Monocytes are an important component in the innate immune system. However, studies to date have failed to conclude whether their levels are altered in patients with systemic lupus erythematosus (SLE). We applied the cytodiff counting method and comprehensively measured the circulating levels of distinct white blood cell (WBC) subsets, including CD16+, CD16-, and total monocytes, in 61 SLE patients as well as in 203 age-matched healthy controls (HCs). The absolute number of CD16- monocytes, total monocytes, immature granulocytes, mature neutrophils, total neutrophils, and T cell blasts was significantly higher, that of non-cytotoxic T lymphocytes, cytotoxic T + NK lymphocytes, T + NK lymphocytes, total lymphocytes, basophils, and eosinophils significantly lower (all p < 0...

INTRODUCTION: End-stage renal disease (ESRD) due to lupus nephritis (LN) occurs in 10%-30% of patients. Initially systemic lupus erythematosus (SLE) was a contraindication for kidney transplantation (KT). Today, long-term graft survival remains controversial. Our objective was to compare the survival after KT in patients with SLE or other causes of ESRD. METHODS: All SLE patients who had undergone KT in a retrospective cohort were included. Renal graft survival was compared with that of 50 controls, matched for age, sex, and year of transplantation...

Immunoreceptors can transduce either inhibitory or activatory signals depending on ligand avidity and phosphorylation status, which is modulated by the protein kinases Lyn and Fyn. Here we show that Lyn and Fyn control immune receptor signaling status. SHP-1 tyrosine 536 phosphorylation by Lyn activates the phosphatase promoting inhibitory signaling through the immunoreceptor. By contrast, Fyn-dependent phosphorylation of SHP-1 serine 591 inactivates the phosphatase, enabling activatory immunoreceptor signaling...

OBJECTIVES: The presence of tubulointerstitial damage (TID) on renal biopsy is considered to be a late sequela of lupus nephritis (LN). The objective of this study was to determine if TID predicts progression to end stage renal disease (ESRD) in LN patients without advanced kidney disease. METHODS: All SLE patients with an index biopsy consistent with LN between January 2005 and July 2015, and eGFR ≥ 30mL/min/1.73m(2) were included. Moderate-to-severe TID was defined as the presence of moderate-to-severe tubular atrophy and/or interstitial fibrosis...

Lupus nephritis (LN), one of the most severe outcomes of systemic lupus erythematosus (SLE), is initiated by glomerular deposition of immune-complexes leading to an inflammatory response and kidney failure. Autoantibodies to nuclear antigens and autoreactive B and T cells are central in SLE pathogenesis. Immune mechanisms amplifying this autoantibody production drive flares of the disease. We previously showed that basophils were contributing to LN development in a spontaneous lupus-like mouse model (constitutive Lyn (-/-) mice) and in SLE subjects through their activation and migration to secondary lymphoid organs (SLOs) where they amplify autoantibody production...

Background Childhood-onset systemic lupus erythematosus (cSLE) is a lifelong autoimmune disorder. The vitamin D receptor (VDR) gene is a potential candidate gene for cSLE susceptibility. In this study, we aimed to investigate the FokI polymorphism in the VDR gene in Egyptian children and adolescents with SLE, to determine whether this polymorphism could be a genetic marker for cSLE susceptibility or disease activity and we also measured the serum level of 25-hydroxyvitamin D [25(OH) D] to assess its relation to such polymorphism...

Complement activation is associated with common rheumatic diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and systemic vasculitis. Evidence linking complement activation to these diseases includes the presence of complement deposition in affected tissues, decreased levels of complement proteins and high levels of complement activation fragments in the blood and/or synovial fluid of patients with these diseases, as well as data from experimental models. Eculizumab, a monoclonal antibody that inhibits the complement component C5, is now approved for the treatment of rare conditions involving complement hyperactivation, and the success of this therapy has renewed interest in understanding the utility of complement inhibition in rheumatological practice, particularly for SLE...

Lupus nephritis (LN) is a common complication of systemic lupus erythematosus. The present study aimed to elucidate the protective effect of magnolol (MG) on the progression of LN, via inhibition of key signaling pathways. The results of the present study demonstrated that administration of MG caused inhibition of the activation of NACHT, LRR and PYD domains‑containing protein 3 and interleukin‑1β production. Histopathological analysis confirmed that the vehicle‑treated group exhibited characteristic glomerular disease, which was observed to be suppressed following the administration of MG; a marked decrease in glomerular and vascular lesions was observed compared with the vehicle control...

As demonstrated by Alport syndrome, the co‑occurrence of auditory and urinary system malformations, and gentamicin-induced ototoxicity and nephrotoxicity, the ears and kidneys potentially share certain molecular pathways. In the present study, microarray chips were used to analyze the changes in the gene expression profile using a rat model of gentamicin‑induced ototoxicity and nephrotoxicity, using rat liver tissue as a control. A number of genes were identified to exhibit similar expression changes in the rat ears and kidney tissues, among which microtubule‑associated protein 44 (Ifi44), was selected for further analysis to validate its expression changes and confirm potential involvement in the inflammation process in the disease model...

CD4(+) T cells are important drivers of tissue damage in immune-mediated renal diseases, such as anti-glomerular basement membrane glomerulonephritis, anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, and lupus nephritis. The discovery of a distinct, IL-17-producing CD4(+) T-cell lineage termed T helper type 17 (TH17) cells has markedly advanced current understanding of the pathogenic mechanisms of organ-specific immunity and the pathways that lead to target organ damage. TH17 cells are characterized by the expression of the transcription factor RORγt, the production of the pro-inflammatory cytokines IL-17A, IL-17F, IL-22, and high expression of the chemokine receptor C-C-motif chemokine receptor 6 (CCR6)...

BACKGROUND: In clinical trials, the addition of rituximab (RTX) to the combination therapeutic regimen of mycophenolate mofetil (MMF) and corticosteroids failed to improve outcome in lupus nephritis (LN). However, recent data suggest that RTX may have steroid-sparing beneficial effects with an efficacy similar to that of conventional regimens. We report our experience with RTX in the treatment of children with LN. METHODS: Patients treated with RTX for first occurrence of LN class III to V were enrolled in the study...
