Abstract Tumor necrosis factor (TNF)-α promotes rheumatoid arthritis (RA) symptoms, including inflammation and bone erosion. The role of TNF-α in RA is considered to be complex because cytokine is responsible for a wide-range of functions, such as activation of immune cells, stimulation of osteoclast differentiation, and induction of cellular ...

Immunology Letters, 1994
Eight murine anti-TNF alpha monoclonal antibodies (mAb) were produced after immunization of BALB/c mice with rhTNF alpha. Six of these mAbs were able to neutralize cytotoxic activity of TNF alpha against L929 cells. Two other mAbs had no neutralizing effect. Epitope mapping studies were performed by ELISA and by using a BIAcore system (Pharmacia).

Tumor Necrosis Factor-Alpha Antagonist-Induced Sarcoidosis
JCR: Journal of Clinical Rheumatology, 2010Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Tumor necrosis factor (TNF)-alpha is an important player in granuloma formation, and recent clinical trials have investigated the efficacy of TNF-alpha inhibitors in sarcoidosis. Paradoxically, there are several case reports in the medical literature describing the development of ...

Production of Tumor Necrosis Factor-Alpha in Patients on Hemodiafiltration
Nephron, 1992The systemic production of tumor necrosis factor (TNF)-alpha was evaluated in uremic patients before and after hemodiafiltration (HDF) and paired filtration dialysis (PFD) and in the interdialytic period. Both HDF and PFD were performed using polysulfone dialyzers with either standard or ultrapure dialysis fluid.

Bioassay for Tumor Necrosis Factors-alpha and -beta
Molecular Biotechnology, 2000Tumor necrosis factor (TNF) is a central cytokine in the pathogenesis of septic shock and other inflammatory states. Assay by immunoassay is convenient, but, because of circulating soluble receptors, does not accurately reflect biological activity of the cytokine.

Role of lipopolysaccharide and tumor necrosis factor-alpha in induction of hepatocyte necrosis
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1995The occurrence of acute hepatic failure during systemic inflammatory response syndrome (SIRS) is related to the extent of hepatocyte (HC) damage and cell death resulting from necrosis or apoptosis. We hypothesized that proinflammatory mediators such as lipopolysaccharide (LPS) and tumor necrosis factor-alpha (TNF-alpha) can, either directly or ...

The regulation of circadian clock by tumor necrosis factor alpha
Cytokine & Growth Factor Reviews, 2019All organisms display circadian rhythms which are under the control of the circadian clock located in the hypothalamus at the suprachiasmatic nucleus, (SCN). The circadian rhythms allow individuals to adjust their physiological activities and daily behavior for the diurnal changes in the living environment. To achieve these, all metabolic processes are

Tuberculosis Infections and Tumor Necrosis Factor Alpha Antagonists
American Journal of Therapeutics, 2013The treatment of rheumatologic diseases with tumor necrosis factor-alpha antagonists has become common practice. Studies have demonstrated an increased risk of active tuberculosis with use of tumor necrosis factor-alpha antagonists. We aim to better define the risk of tuberculosis infection associated with tumor necrosis factor-alpha antagonists and to

Engineering a Synthetic Ligand for Tumor Necrosis Factor–Alpha
Bioconjugate Chemistry, 2011One approach to prepare protein binding ligands is to join two low-affinity ligands that bind different sites on the target protein to create a high-affinity bivalent ligand. This typically requires some knowledge of the ligand binding site and requires exquisite orientation of the ligands in order to achieve maximum binding affinity. Here, we explored

Induction of apoptosis in chondrocytes by tumor necrosis factor‐alpha
Journal of Orthopaedic Research, 2001AbstractTumor necrosis factor alpha (TNF‐α) induces apoptosis in a number of cell types and plays an essential role in bone remodeling, both stimulating the proliferation of osteoblasts and activating osteoclasts. During endochondral ossification, apoptosis of chondrocytes occurs concurrently with new bone formation and the resorption and replacement ...
