Endocytosis and exocytosis are the processes by which cells move materials into or out of the cell that are too large to directly pass through the lipid bilayer of the cell membrane. Large molecules, ...

In all eukaryotic cells, the constitutive processes of exocytosis and endocytosis maintain the flow of material to and from the cell surface. In secretory active cells, these processes have to be ...

Betz and colleagues find that dopamine triggers release of the dense core of secretory granules with prolactin during exocytosis. The dense core can contain signaling proteins, implying that both the ...

A team led by Scripps Research scientists has uncovered key details of an immune-cell process that frequently underlies excessive inflammation in the body. The findings could lead to new ways of ...
