上皮间质转化与M2型巨噬细胞驱动小鼠和人肉瘤样尿路上皮癌的侵袭性
Epithelial to mesenchymal transition and M2 macrophages drive aggressiveness in murine and human sarcomatoid urothelial carcinoma.
导读
研究人员建立三个新型变异亚型膀胱癌细胞系,其中BBN966被病理学家鉴定为肉瘤样尿路上皮癌(SUC),其上皮间质转化通路上调最显著、M2型巨噬细胞基因表达比例最高,与人和犬SUC特征一致。在迄今最大规模PD-L1免疫组化队列中,38例人SUC有20例(52.6%)CPS>50;相应地,抗PD-1免疫检查点抑制剂可显著抑制BBN966肿瘤生长,为SUC新疗法转化研究提供临床前模型。
