Measurement of the soluble fms-like tyrosine kinase 1 (sFlt-1)/placental growth factor (PlGF) ratio may be clinically useful to discriminate systemic lupus erythematosus (SLE) from preeclampsia. Here, we present a pregnant woman with new-onset SLE with hypertension, with the measurement of the
BACKGROUND
The tertiary structure of normal podocytes prevents protein from leaking into urine. Patients with lupus nephritis (LN) develop proteinuria, and kidney biopsies from these patients display a number of podocyte abnormalities including retraction of podocyte processes. Autoantibodies have
Systemic lupus erythematosus (SLE) is an autoimmune disease manifested by multiorgan impairment. It is reported that B cells participate in the onset of SLE. Bruton's tyrosine kinase (Btk), as a downstream signaling molecule of B cell antigen receptor (BCR) signaling pathway, is involved in the
Mer and Axl receptor tyrosine kinases (MerTK and AxlTK) play important roles in the clearance of apoptotic cells and the inhibition of inflammatory responses. Previous studies demonstrated that they might participate in glomerular injury in mice model. This study aimed to elucidate the expression of
The Fc receptors (FcR) have pivotal roles in the pathogenesis of the autoimmune glomerulonephritis. We therefore investigated the effects of a Syk inhibitor on the progression of lupus nephritis and SH3 domain binding protein 2 and p38MAP kinase signalings in mice. NZB/W F1 mice, a model of lupus
Objectives: Growth arrest-specific 6 (Gas6) and its receptors have been shown to play a crucial role in the homeostasis of the innate immune system by regulating apoptosis and inflammation. We aimed to verify whether an impairment of this
OBJECTIVE
To assess whether R788, an orally bioavailable small molecule inhibitor of spleen tyrosine kinase (Syk)-dependent signaling, could modulate disease in lupus-prone (NZB x NZW)F1 (NZB/NZW) mice via inhibition of Fc receptor (FcR) and B cell receptor signaling.
METHODS
R788 was administered
Lupus nephritis (LN) is a potentially dangerous end organ pathology that affects upwards of 60% of lupus patients. Bruton's tyrosine kinase (BTK) is important for B cell development, Fc receptor signaling, and macrophage polarization. In this study, we investigated the effects of a novel, highly
This study analysed the expression and activation of proline-rich tyrosine kinase 2 (PYK2) in peripheral blood mononuclear cells (PBMCs) from 36 systemic lupus erythematosus (SLE) patients and explored whether activation of PYK2 correlates with disease activity or organ damage in SLE. Samples from
The Src homology and collagen A (ShcA) adaptor protein that binds to tyrosine kinase receptors. ShcA plays a role in insulin signaling, stress resistance and energy metabolism. The 66-kDa Src homology 2 domain-containing protein (p66shc) belongs to the ShcA family and has been associated with
OBJECTIVE
The aim of the present study was to investigate plasma concentrations of Gas6 and its soluble tyrosine kinase receptor sAxl in Systemic lupus erythematosus (SLE) and Behçets disease (BD) patients and to correlate those levels with clinical and laboratory manifestations of the
Soluble fms-like tyrosine kinase 1 (sFLT1) is a splice variant of the vascular endothelial growth factor (VEGF) receptor lacking the transmembrane and cytoplasmic domains and acts as a powerful antagonist of VEGF signaling. Plasma sFLT1 levels are higher in patients with chronic kidney BACKGROUND
Mer and Tyro3 are receptor tyrosine kinases important for the phagocytosis of apoptotic cells. Together with Axl, they constitute the TAM receptor family. These receptors can be shed from the cell membrane and their soluble extracellular regions can be found in plasma. The objective of
Pre-eclampsia (PE) is a major cause of maternal mortality and morbidity, perinatal deaths, preterm birth and intrauterine growth restriction. Differential diagnosis with antiphospholipid syndrome (APS) nephropathy and systemic lupus erythematosus (SLE) nephritis during pregnancy is difficult, if not
Glomerulonephritis is one of the most severe manifestations of systemic lupus erythematosus, with considerable morbidity and mortality. There remains a major unmet need for successful management of lupus nephritis. TAM family receptor tyrosine kinases (Mer and Axl) play an important role in the
