Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

Researchers from the University of Arizona have uncovered how a protein complex, known for regulating cell growth and ...

As people age, their immune system function declines. T cell populations become smaller and can't react to pathogens as ...

Metabolic reprogramming in the tumor microenvironment shapes immune function and therapy resistance, offering insights into ...

Scientists hoping to discover better ways to boost immune function — which could lengthen our healthspan and protect immunocompromised patients — may have a new target, according to findings published ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular ...

Mitochondria can lose power like batteries, but they can potentially be regenerated—a promising development than can be used in future treatments.
