Sejtszignálásban, often translated as cell signaling, is the fundamental process by which cells communicate with each other and with their environment. This communication is essential for coordinating complex biological functions within multicellular organisms, as well as for individual cells to respond to external stimuli. Signaling typically involves a signaling molecule, a receptor, and intracellular signaling pathways.
Signaling molecules, also known as ligands, can be hormones, neurotransmitters, growth factors, or even physical contact
These pathways often involve a series of protein phosphorylations or other modifications that amplify the initial
