Sci Rep:通过损伤细胞外囊泡REG3β可改变肿瘤细胞的功能

2017-08-07 MedSci MedSci原创

细胞外囊泡(EVs),包括外泌体和微泡,均是含有蛋白质和核酸可作为细胞间信使的纳米级囊泡。EVs不仅在各种生理过程中起着重要作用,在炎症或癌症等病理情况下也起着重要作用。该研究表明,在胰腺导管腺癌(PDAC)的情况下,肿瘤周围正常胰腺组织可释放的REG3β——存在EVs表面连接糖蛋白的一种凝集素,从而干扰靶细胞的摄入和内化。在体外,由于REG3β的存在可扰乱EVs介导的通路,防止EV介导巨噬细胞的

细胞外囊泡(EVs),包括外泌体和微泡,均是含有蛋白质和核酸可作为细胞间信使的纳米级囊泡。EVs不仅在各种生理过程中起着重要作用,在炎症或癌症等病理情况下也起着重要作用。

该研究表明,在胰腺导管腺癌(PDAC)的情况下,肿瘤周围正常胰腺组织可释放的REG3β——存在EVs表面连接糖蛋白的一种凝集素,从而干扰靶细胞的摄入和内化。在体外,由于REG3β的存在可扰乱EVs介导的通路,防止EV介导巨噬细胞的表型转换,抑制癌细胞的迁移,并可反转EVs促进的代谢改变。在体内,肿瘤细胞摄取REG3β明显受损。此外,胰腺癌患者血液中循环REG3β+ EVs水平的增加。

总之,该研究结果强调肿瘤细胞周围健康胰腺组织释放的凝集素在调节EV介导的PDAC不同细胞类型之间关系的作用。

SCI REP:REG3β通过损害细胞外囊泡摄取来改变细胞肿瘤功能

细胞外囊泡(EVs),包括外来体和微泡,是含有蛋白质和核酸的纳米级膜囊泡,其作为细胞间信使发挥功能。它们在各种生理过程甚至病理状况,如炎症或癌症中起重要作用。在项研究中,我们发现,在胰腺导管腺癌(PDAC)中,肿瘤周围的健康胰腺组织释放REG3β,这是一种与EVs表面存在的糖蛋白结合的凝集素,因此这些细胞可以干扰其被靶细胞吸收和内化。
