Presence of Immunoglobulin‐containing Plasma Cells in Tonsils From Tonsillectomized Children

Immunofluorescence investigations of IgG, IgA, IgM and IgE plasma cells in tonsil biopsies from 52 children, most of whom were suffering from chronic tonsillitis and frequent acute exacerbations of tonsillitis, are presented. The most prominent finding was a lack of IgE fluorescing plasma cells in 60 per cent of patients. IgA plasma cells were absent in 30 per cent of the patients and in 25 per cent IgA as well as IgE plasma cells were absent.;
