چکیده
Objective(s): Previously we reported functional leukocyte immunoglobulin-like receptor A3 (LILRA3) leads to susceptibility and sub-phenotypes of several autoimmune diseases. LILRA3 levels in blood serum and CD14+ monocytes enhanced in systemic lupus erythematosus and resulted in disease severity. However, the mechanism of LILRA3 in the pathogenesis of autoimmunity remains elusive. This study aims to explore the potential impact of LILRA3 on the differentiation, maturation, and function of monocyte-derived DCs (MoDCs).Materials and Methods: The human monocytic cell line (THP-1) was cultured to derive MoDCs in vitro. We performed plasmid transfection to examine the impact of LILRA3 on monocyte differentiation. Surface markers on MoDCs were measured using FACS. To assess the function of mature MoDCs, IL-12p70, IFN-γ and IL-4 levels were detected after the mixed leucocyte response by enzyme-linked immunosorbent assay. Western blot assay was employed in this study to determine the signaling pathways in MoDCs activation.Results: LILRA3 promotes MoDCs maturation, our results showed significant up-regulation of CD40, CD80, CD86, CD209, and HLA-DR and increased production of pro-inflammatory cytokine IL-12. LILRA3-treated MoDCs exhibited a robust proliferation of allogeneic CD4+ T cells and induced naïve CD4+ T cell polarization into the Th1 phenotype. Furthermore, the preceding activation of MoDCs maturation and LILRA3 function might be attributed to p38 MAPK and STAT1 signaling pathway’s aberrant activation. Conclusion: This is the first study to report that LILRA3 played a critical role in promoting MoDCs maturation and directing MoDCs to modulate Th1 cell differentiation, which may have a role in the pathogenesis of autoimmune diseases.کلیدواژه ها
