We have shown recently that by acting on the thyroid-stimulating hormone (TSH) receptor (TSHR), TSH negatively regulates osteoclast differentiation. Both heterozygotic and homozygotic TSHR null mice are osteopenic with evidence of enhanced osteoclast differentiation. Here, we report that the accompanying elevation of TNF , an osteoclastogenic cytokine, causes the increased osteoclast differenti...
The dramatic responses tumors display to targeted therapies are limited by acquired or pre-existing mechanisms of therapy resistance. We recently discovered that androgen receptor blockade by the anti-androgen enzalutamide paradoxically enhanced metastasis and that these pro-metastatic effects were mediated by the chemoattractant CCL2. CCL2 is regulated by TNF, which is negatively regulated by ...
The atrial natriuretic peptide (ANP) is suggested to regulate inflammatory response by alteration of macrophage functions. The aim of this study was to investigate whether ANP influences production of TNF-alpha. TNF-alpha production in murine bone marrow-derived macrophages was induced by LPS, and TNF-alpha secretion (+/-ANP) was determined by L929 bioassay. ANP dose dependently (10-8-10-6 M) i...
BACKGROUND Retransfused cardiotomy suction blood contains elevated inflammatory markers and is a bypass independent source of inflammatory mediators. We hypothesized that, during off-pump coronary artery bypass (OPCAB) grafting surgery, avoiding retransfusion of unwashed cardiotomy suction blood would beneficially alter both urinary and plasma cytokine concentrations and be renoprotective. ME...
Excess lipid droplets are frequently observed in arterial endothelial cells at sites of advanced atherosclerotic plaques. Here, the role tumor necrosis factor alpha (TNF?) modulating low-density lipoprotein (LDL) content confluent primary human aortic (pHAECs) was investigated. TNF? promoted an up to 2 folds increase cellular cholesterol, which resistant ACAT inhibition. The cholesterol associa...
TNF participates in the induction of nitric oxide (NO) production and macrophage activation, leading to the elimination of intracellular pathogens. We previously found that TNF receptor p55-deficient mice (TNFRp55-/-) control replication of Leishmania major in vivo but fail to resolve their lesions. Here we report that mice lacking the p75 receptor (TNFRp75-/-) or both receptors (TNFRp55p75-/-)...
