JAK/STAT signaling pathway

The JAK/STAT signaling pathway is a way cells communicate to respond to signals like hormones and immune messengers. When these signals bind to specific receptors on a cell's surface, they activate enzymes called JAKs. JAKs then add a phosphate group to STAT proteins, which step into the nucleus and turn on genes that control cell behavior, growth, and immune responses. This pathway helps the body regulate processes like immunity, development, and blood cell production, ensuring that cells respond appropriately to their environment.
