Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them ...

A biomimetic nanoreactor coated with senescent stem cell membranes delivers nitric oxide and magnesium while scavenging reactive oxygen species, reversing a vicious cycle of cellular aging and ...

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 ...

The cells of higher organisms such as mammals, flies and fungi enclose their genetic material in a nucleus. A nuclear ...

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 ...

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.

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 targeted lipidomic study in engineered human astrocytoma cells found that Alexander disease-associated GFAP mutations caused distinct, extensive changes in lipid composition, with R239C producing ...

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 ...
