antigenic
Học thuậtThân thiện
Definition
Adjective: - Relating to or having the properties of an antigen: Describes something that is of, pertaining to, or involving an antigen—a substance that triggers the immune system to produce antibodies.
Usage
- The term "antigenic" is used primarily in immunology, medicine, and biology to describe the characteristics or behavior of antigens.
- It is often used to discuss how a substance (like a virus, bacterium, or vaccine component) interacts with the immune system.
Examples
- Adjective:
- The virus has a highly antigenic surface protein that is the target for most vaccines.
- Scientists study the antigenic drift of influenza viruses to update the annual flu vaccine.
- The antigenic properties of the new drug candidate were tested in the lab.
Advanced Usage
- "Antigenic shift": A major, abrupt change in the antigens of a virus, often leading to a new strain that can cause pandemics.
- The 2009 H1N1 pandemic was caused by an antigenic shift in the influenza virus.
- "Antigenic determinant" (or epitope): The specific part of an antigen molecule to which an antibody attaches.
- The antibody binds to a specific antigenic determinant on the pathogen's surface.
Variants and Related Words
- Antigen (n): A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
- Pollen can act as an antigen for people with allergies.
- Antigenicity (n): The capacity of a substance to act as an antigen; its ability to induce an immune response.
- The antigenicity of the vaccine component was confirmed through clinical trials.
Synonyms
- Immunogenic: Capable of inducing an immune response. (Note: While closely related, "immunogenic" often implies the successful of immunity, whereas "antigenic" describes the property of being recognized as an antigen.)
- The adjuvant was added to increase the immunogenic response to the vaccine.
Adjective
- of or relating to antigens
