Induction of tolerance after establishment of peanut allergy by the food allergy herbal formula‐2 is associated with up‐regulation of interferon‐γ

Abstract

FAHF-2 treatment established PN tolerance in this model, which persisted for at least 4-week post-treatment. This result was associated with modulation of intestinal T helper type 1 cell (Th1) and Th2 cytokine production, and with increased numbers of mesenteric IFN-gamma-producing CD8+ cells.
