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 ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

We don’t know much about the regulation of endocytosis and cell-to-cell transport in the muco-ciliary epithelium of the upper respiratory tract. Viruses, on the other hand, know all about it. We use ...

These interfaces facilitate the efficient transfer of materials and information between cells, through the dynamic assembly of molecular platforms at the plasma membrane. Such platforms integrate ...

The plasma membrane has distinct regions called membrane ... and releasing sequestered factors that affect signaling or transport functions. The researchers isolated MCC microdomains from yeast ...
