... of enzyme activities also showed that α -glucosidase, unlike other lysosomal enzymes, is mainly secreted via the apical pathway. Furthermore, immunocytochemistry showed the presence of a precursor form of α -glucosidase on the apical, but not the basolateral, membrane of the Caco-2 cells. We conclude that α...

...David L. Ebert; Kevin B. Jordan; Randall L. Dimond ABSTRACT Dictyostelium discoideum secretes a number of lysosomal enzymes during axenic growth and upon suspension in a low ionic strength, non-nutrient buffer (standard secretion conditions). These secretory characteristics have allowed us...

...A. TIEDTKE; L. RASMUSSEN; J. FLORIN-CHRISTENSEN; M. FLORIN-CHRISTENSEN The ciliate Tetrahymena thermophila releases lysosomal enzymes into nutrient and starvation media. We show here that this process occurs selectively, i.e. without leakage of cytoplasmic components, as indicated by lack...
