Expression of Transforming Growth Factor β1 in Patients With and Without Previous Abdominal Surgery

Effect of IgA Aggregates on Transforming Growth Factor-β1 Production in Human Mesangial Cells and the Intraglomerular Expression of Transforming Growth Factor-β1 in Patients with IgA Nephropathy

BACKGROUND Transforming growth factor-beta (TGF-beta) stimulates renal fibrosis in various renal diseases including IgA nephropathy. METHODS We examined whether immunoglobulin A (IgA) stimulated TGF-beta1 synthesis in human mesangial cells (MCs), and whether this effect was mediated through the protein kinase C (PKC) pathway. We measured the intraglomerular TGF-beta1 mRNA expression by using ...

Human Leukocyte Antigen-G Expression on Dendritic Cells Induced by Transforming Growth Factor-β1 and CD4+ T Cells Proliferation

Background: During antigen capture and processing, mature dendritic cells (DC) express large amounts of peptide-MHC complexes and accessory molecules on their surface. DC are antigen-presenting cells that have an important role in tolerance and autoimmunity. The transforming growth factor-beta1 (TGF-β1) cytokine has a regulatory role on the immune and non-immune cells. The aim of this study is ...

Transforming growth factor-β1 and diabetic nephropathy.

Transforming growth factor-β1 (TGF-β1) is established to be involved in the pathogenesis of diabetic nephropathy. The diabetic milieu enhances oxidative stress and induces the expression of TGF-β1. TGF-β1 promotes cell hypertrophy and extracellular matrix accumulation in the mesangium, which decreases glomerular filtration rate and leads to chronic renal failure. Recently, TGF-β1 has been demon...

Transforming growth factor-β1 in plaque morphea

INTRODUCTION Morphea (localized scleroderma) is a rare cutaneous disease characterized by skin fibrosis of unknown pathogenesis. Transforming growth factor-β (TGF-β) is a potent profibrotic factor. The role of TGF-β in morphea remains unclear. AIM The goal of this study was to estimate the expression level of TGF-β1 in skin and peripheral blood mononuclear cells as well as the plasma levels o...
