(5R)-5-Hydroxytriptolide (LLDT-8), a triptolide derivative with low toxicity, was previously reported to have strong immunosuppressive effects both in vitro and in vivo, but it remains unknown whether LLDT-8 has a therapy effect on systemic lupus erythematosus. In this study, we aimed to investigate the therapeutic effects of LLDT-8 on lupus nephritis in MRL/lpr mice, a model of systemic lupus erythematosus. Compared with vehicle group, different clinical parameters were improved upon LLDT-8 treatment: prolonged life-span of mice, decreased proteinuria, downregulated blood urea nitrogen and serum creatinine, reduced glomerular IgG deposits, and ameliorated histopathology...

Similar to patients with other rheumatic diseases, patients with systemic lupus erythematosus (SLE) nowadays can also have the desire to terminate immunosuppressive and immunomodulatory medications. In order to provide appropriate advice to patients, the two main issues are the risk of severe adverse events under long-term therapy with any drug and the perceived risk of a flare, in particular of severe flares. The risks of long-term therapy vary greatly between drugs, ranging from severe unacceptable risks with cyclophosphamide and higher dose glucocorticoids to low risks usually outweighed by long-term benefits with hydroxychloroquine...

OBJECTIVE: Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by extensive immune response including over-activation of T and B cells development of pathogenic autoantibodies, organ damage induced by the formation and deposition of immune complex, and the abnormal elevation of type I interferon. Semaphorin5A (Sema5A), is essentially involved in immune cell regulation and also implicated in the pathogenesis of autoimmune disorders. We aimed to evaluate the role of Sema5A in patients with SLE...

Lupus nephritis is a frequent complication and a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Area covered: The main characteristics and mechanisms of action of the synthetic drugs more frequently used in lupus nephritis are described. Possible strategies aimed to reduce the potential adverse events without affecting efficacy are reported. Expert opinion: Many synthetic immunosuppressive drugs used in lupus nephritis have a low therapeutic index. Good knowledge of their pharmacologic characteristics, mechanisms of action, and drug-to-drug interactions, coupled with a strategy aimed to increase immunosuppression in the active phases of SLE while reducing the dosage in quiescent periods can reduce the iatrogenic morbidity while maintaining efficacy...

Systemic lupus erythematosus (SLE) is an autoimmune syndrome associated with severe organ damage resulting from the activation of immune cells. Recently, a role for caspase-1 in murine lupus was described, indicating an involvement of inflammasomes in the development of SLE. Among multiple inflammasomes identified, the NLRP3 inflammasome was connected to diverse diseases, including autoimmune encephalomyelitis. However, the function of NLRP3 in SLE development remains elusive. In this study, we explored the role of NLRP3 in the development of SLE using the pristane-induced experimental lupus model...

Renal involvement in systemic lupus erythematosus (SLE) is common and has been associated with an increased risk of mortality [1]. Early diagnosis is imperative to control proteinuria and prevent the progression to end-stage renal disease. Standard induction therapies include cyclophosphamide (CYC) and mycophenolate mofetil (MMF); however, it has been estimated that approximately 30% of patients are refractory to these standard treatments after 1 year [2]. We present two cases of patients diagnosed with lupus nephritis (LN) who demonstrated persistent proteinuria while on standard treatments that markedly improved after addition of thalidomide (THD)...

BACKGROUND: In lupus nephritis (LN), deposition of pathogenic autoantibodies in the glomeruli is mediated via cross-reactivity with alpha-actinin. Association of serum alpha-actinin antibody (AαA) with LN has been shown in a few studies but the results are controversial. METHODS: Eighty patients into entered the study. The diagnosis of SLE was confirmed according to the American College of Rheumatology criteria and LN was diagnosed by proteinuria ≥ 500 mg/24 hour and kidney biopsy...

OBJECTIVES: The targeting of negative checkpoint regulators (NCRs) as a means of augmenting anti-tumor immune responses is now an increasingly utilized and remarkably effective approach to the treatment of several human malignancies. The NCR VISTA (V-domain Ig suppressor of T cell activation, PD-1H, DD1α) suppresses T cell responses and regulates myeloid activities. We proposed that exploitation of the VISTA pathway is a novel strategy for the treatment of human autoimmune disease and therefore studied the impact of VISTA genetic deficiency on lupus development in a lupus-prone mouse strain...
