[Lipids in the process of synaptic vesicle exo- and endocytosis].
The phenomenon of synaptic transmission is based on the processes of synaptic vesicle exo- and endocytosis carried out with complex protein-dependent mechanisms. The SNARE-complex forming proteins (synaptobrevin, syntaxin, SNAP-25), synaptotagmin, Munc13, Munc18, NSF, alpha-SNAP are involved in exocytosis, while the synaptic vesicle endocytosis is mediated by another protein (clathrin, AP-2, epsin, endophilin, amphiphysin, dynamin, synaptojanin, Hsc70). In recent years, data on critical role of various lipids in exo- and encocytosis are collected. Most interesting results are received about significance of the cholesterol, phosphoinositides, phosphatidic and polynonsaturated fat acids in the exo-endocytosis cycle. Participation of lipid rafts in synaptic vesicle recycling is discussed. In this article, the data of the last years, including the authors' own data about role of some lipids and lipid-modifying enzimes in processes of exo- and endocytosis are presented.
