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 prokaryotes, ...

The laboratory of Ege Kavalali, professor and chair of the Department of Pharmacology, published a paper in Nature Communications that determined that liquid-liquid phase separation plays a key role ...

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.

A cell can suddenly form a large rounded pocket on its surface, as if its membrane were swelling locally. Researchers at RIKEN have reproduced this behavior in highly simplified artificial cells. The ...

Cellular membrane proteins play important roles in cellular transport, signaling, and cell-to-cell communication. Malfunction in membrane proteins can lead to serious diseases, such as cancer. However ...

SLCs act as both gatekeepers and workhorses at cell membranes. They determine what enters the cell and when: sugars that provide energy, amino acids ...

Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and St. Jude Children's ...

Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

A three-dimensional model of different organelle membranes created from high-resolution imaging data reveals that membranes vary in thickness. Darker colors indicate thicker regions of the membrane, ...

In every living cell, there are membranes—and in every membrane there are proteins, each of which acts as a chemical gatekeeper. Rather than passively letting ions pass in and out of the cell, these ...
