| \[摘要\]脂筏(lipid raft)和细胞的许多功能,如信号转导、蛋白质和脂类的转运等都相关。近来有研究发现,与多药耐药密切相关的ABC转运蛋白(ATP-binding cassette transporter)定位于脂筏中,因此推测脂筏可能与耐药性有一定关系。本文综述了3种和耐药相关的ABC转运蛋白的定位与其功能之间的联系,分别是和肿瘤细胞多药耐药相关的ABC转运蛋白Pgp/ABCB1、MRP1/ABCC1以及与白假丝酵母菌(白念珠菌)多药耐药相关的ABC转运蛋白Cdr1p；并进一步讨论了脂筏的重要组成成分胆固醇和鞘脂对上述3种ABC转运蛋白的定位和功能的影响。 |

| Abstract: |
| \[Abstract\]Lipid rafts have been implicated in many cellular functions, including protein and lipid transport and signal transduction. Recently ATP-binding cassette (ABC) transporters, which are associated with multidrug resistance, have been found in lipid rafts; therefore they might be related to drug resistance. Here we introduce the relationship between the localization and functions of three multi-drug related ABC transporters, including two relevant to multidrug resistance in tumor cells(Pgp/ABCB1 and MRP1/ABCC1) and one relevant to multidrug resistance in Candida albicans (Cdr1p). We also discuss the influence of sphingolipids and cholesterol, two major components of lipid rafts, on the localization and function of the above three ABC transporters. |
