NFAT (Nuclear Factor of Activated T-cells)

NFAT (Nuclear Factor of Activated T-cells) is a protein that plays a key role in the immune system. It acts as a messenger inside T-cells, which are immune cells that help defend the body against pathogens. When a T-cell is activated by an infection, signals trigger NFAT to move from the cell's cytoplasm into the nucleus (its control center). Once inside, NFAT helps turn on genes that produce important immune responses, such as releasing signaling molecules. This process is essential for proper immune function and helps the body respond effectively to threats.
