近日,来自大阪大学的研究人员通过研究鉴别出了一种新型的“分子机器”,这种分子机器能够在自噬作用的介导下来进行分泌作用,相关研究揭开了自噬除了进行降解作用外的一种重要角色,未来或将帮助研究人员进行深入的医学转化研究。

长期以来自噬作用就被认为是一种进行降解的唯一生理学过程,但本文研究中科学家们提出了自噬或许还具有能够帮助分泌的角色;文章中研究者所鉴别出的新型“分子机器”能够在自噬作用的帮助下同SNARE蛋白合作来分泌产生炎性因子—白细胞介素1β。

除了白细胞介素1β,诸如铁蛋白等蛋白质也能够在基于相同自噬分子机器的帮助下进行分泌,因此,研究者所鉴别出的新型自噬依赖性的分泌系统还能够促进多种“无领袖”蛋白的分泌,同时其在分泌过程中也扮演着重要作用。

研究者Tomonori Kimura说道,自噬作用和多种疾病的发生有着直接的关系,而且长期以来科学家们通过细胞内降解的角度来将自噬作用作为治疗的选择,本文研究中研究者就揭示了自噬作用的分泌角色,这就为后期科学家们开发治疗疾病的新型疗法提供了新的视角和线索。
