Secondary lysosomes dock only with phagoacidosome membrane at a distance of 40nm. As during acidosome fusion with phagosomes, fusion of the many lysosomes with the phagoacidosome occurs at nearly the ...

Vorticella convallaria fixed for EM and buffered in cacodylate. The rough ER is not vesiculated as it is in collidine buffered fixatives but appears as sheets from which Golgi dictyosomes arise. A foo...

This is one of six images in Figure 6 in Apaja et al., JCB 2010 that shows the fate of various model membrane proteins, that are either folded or in the unfolded state at the plasma membrane, expresse...

The acidosome-like vesicle has a bull’s eye appearance with the invagination appearing in the middle of the vesicle. Other vesicles contain multiple layers resembling multilipid layers. Two vesicles...

Stimulated Exocytosis. This micrograph shows the peripheral cytoplasm of a mammotroph in the pituitary of a lactating rat. Several secretion granules are lined up facing the perivascular spaces and a...

Cytochalasin B blocks DV release from cytopharynx. In this micrograph a very large nascent vacuole has been retained at the cytopharynx of this cell that had been exposed to cytochalasin B. Many acido...

The acidosome-like vesicle has at least 2 enclosing membranes or one membrane indented back on itself and an internal electron-opaque tongue-like droplet that is continuous with the enclosing membrane...

Acid phosphatase is present in tubules retrieved from late DV-III. The tubules and rounded expansions arising as a result of late DV-III membrane retrieval contain an electron-opaque reaction product ...

This image shows the heterogeneity in the content of lysosomes (Lys) near the plasma membrane between two hepatocytes and near the bile canaliculus (not visible in this field). Some of the lysosomes ...

Stimulated Exocytosis. This micrograph shows the peripheral cytoplasm of a mammotroph in the pituitary of a lactating rat. Several secretion granules are lined up facing the perivascular spaces and a...
