Sublingual grass pollen immunotherapy is associated with increases in sublingual Foxp3‐expressing cells and elevated allergen‐specific immunoglobulin G4, immunoglobulin A and serum inhibitory activity for immunoglobulin E‐facilitated allergen binding to B cells

Abstract

SLIT with grass pollen extract is associated with increased Foxp3(+) cells in the sublingual epithelium and systemic humoral changes as observed previously for SCIT.
