R. Vanree et Rc. Aalberse, DEMONSTRATION OF CARBOHYDRATE-SPECIFIC IMMUNOGLOBULIN G4 ANTIBODIES IN SERA OF PATIENTS RECEIVING GRASS-POLLEN IMMUNOTHERAPY, International archives of allergy and immunology, 106(2), 1995, pp. 146-148
From a group of 92 patients receiving grass pollen immunotherapy, and
selected on grounds of high IgG(4) titers against Lol p I, sera were t
ested for IgG(4) antibodies against the glycosylated grass pollen alle
rgen Lol p XI. In 72 of 92 cases IgG(4) antibodies were demonstrated.
The N-glycan of Lol p XI was earlier shown to be an epitope for IgE an
tibodies. In the present study it was demonstrated that the carbohydra
te structure is also recognized by IgG(4) antibodies, illustrating tha
t IgG(4) responses are not immune-restricted to peptide epitopes, as w
as suggested in several reports.
