Overview of Cell Signaling

Anuradha Chaudhary

Abstract


Cells regularly convey utilizing chemical signals. These chemical signs, which are proteins or different molecules produced by a sending cell, are regularly discharged • Sending cell: this cell secretes a ligand
• Target cell: this cell has a receptor that can tie the ligand. The ligand ties to the receptor and triggers a signaling cascade inside the cell, prompting to a response.
• Non target cell: this cell does not have a receptor for the ligand (however it might have different sorts of receptors). The cell does not see the ligand and in this manner does not react to it.

Not all cells can "hear" a specific chemical message. In order to detect a signal (that is, to be a target cell), a neighbor cell must have the correct receptor for that signal. At the point when a signaling molecule ties to its receptor, it adjusts the shape or movement of the receptor, triggering off a change within the cell. Signaling particles are regularly called ligands, a general term for molecules that predicament particularly to different molecules, (for example, receptors).
