One is the “antigen-template” theory, developed by Breinl, Haurowitz, Mudd, Alexander, and Pauling. This theory assumes that antibodies can be produced only by cells in which the antigen is present.

Observations suggesting the existence of natural antibody prior to exposure of an organism to the corresponding antigen, led to the natural selection theory of antibody formation of Jerne in 1955, and to the two signal hypothesis of Forsdyke in 1968.
