摘要
溶酶体(lysosome)是细胞内重要的细胞器,参与细胞代谢、迁移、死亡等过程。溶酶体上表达的多种离子通道(ion channel)是溶酶体生理功能的基本保障,它们对维持溶酶体pH稳态、钙离子稳态、膜电位、融合、分裂、外泌及重新生成等过程具有非常重要的作用。溶酶体离子通道参与多种疾病的发生发展过程,并被认为是某些疾病药物治疗的潜在新靶点。本文总结了溶酶体上五种阳离子通道(TRPML1、TPC、TMEM175、BK、P2X4)的生理、病理功能的研究进展,并探讨后续靶向这些溶酶体离子通道的药物研发的可行性。
Lysosome is one of the important organelles in cells,which participates in various biological processes,including cell metabolism,migration,and death.Recently,lysosome has been found equipped with lysosome ion channels that play fundamental roles in maintaining lysosome physiologies.Lysosome ion channels are critical for a variety of characteristics of the lysosome,such as lysosomal pH,calcium homeostasis,membrane potential,fusion,fission,exocytosis,biogenesis,and so on.The deficiency of lysosome ion channels is usually related to a series of human diseases.They are exhibiting potential in drug development.Herein,we summarize the channel properties,and physiological and pathological functions of the five cation channels,TRPML1,TPC,TMEM175,BK,P2X4,on lysosomes,and discuss the feasibility of drug development targeting these channels.
