虽然胆固醇/鞘磷脂(RAFT)膜结构域在质膜中的存在得到了强有力的实验证据的支持,但这些结构域的结构、大小、动力学和分子组成仍有待了解。RAFT结构域被认为代表了脂双层的一种特定的物理状态,即液体有序相。最近的观察表明,在哺乳动物的质膜中,有序脂相中的小筏结构域与无序的膜环境处于动态平衡状态。通过蛋白质介导的RAFT相关成分的交联化,可以扩大和/或稳定RAFT。这些质膜结构的变化被细胞视为信号,很可能是免疫受体信号传递的重要因素。病原体滥用宿主细胞质膜上的RAFT结构域作为浓缩装置,作为信号平台和/或进入细胞的场所。要阐明这些相互作用,需要详细了解浮筏的结构和动力学。
While the existence of cholesterol/sphingolipid (raft) membrane domains in the plasma membrane is now supported by strong experimental evidence, the structure of these domains, their size, their dynamics, and their molecular composition remain to be understood. Raft domains are thought to represent a specific physical state of lipid bilayers, the liquid-ordered phase. Recent observations suggest that in the mammalian plasma membrane small raft domains in ordered lipid phases are in a dynamic equilibrium with a less ordered membrane environment. Rafts may be enlarged and/or stabilized by protein-mediated cross-linking of raft-associated components. These changes of plasma membrane structure are perceived by the cells as signals, most likely an important element of immunoreceptor signalling. Pathogens abuse raft domains on the host cell plasma membrane as concentration devices, as signalling platforms and/or entry sites into the cell. Elucidation of these interactions requires a detailed understanding raft structure and dynamics.
