Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered ...

Here, a transport vesicle from the Golgi or elsewhere in the cell merges its membrane with the plasma membrane and releases its contents. In this way, membranes are continually recycled and reused ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

Substances are recycled back to the plasma membrane by transport vesicles that bud off from the endosomal tubular domains. What are the functions of endosomes? Endosomes play active roles in many ...

The vesicle travels to the cell membrane. The vesicle fuses to the plasma membrane, during which the two bilayers merge. The vesicle’s contents are released into the extracellular space. The vesicle ...

Most primary active transport is carried out by transmembrane ATPases, an enzyme that crosses the cell membrane. The sodium-potassium adenosine triphosphatase (ATPase) enzyme is found in all ...

Researchers from the National University of Singapore (NUS) have solved a 60-year-old mystery in bacterial cell envelope ...

Plants contain two major types of VAMP7 proteins: VAMP71, which functions in vacuolar membrane fusion, and VAMP72, which is involved in trafficking to the plasma membrane -- part of the secretory ...

Water is drawn through the membrane by forward osmosis, travelling across the nanobubble by evaporation and condensation. "We expect that this membrane will be useful for rejection of substances like ...
