Mini but mighty: Tiny WNT messengers help muscles grow

WNT signaling is crucial for the development of organisms and the maintenance of tissue homeostasis, since the WNT messengers are involved in a variety of cellular functions. In skeletal muscle, for example, they can increase ...

How a key immune protein is regulated in the cell

Scientists at EPFL have determined how a protein that is critical in our first line of immune defense is regulated in the cell to prevent autoinflammatory diseases.

A revolutionary method to observe cell transport

Membrane proteins are key targets for many drugs. They are located between the outside and inside of our cells. Some of them, called transporters, move certain substances in and out of the cellular environment. Yet, extracting ...

How a molecular switch shapes plant organ growth

Researchers at the John Innes Centre and partners at the Chinese Academy of Sciences have identified a molecular switch that establishes differential cell growth and organ shape.

Determining how and why cells make decisions

Cells are constantly making decisions that lead to differentiation. For instance, cells in an embryo make a series of decisions that determine whether they will become neurons in some cases and muscle cells in others. How ...

'Simple yet powerful': Seeing cell secretion like never before

We have recently witnessed the stunning images of distant galaxies revealed by the James Webb telescope, which were previously visible only as blurry spots. Washington University in St. Louis researchers have developed a ...
