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 ...

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.

In a breakthrough with promising real-world applications, a team of Rutgers biophysicists, bioengineers, and plant biologists ...

Image Credit: ART-ur/Shutterstock.com The plasma membrane is the outer layer of a cell, separating it from its environment and regulating molecular exchange. It consists of a lipid bilayer with ...

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 ...

Discover how a structural breakthrough in the chikungunya virus is opening new avenues for antiviral drug development and ...

Researchers knew, for instance, that HIV wraps its core viral components in a lipid envelope formed from the host plasma membrane. However, they were uncertain about how HIV controls the remodeling of ...

Cells are surrounded by a membrane - the plasma membrane - which acts as a physical barrier but must also be malleable. These ...

Membrane proteins have been found to contain hidden pathways that can be exploited to alter cell behavior, potentially leading to the development of new or improved drugs.

A new approach to elucidate the operation and control of Polymer Electrolyte Membrane (PEM) fuel cells is being developed. A global reactor engineering approach is applied to PEM fuel cells to ...

Aquaporins are proteins that rapidly transport water across cell membranes while excluding salt. They are critical for maintaining the right balance of water inside and outside cells and for ...
