Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and ...

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...

RNA is usually portrayed as a molecule that works deep inside the cell, helping to turn genetic information into proteins.

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a form of inflammatory programmed cell death called necroptosis. Their ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before ...

A hidden “jack-in-the-box” mechanism inside T cells may hold the key to unlocking more powerful cancer immunotherapies.

Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism ...

One of the most exciting advances in cancer treatments in the past decade is the development of T cell immunotherapies, in which a patient's own immune system is trained to recognize and attack ...
