The effects of the TNF- α blockers infliximab or etanercept on the levels of TNF- α , TNF-receptor 1 (TNF-R1), and TNF-receptor 2 (TNF-R2), as well as the levels of the inflammation markers CRP and IL-6, were measured in ankylosing spondylitis (AS) and rheumatoid arthritis (RA) patients receiving treatment with either compound. We found that RA patients tend to have higher levels of TNF- α than...
Consider Hankel operators Hf on the weighted Bergman space L 2 a(B, dvα). In this paper we characterize the membership of (H∗ fHf ) s/2 = |Hf | in the norm ideal CΦ, where 0 < s ≤ 1 and the symmetric gauge function Φ is allowed to be arbitrary.
background: infertility is a problem concerning 10-15% of the individuals in the fertile period. this study investigated effects of proinflammatory factors as well as lipid hydroperoxides (lpo) levels upon in vitro fertilization (ivf) success. materials and methods: in this prospective, non-randomized, controlled clinical study, sera obtained from 26 fertile (group-1), 26 infertile women before...
Chronic lymphocytic leukemia is a malignancy of mature B cells that strongly depend on microenvironmental factors, and their deprivation has been identified as a promising treatment approach for this incurable disease. Cytokine array screening of 247 chronic lymphocytic leukemia serum samples revealed elevated levels of tumor necrosis factor (TNF) receptor-1 which were associated with poor clin...
Respiratory virus infection evokes a potent T cell response which may result in a considerable insult to the structural and functional integrity of the gas exchange units of the lung. Alveolar antigen recognition by CD8+ T lymphocytes results in significant injury which is critically dependent upon TNF-α expressed by the CD8+ T cells, and largely dependent upon TNF-receptor 1 (TNF-R1) expressio...
Whereas there is ample evidence for involvement of the p55 tumor necrosis factor (TNF) receptor (p55-R) in the cytocidal effect of TNF, the role of the p75 TNF receptor (p75-R) in this effect is a matter of debate. In this study, we probed the function of p75-R in cells sensitive to the cytotoxicity of TNF using a wide panel of antibodies (Abs) against the receptor's extracellular domain. Two d...
At the cellular level, the multifunctional cytokine tumor necrosis factor (TNF) modulates growth and activates genes through various intermediates, including protein kinases, protein phosphatases, reactive oxygen intermediates, phospholipases, proteases, sphingomyelinases, and transcription factors. Unlike many cytokine receptors, however, the cytoplasmic domain (CD) of the TNF receptors lacks ...
TNF-alpha is the dominant cytokine in inflammatory osteolysis. Using mice whose BM stromal cells and osteoclast precursors are chimeric for the presence of TNF receptors, we found that both cell types mediated the cytokine's osteoclastogenic properties. The greater contribution was made, however, by stromal cells that express the osteoclastogenic cytokine M-CSF. TNF-alpha stimulated M-CSF gene ...
