signalöverföringshändelser
Signalöverföringshändelser refers to the processes by which cells communicate with each other. This communication is essential for all multicellular organisms, enabling them to coordinate a vast array of functions, from simple muscle contractions to complex thought processes. The fundamental principle involves a signaling molecule, often called a ligand, released by a signaling cell. This ligand then travels to a target cell and binds to a specific receptor protein on its surface or within its interior.
The binding of the ligand to the receptor triggers a cascade of intracellular events within the target
There are several major types of signalöverföringshändelser. Endocrine signaling involves hormones that travel through the bloodstream
