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 ...

Hormones coordinate different body functions by carrying messages through the bloodstream to target cells and tissues. Hormonal imbalances occur through inadequate or excess hormone synthesis, which ...

All cells need to sense and respond to their environment—to know when to activate genes, build proteins and carry out their basic functions. One of the most well-studied cellular responses is how they ...

Biomedical researchers at Texas A&M University may have discovered a way to stop or even reverse the decline of cellular energy production—a finding that could have revolutionary effects across ...

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 ...

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, ...

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cells in the human brain, according to the latest ...

Whether it’s counting red blood cells under a light microscope or recording bursts of electricity as neurons fire, scientists spend a lot of time studying cells. With such a diversity in form and ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
