化是癌症治疗中的一个新兴概念。在本期《癌细胞》杂志中,Rolny 等人表明组氨酸丰富糖蛋白通过极化肿瘤相关巨噬细胞使肿瘤血管正常化,并促进抗肿瘤免疫,从而导致肿瘤生长和转移减少。巨噬细胞中胎盘生长因子的缺失可模拟许多这些作用。
