For decades, scientists have accepted that the immune system naturally weakens with age. Georgia Tech biomedical engineer and ...

Understanding how heart muscle cells stop dividing and acquire the characteristics needed to sustain lifelong cardiac ...

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 scientific review highlights how PIWI proteins and piRNAs regulate stem cell function, offering new epigenetic targets to ...

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

In many animal tissues, stem cells continually divide to create new cells that replace old or damaged ones. However, this ...

All cells metabolize nutrients to generate the energy and molecular building blocks required for survival. Cancer cells, ...

St. Jude Children's Research Hospital scientists have discovered how tumors disable immune "gatekeeper" cells that alert the rest of the immune system to the presence of cancer - and how restoring ...

Most cancer deaths are caused not by the initial tumor but by the spread of cancer cells to distant organs in the process ...

B lymphocytes exhibit dual roles in tumorigenesis, acting as both allies and adversaries in the tumor microenvironment (TME). Their anti-tumor functions include recognizing tumor-associated antigens, ...

A new study published in Science identifies a specialised dendritic cell subset as the cellular architects behind tertiary ...
