A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and ...

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

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

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 ...

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but ...

Counting non-empty cellsThe COUNTBLANK-COUNTA conflict (and how to fix it)Summary: Choosing the right counting functionIn ...

For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules ...

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 ...

Researchers have found a way to revive tired or damaged cells by giving them a fresh supply of mitochondria, the tiny ...

Researchers at Duke University used CRISPR technologies to discover previously unannotated stretches of DNA in the ‘dark genome’ that are responsible for controlling how cells sense and respond to the ...
