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

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 ...

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 ...

The 2020 Nobel Prize in Chemistry was awarded for the development of CRISPR/Cas9, a method also known as "gene scissors," which enables researchers to better understand how human cells function and ...

The cells in human bodies are subject to both chemical and mechanical forces. But until recently, scientists have not understood much about how to manipulate the mechanical side of that equation. That ...

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, ...

An international research team led jointly by the University Medical Center Göttingen (UMG), the University of Göttingen and the University of Western Ontario in London, Canada, has shown that nerve ...

I always wanted to understand life. What moves us? What allows us to heal and thrive? And what goes wrong when we get sick or when we eventually stop breathing and die? My search for answers to these ...

Crypt-base-columnar cells are continuously dividing intestinal stem cells that generate IECs, which are composed by distinct specialised cell types that play different functions: Enterocytes (in the ...

Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...

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