During the past 100 years, the major causes of death have shifted from INFECTIOUS DISEASES to CHRONIC DISEASES.
About a century ago, most diseases were usually acquired by people as a result of infection, that is, the causative organisms are usually passed from one person to another. But since the advent of microbiology in medicine, the trend has change, because the microbes can now be countered using different antibiotic means.
In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.
