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 ...

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 ...

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

Cell crowding causes high-grade breast cancer cells to become more invasive by activating a molecular switch that causes the cells to shrink and spread.

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 ...

This cytoskeletal stiffening and altered plasma membrane viscoelasticity undermine their ability to respond to mechanical signals, disrupting healthy bone remodeling and leading to bone fragility.
