title: Pollen-allergen IgE response in the inbred rat. Regulation of allergen P-IgE antibodies in high and low responders by suppressive factors.
abstract: Cyclophosphamide treatment (100 mg/kg) significantly increased the IgE response to plane-tree allergen P in low-responder strains of rats. A suppressive serum was obtained by injection of CFA in normal low-responder strains. The injection of this serum 2 days after cyclophosphamide treatment and 1 day prior to primary immunization, reversed the cyclophosphamide-enhanced IgE antibodies response without affecting the IgG2a levels. This effect is strain specific.
