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 ...

A 3D rendering showing the internal structure of an animal cell, with several round or wavy structures inside a border. It turns out that the redox state of a cell, such as the animal cell shown, is ...

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 ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

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 ...

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