Meaning and Definition
A molecule on cell surfaces that can provoke an immune response when tissue is transplanted from one individual to another, potentially causing rejection.
In immunology, these antigens are central to histocompatibility, used to match donors and recipients in organ and tissue transplants to minimize rejection risks; often synonymous with histocompatibility antigens like HLAs.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage; minor pronunciation variations exist.
Connotations
Identical in both dialects, with a technical, medical focus.

Mnemonic
Think: 'Transplant' + 'antigen' = the antigen that matters in transplants, like a name tag for cells.
Conceptual Metaphor
Often described as a 'lock and key' system where antigens are keys that immune cells check to identify foreign tissue.
