Glucocorticoid hormones have been widely used in clinical practice as potent anti-inflammatory and immunosuppressive agents. However, the underlying mechanisms of how they work remain unaddressed. Here, we used RNA-set to profile spleen gene expression in adult mice after consistent intraperitoneal injection of dexamethasone. We identified 13565 genes in control (injected with 0.9% NaCl) and 13702 genes in dexamethasone-injected group, 12920 genes were expressed in both, but 645 genes were identified only in control and 782 genes were identified only in the dexamethasone group...

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease that can involve nervous system commitment known as neuropsychiatric systemic lupus erythematosus (NPSLE). The diagnostic of NPSLE is complex because the symptoms range from focal symptoms (e.g., strokes, thrombotic events) to diffuse disorders affecting cognition, mood and level of consciousness (e.g. acute confusional state, psychosis). Both type of manifestations of NPSLE differ in their pathological mechanisms. The focus of this review will be on the mechanisms that lead to the blood-brain barrier (BBB) disruption and to the neuroinflammation related with the diffuse manifestations of NPSLE...

Background Direct oral anticoagulants (DOACs) cause false positive lupus anticoagulant (LA) results. We assessed the impact of DOAC-Stop, reversing in vitro effects of DOACs, on LA testing in anticoagulated patients. Methods We assessed 75 venous thromboembolism patients aged 44.5±14.6 years. Blood samples were collected 2-28 h since intake of DOACs, including 50 patients on rivaroxaban, 20 on dabigatran and five on apixaban. LA testing was performed at baseline and after DOAC-Stop treatment. Positive LA was defined as the normalized (patient/standard plasma clotting time) LA screening and screening (LA1)/confirmation (LA2) ratios exceeding 1...

Checkpoint blockade immunotherapy has revolutionized the treatment of advanced melanoma, with impressive survival benefits attained through upregulation of the anticancer immune response. Blockade of regulatory checkpoint molecules can, however, also result in aberrant immune activation leading to undesirable inflammation and autoimmunity. Although many genetic determinants have been described in patients with primary autoimmune diseases, it is uncertain whether patients developing autoimmune skin disease as an adverse effect of anti-PD-1 therapy share the same genetic risks...

The complement component C3 is at the heart of the complement cascade. It is a complex protein, which generates different functional activated fragments (C3a, C3b, iC3b, C3c, C3d). C3b is a constituent of the alternative pathway C3 convertase (C3bBb), binds multiple regulators, and receptors, affecting thus the functioning of the immune system. The activated forms of C3 are a target for autoantibodies. This review focuses on the discovery, disease relevance, and functional consequences of the anti-C3b autoantibodies...

Baicalin is a natural compound isolated from Chinese herb, which has been reported as an anti-inflammatory drug. Here, we demonstrated that Baicalin treatment could reduce urine protein, inhibit anti-ds-DNA antibody titers, and ameliorate lupus nephritis in MRL/lpr lupus-prone mice. Baicalin inhibited Tfh cell differentiation and IL-21 production, but promoted Foxp3+ regulatory T cell differentiation including part of follicular regulatory T (Tfr) cells. Intravenous injection of Baicalin-induced Foxp3+ regulatory T cells could relieve nephritis, inhibit Tfh cell differentiation and IL-21 production...

BACKGROUND: Antibodies to M-type phospholipase A2 receptor (a-PLA2 R) have been identified in most patients with idiopathic membranous nephropathy, but the prevalence in membranous lupus nephritis (MLN) is still unclear. The objective of this study was to assess the prevalence of a-PLA2 R antibodies in a large cohort of patients with lupus nephritis. METHODS: a-PLA2 R antibodies were measured by ELISA in serum from patients with systemic lupus erythematosus ( n = 190), of whom 37 had a biopsy-proven MLN...

BACKGROUND: Accumulating evidence suggests that the AKT/mTOR pathway plays an important role in the pathogenesis of systemic lupus erythematosus (SLE) through activating T cells, and there are few studies looking into the role of microRNA (miRNAs) in the mechanism. We first found that miR-633 expression in CD4+ T cells of SLE patients was significantly reduced. OBJECTIVE: To investigate the role of miR-633 in the AKT/mTOR pathway in lupus CD4+ T cells. METHODS: Samples of 17 SLE cases and 16 healthy controls were collected to detect the expression of miR-633, AKT1, mTOR mRNA and proteins by quantitative polymerase chain reaction (qPCR) and Western-blot, respectively...

Systemic lupus erythematosus (SLE) is an autoimmune disease that has high morbidity and can result in multi-organ damage. SLE is characterized by dysregulated activation of T- and B-lymphocytes and the production of autoantibodies directed against nuclear components. The endonuclease deoxyribonuclease 1 (DNase1) is abundant in blood and a subset of SLE patients have mutations in DNASE1. Furthermore, a report showed that Dnase1-deficient mice develop an SLE-like disease, but these mice also carry a deletion of the gene adjacent to Dnase1, which encodes the chaperone TRAP1/HSP75...

BACKGROUND: Lupus nephritis (LN) is a major risk factor for overall morbidity and mortality in systemic lupus erythematosus (SLE). METHODS: We retrospectively analyzed cases of proliferative and membranous LN patients who underwent a renal biopsy at our hospital in 1993-2016. We analyzed the association between complete renal response (CR) rates at 12 months after induction therapy and predictive factors for CR and their association with renal flares. RESULTS: Of the 95 cases analyzed, we were able to track the therapeutic responses of 81 patients at 12 months after their induction therapy...
