Dysregulation of the PD-1/PD-L1 pathway contributes to the pathogenesis of celiac disease

摘要

In this study,we focus on the alteration of the programmed cell death 1(PD-1)/PD-L1 pathway in celiac disease.We discuss the diverse roles of the PD-1 pathway in regulating immune responses and how this knowledge can improve celiac disease(CD)autoimmunity.The PD-1 and PD-L1 levels in the serum and in intestinal biopsies of CD patients may be relevant to the determination of a possible correlation between markers of the autoimmune response,inflammation,and disease activity.
