Regulatory T Lymphocyte-Derived Extracellular Vesicles Play A Role in Chronic Kidney Diseases and Kidney Transplantation: A Review

Abstract

Chronic kidney disease (CKD) significantly affects kidney function, often leading to end-stage kidney disease (ESKD). Due to its high rates of morbidity, mortality, and economic effects, CKD is becoming the ninth most important risk factor for mortality worldwide, presenting serious healthcare issues. Regulatory T lymphocytes (Tregs) play a role in regulation, particularly in transplant tolerance and autoimmune conditions. Recent research has highlighted the potential of Tregderived vehicles (EVs) to modulate responses and promote graft tolerance during kidney transplantation. These EVs can suppress effector T lymphocytes (T effect), trigger apoptosis, and modify cytokine production to maintain balance and prevent graft rejection. Moreover, Treg-EVs have emerged as potential biomarkers for diagnosing CKD, paving the way for new diagnostic and therapeutic strategies. This study explores how Treg-derived EVs influence processes underlying CKD and kidney transplantation, highlighting their significance as useful tools.
