Nat Commun:富含胶原的气道平滑肌细胞是肺中肿瘤定植的转移生态位

2019-05-24 AlexYang MedSci原创

转移是癌症死亡的主要原因。虽然转移级联反应的一些步骤已经研究的很详细,而阻断该过程的靶标的鉴定仍旧是一个挑战。决定转移定植到二级器官的宿主相关因素对探索靶标非常重要,这些宿主相关的因素在不同的癌症类型中也许是共享的。最近,有研究人员阐明了原发性肿瘤中,表达胶原蛋白受体的膀胱肿瘤细胞CD167a对胶原蛋白I刺激具有相应,并且能够促进局部入侵和使用相同的受体来倾向性的定植在平滑肌细胞(ASMCs)中。

决定转移定植到二级器官的宿主相关因素对探索靶标非常重要,这些宿主相关的因素在不同的癌症类型中也许是共享的。最近,有研究人员阐明了原发性肿瘤中,表达胶原蛋白受体的膀胱肿瘤细胞CD167a对胶原蛋白I刺激具有相应,并且能够促进局部入侵和使用相同的受体来倾向性的定植在平滑肌细胞(ASMCs)中。该平滑肌细胞是肺中胶原蛋白的一个丰富的来源。形态学上来讲,COL3-CD167a驱使的转移灶与典型的肺泡转移性病变明显不同,并且表现出了CD167a-HSP90-Stat3途径的激活。

最后,研究人员指出,重要的是,转移性肺定植也许可以用一种试验药物来减弱Stat3活性来阻止定植过程,表明了上述互作过程可以作为消除肺转移的治疗靶标。
