Ontogeny of the cells synthesizing IgE reaginic antibodies
IgE and IgD antibodies to ovalbumin were analyzed in animals immunized by three different techniques. The results showed that IgE and IgD immune responses could be induced more or less independently by different immunization schedules. Moreover, the triggering of the IgD membrane receptors of the IgE-B lymphoid cells which seems necessary to obtain a primary reaginic immune response, does not necessarily seem to induce an IgD immune response at the same time. We conclude IgE and IgD circulating antibodies are synthesized by two different B lymphoid cell lines.
