👉 Sensitisers are substances that can be activated in a specific way, causing an immediate or prolonged response. They are often used in medical settings to treat conditions such as allergic reactions and inflammation. For example, a sensitizer could be a substance that binds to certain proteins in the body, causing them to release chemicals that can trigger an immune response. These substances might include antibodies, which can bind to antigens on the surface of pathogens or cells, leading to an immediate or prolonged immune response.
