INTRODUCTION The TAM (tyro 3, axl, mer) kinases are key regulators of innate immunity and are important in the phagocytosis of apoptotic cells. Gas6 and protein S are ligands for these TAM kinases and bind to phosphatidyl serine residues exposed during apoptosis. In animal models, absence of TAM kinases is associated with lupus-like disease. To test whether human systemic lupus erythematosus (S...

fifty-seven patients suffering from systemic lupus erythematosus with different clinical features were studied from various aspects of immunological abnormalities, including anti-nuclear antibodies; anti-dna; anti-sm (smith's antigen); and, other extractable nuclear antigens. the tests employed were microhemagglutination, counter immunoelecterphoresis, and radio immunoassay (ria). the compariso...

Background: Systemic Lupus Erythematosus is a kind of multi-system autoimmune disorder with unknown aetiology and it produces antibodies against various tissues. Case Presentation:The patient wasa 44-year-old woman with a history of Systemic Lupus Erythematosus for approximately five years, along with underlying diseases including peptic ulcers, asthma, h...

objective(s):genetic and environmental factors are involved in the pathogenesis of systemic lupus erythematosus (sle). autoreactive lymphocytes are cleared through apoptosis and any disturbance in the apoptosis or clearance of apoptotic cells may disturb tolerance and lead to autoimmunity. vitamin d has anti-proliferative effects and controls cell cycle progression. in this study we investigate...

objective(s): lupus nephritis (ln) is the main cause of mortality and disability in systemic lupus erythematosus (sle) patients. therefore, utilizing a reliable and non-invasive method for serial measurements of renal function seems to be necessary. the aim of this study was to evaluate the role of urinary lipocalin-2 as a biomarker of renal involvement in sle patients.   materials and methods:...

Objective(s): lupus nephritis (LN) is a severe form of systemic lupus erythematosus (SLE) with renal complications. Current diagnosis is based on invasive renal biopsy and serum antibodies and complement levels that are not specific enough. The current study aims to identify new biomarker candidates for non-invasive diagnosis of LN and explore the pathogenic mechanisms...

background: systemic lupus erythematosus (sle) has various presentations in children. hematologic abnormalities is common in childhood onset of sle, however, isolated thrombocytopenia is relatively rare. thus, we present a child with isolated thrombocytopenia as a rare presentation of sle. case presentation: a 12-year-old boy with chief complaints of loss of appetite, weight loss, decreased pla...
