Abstract
Regulatory T (Treg) cells are crucial for maintaining immune tolerance by suppressing response to self-antigens and harmless antigens to prevent autoimmune diseases and uncontrolled immune responses. Therefore, using Treg cells is considered a therapeutic strategy treating inflammatory diseases. Based on their origin, Treg cells are classified into thymus-derived, peripherally induced, and in vitro induced Treg cells. Our group discovered a novel Treg cell subset, namely, Treg-of-B (Treg/B) cells, generated by culturing CD4+CD25- T cells with B cells, including Peyer's patch B cells, splenic B cells and peritoneal B1a cells, for 3 days. Treg/B cells express CD44, OX40 (CD134), cytotoxic T-lymphocyte-associated antigen-4 (CD152), glucocorticoid-induced tumor necrosis factor receptor family-related protein (CD357), interleukin-10 receptor, lymphocyte activation gene-3 (CD223), inducible co-stimulator (CD278), programmed-death 1 (CD279), tumor necrosis factor receptor II, and high levels of IL-10, but not forkhead box protein P3, similar to type 1 Treg (Tr1) cells. However, unlike Tr1 cells, Treg/B cells do not express CD103, CD226, and latency-associated peptide. Treg/B cells have been applied for the treatment of some murine models of inflammatory diseases, including allergic asthma, inflammatory bowel disease, collagen-induced arthritis, gout, psoriasis and primary biliary cholangitis. This review summarizes the current knowledge of Treg/B cells.
期刊介绍:
Clinical Reviews in Allergy & Immunology is a scholarly journal that focuses on the advancement of clinical management in allergic and immunologic diseases. The journal publishes both scholarly reviews and experimental papers that address the current state of managing these diseases, placing new data into perspective. Each issue of the journal is dedicated to a specific theme of critical importance to allergists and immunologists, aiming to provide a comprehensive understanding of the subject matter for a wide readership.
The journal is particularly helpful in explaining how novel data impacts clinical management, along with advancements such as standardized protocols for allergy skin testing and challenge procedures, as well as improved understanding of cell biology. Ultimately, the journal aims to contribute to the improvement of care and management for patients with immune-mediated diseases.
