antigen

 

[ หˆรฆntษชdส’ษ™n ]

Noun
Context #1 | Noun

biological term

An antigen is a substance that elicits an immune response in the body. It can be a pathogen, such as a virus or bacterium, or a foreign substance, like pollen or food. Antigens typically provoke the production of antibodies, which specifically target and neutralize them. Each antigen has distinct molecular characteristics that allow the immune system to recognize and remember them.

Synonyms

immunogen, marker

Examples of usage

  • The vaccine contains a harmless version of the antigen.
  • Exposure to the antigen triggered a strong immune response.
  • The lab tested for specific antigens related to the disease.

Etymology

The term 'antigen' originated in the early 20th century, derived from combining 'anti-' meaning 'against', and 'gen' from 'generator', referring to a substance that generates an immune response. The usage of the term became more widespread with the advancement of immunology as scientists began to understand how the immune system identifies and responds to foreign substances in the body. The concept of antigens helped to shape modern vaccine development, diagnostics, and therapeutic strategies in medicine. Over the decades, a more nuanced understanding of various types of antigens, including haptens and superantigens, has evolved, further informing both research and clinical practices.
