Persistent regulatory T‐cell response 2 years after 3 years of grass tablet <scp>SLIT</scp>: Links to reduced eosinophil counts, <scp>sIgE</scp> levels, and clinical benefit

Abstract

Our results suggest that the immunological mechanisms underlying the sustained response after 2 years of cessation of immunotherapy (3-year treatment period) are linked to the acquisition and maintenance of a regulatory T-cell response.
