摘要：

Exocytosis occurs in all eukaryotic cells. It involves the release of cellular biosynthetic products by fusion of the secretory organelle membrane with the plasma membrane. Whereas the general pathway of exocytosis is well established (Palade, 1975), many crucial aspects of the regulation of exocytosis are still poorly understood. This is particularly true for the specificity of membrane-membrane interactions (Palade, 1982) and for the regulation of the actual fusion process (Plattner, 1981; Parsegian et al , 1984; Lucy , 1985). This chapter discusses the results of our work on exocytosis in Paramecium as well as the implications of these results for exocytosis in general.
