[Suppressive effect of Saibokuto on Dermatophagoides farinae (Df) antigen-induced IL2 responsiveness of lymphocytes from asthmatic children].

The effect of Saibokuto on induction of antigen specific IL2 responsiveness was studied. Saibokuto suppressed the induction of IL2 responsiveness induced by Dermatophagoides farinae (Df) antigen in peripheral blood mononuclear cells from patients with bronchial asthma. Saibokuto-pretreated adherent cells failed to present Df antigen to non-adherent responding T cells for induction of their IL2 responsiveness. The same dose of Saibokuto had no impact on non-adherent cells. Saibokuto also suppressed the induced IL2 responsiveness of lymphocytes from the same patients on stimulation wit PPD, but not with Con A. These combined data suggests that Saibokuto has a weak immunosuppressive effect on Df induced IL2 responsiveness of lymphocytes from asthmatic children.
