WebbAbstract. 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. Aspects of these were not only first discoveries but also foundational discoveries in WebbP. describes a theory which he has compounded on the structure and process of formation of antibodies and the nature of serological reactions. He shows that many of the reported experimental results are compatible with the theory which, in the main, is based on the assumption that antibodies differ from normal serum globulin only in the way in which …

WebbThe theory states that in a pre-existing group of lymphocytes (specifically B cells), a specific antigen activates (i.e. selects) only its counter-specific cell, which then induces that particular cell to multiply, producing identical clones for antibody production. WebbNewly synthesized immunoglobulin molecules have different properties based upon their immunoglobulin class or isotype. Nevertheless, antigen-binding specificities reside in the Fab regions of antibody molecules, which governs their interactions with antigens in vitro and in vivo. By contrast, complement binding and activation capabilities ...
