Overview of Cell Signaling Technology What is Cell Signaling?
Cell signaling is the highly complex communication process that controls simple cellular functions and regulates cellular actions by synchronizing the actions of the cells. It is the communication of molecular signals initiated from outside the cell towards its interior to cause a specific cellular response. For multicellular organisms, cell signaling must support homeostasis, development, and function.
Key Components of Cell Signaling
- Signaling Molecules: These include hormones, neurotransmitters, and growth factors for transmitting signals across cells.
- Receptors: Proteins either located on or inside the cell, which can bind to signaling molecules.
- Signal Transduction Pathways: A series of biochemical reactions that transfer the signal from the receptor to the target molecules.
- Cellular Response: The endpoint of the signaling process, perhaps changes in gene expression, cell division, or apoptosis.
Types of Cell Signaling Pathways
- Autocrine Signaling: Cells respond to signals they produce.
- Paracrine Signaling: Signals affect neighboring cells.
- Endocrine Signaling: The hormones move through the blood into distant cells, where they have an effect.
- Juxtacrine Signaling: A direct cell-to-cell contact must be made for signal transmission.
