Summary A hypothesis if formulated for the mode of action of the ‘atopy gene’: the gene(s) causing an increased tendency to mount an IgE immune response to trivial environmental antigens. It is postulated that some antigens are not efficiently transported to the lymphoid organs, the location of the ‘eutopic’ immune system; migratory lymphoid cells may occasionally react and start an inefficient immune response in sites not so destined. This is called an ectopic immune response. This response lacks the regulatory influences prevailing in the lymphoid organs, which results in approximately equal quantities of the various immunoglobulin isotypes, including IgE. The atopy gene(s) work by increasing the risk of such an ectopic immune response.
