Increased expression of tumor necrosis factor-alpha converting enzyme and tumor necrosis factor-alpha in peripheral blood mononuclear cells in patients with advanced congestive heart failure.

BACKGROUND Tumor necrosis factor-alpha converting enzyme (TACE) has recently been identified as a metalloproteinase-disintegrin, which converts pro-tumor necrosis factor-alpha (TNF-alpha) to the mature form, and is an important mediator in the pathogenesis of CHF. AIMS In order to establish the importance of TACE in the regulation of TNF-alpha synthesis in peripheral blood mononuclear cells (...

Tumor necrosis factor α release in peripheral blood mononuclear cells of cutaneous lupus and dermatomyositis patients

INTRODUCTION Several studies have reported that TNFα is substantially increased within skin lesions of patients with discoid lupus erythematosus (DLE), subacute cutaneous lupus erythematosus (SCLE) and dermatomyositis (DM) compared to controls. Elevated TNFα has been reported in the sera of some patients with systemic lupus erythematosus, DLE and SCLE, but not in the sera of patients with DM. B...

Cardiotrophin-1 Induces Tumor Necrosis Factor α Synthesis in Human Peripheral Blood Mononuclear Cells

Chronic heart failure (CHF) is associated with elevated concentrations of tumor necrosis factor (TNF) alpha and cardiotrophin-1 (CT-1) and altered peripheral blood mononuclear cell (PBMC) function. Therefore, we tested whether CT-1 induces TNFalpha in PBMC of healthy volunteers. CT-1 induced in PBMC TNFalpha protein in the supernatant and TNFalpha mRNA in a concentration- and time-dependent man...

Tumor Necrosis Factor α from Peripheral Blood Mononuclear Cells of IgA Nephropathy and Mesangial Cell Proliferation

BACKGROUND To investigate the role of mononuclear cells and their products on rat mesangial cell proliferation, we evaluated the effect of peripheral blood mononuclear cells (PBMC) culture supernatant of patients with IgA nephropathy on rat mesangial cells 3[H]-thymidine uptake, and measured the concentration of cytokines in the supernatant to find out which cytokine in PBMC culture supernatant...

Increased gene expression of tumor necrosis factor superfamily ligands in peripheral blood mononuclear cells during chronic heart failure.

OBJECTIVE Inflammation may play a pathogenic role in chronic heart failure (CHF). The objective of the study was to characterise the imbalance in the cytokine network in CHF. METHODS cDNA expression arrays were used to analyse the gene expression of cytokines and related mediators in peripheral blood mononuclear cells (PBMC) from CHF patients (n=8) and healthy controls (n=8). Real-time quanti...
