Regulation of myeloperoxidase‐specific T cell responses during disease remission in antineutrophil cytoplasmic antibody–associated vasculitis: The role of Treg cells and tryptophan degradation

Abstract

Our findings indicate that MPO-specific T cell frequencies are regulated during disease remission in association with tryptophan degradation. The tryptophan regulatory pathway is induced during active disease and persists during disease remission.
