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 ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed ...

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 ...

Gene regulation is the process by which cells control the expression of their genes, determining when, where, and to what extent each gene is expressed. It is a fundamental mechanism that allows cells ...

Bone health relies on a balance between osteoblasts (builders) and osteoclasts (recyclers). Peak bone mass occurs in early adulthood; deficiencies during this window amplify fracture risks later in ...

Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole ...

Other cells, such as glial cells, support the function of neurons. Neuroscience has often painted glial cells as the glue that holds neurons together, but glial cells can also be helpful in promoting ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.
