A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and disease. Cedars-Sinai researchers have identified a biological repair process ...

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 ...

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

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 ...

A new study shows, for the first time, how the human genome folds and moves in 3D over time to control when genes turn on and ...

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 ...

In recent years, the field of immunology has increasingly focused on the role of glycolipids and sphingolipids in the differentiation and function of innate immune cells, such as macrophages, ...

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 ...
