Systemic lupus erythematosus (SLE) is a disease characterized by the production of a large number of autoantibodies. Defected phagocytosis of macrophage plays an important role in innate immunity in the pathogenesis of SLE. Tyro3 is a receptor responsible for the recognition of apoptotic cells during efferocytosis by macrophages. To investigate the role of Tyro3 receptor in macrophages\u2019 efferocytosis of apoptotic cells in SLE, we aimed to reveal the clinical relevance and impact of Tyro3 autoantibody on SLE.\n                    <jats:italic>Methods<\/jats:italic>\n                    . The serum levels of IgG\u2010type autoantibody against Tyro3 receptor were detected in new\u2010onset, treatment\u2010na\u00efve SLE patients (\n                    <jats:italic>n<\/jats:italic>\n                    = 70), rheumatoid arthritis (RA) (\n                    <jats:italic>n<\/jats:italic>\n                    = 24), primary Sj\u00f6gren\u2019s Syndrome (pSS) (\n                    <jats:italic>n<\/jats:italic>\n                    = 21), and healthy controls (HCs) (\n                    <jats:italic>n<\/jats:italic>\n                    = 70) using enzyme\u2010linked immunosorbent assay (ELISA). The effects of purified Tyro3 autoantibody from SLE patients on the efferocytosis of human monocyte\u2010derived macrophages were measured by flow cytometry and immunofluorescence.\n                    <jats:italic>Results<\/jats:italic>\n                    . The serum levels of IgG\u2010type autoantibody against Tyro3 receptor were significantly elevated in patients with SLE compared to RA, pSS, and HCs (all\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.0001). The levels of anti\u2010Tyro3 IgG were positively associated with the SLE disease activity index (SLEDAI) score (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.254,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.034), erythrocyte sedimentation rate (ESR) (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.430,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.001), C\u2010reactive protein (CRP) (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.246,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.049), and immunoglobulin G (IgG) (\n                    <jats:italic>r<\/jats:italic>\n                    = 0.408,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.001) and negatively associated with haemoglobin (Hb) (\n                    <jats:italic>r<\/jats:italic>\n                    = \u22120.294,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.014). ROC curves illustrated that the anti\u2010Tyro3 antibody could differentiate patients with SLE from HCs. Furthermore, flow cytometry and immunofluorescence demonstrated that purified anti\u2010Tyro3 IgG inhibited the efferocytosis of macrophages (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.004 and 0.044, respectively) compared with unconjugated human IgG.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    . These observations indicated that autoantibody against Tyro3 was associated with disease activity and could impair efferocytosis of macrophages.
