The word antigen comes from "antibody generator" [1]. Any molecule that causes an immune response by binding with an antibody or T-cell receptor is an antigen, for this reason they are important in immunisation as they can induce a highly specific adaptive immune response. This occurs because of the activation of the innate immune response which uses Antigen presenting cells (APCs) to activate T-cells [2].
