Antigen Notes:
The term antigen refers to any molecule or a linear molecular fragment after processing the native antigen that can be recognized by T-cell receptor. Antigens are "targeted" by antibodies. Each antibody is specifically produced by the immune system to match an antigen after cells in the immune system come into contact with it and this allows a precise identification or matching of the antigen and the initiation of a tailored response.
