Adaptive immune responses arise as a result of exposure to foreign comp. The compound that evokes the response is referred to as Antigens.

An antigen is any agent capable of binding specifically to T-cell receptor or an antibody molecule.

The ability of a compound to bind with an antibody or a TCR is referred to as Antigenicity.
