The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

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 ...

Similar to a small cut that heals itself after a short time, individual cells in our body suffer "wounds" in their protective layer, the cell membrane, every day and have to repair them again.

To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane into the local environment. In a healthy cell, this can be a lifesaver: say, ...

Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

A new study shows how an anticancer drug triggers an "outside in" signal that gets it sucked into a cancer cell.

Every cell in the body normally has its fixed place as part of a tissue structure. Except for a few cell types, such as blood ...

Researchers at Linköping University, Sweden, have succeeded in creating a close connection between individual cells and ...

A new study shows how an anticancer drug triggers an 'outside in' signal that gets it sucked into a cancer cell. The work reveals a new signaling mechanism that could be exploited for delivering other ...

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 ...

Like a poison pen, dying cells prick their neighbors with a lethal message. This may worsen sepsis, Vijay Rathinam and ...
