Activation of the classical pathway of human complement by monoclonal IgE from patient DES was demonstrated by using IgE(DES) coupled to latex particles. This material depleted human serum of C1 and C4 hemolytic activities. In addition, C3bi was deposited in a calcium-dependent way onto the insolubilized IgE as shown by the agglutination of latex by conglutinin. The alternative pathway was also activated. These anticomplementary activities were dose and time dependent. Moreover, we confirmed that another monoclonal IgE, IgE(PS), activated the alternative pathway exclusively. Particular attention was paid to exclude contamination by other immunoglobulins or C-reactive protein, generation of artifacts due to the chemical coupling, and the presence of proteolytic enzymes in the IgE(DES) preparation. Moreover, evidence is also presented against the involvement of IgG or IgM anti-IgE autoantibodies that could activate the classical pathway after their binding to insolubilized IgE(DES). Although one cannot exclude the possibility that IgE(DES) or IgE(PS) are abnormal proteins, these findings suggest the existence of an isotypic or allotypic variation of IgE.
