Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which plays crucial roles in pathogenesis of inflammatory diseases. The current study aimed to investigate the binding abilities of I44 and I49 domain antibodies to TNF-α. The dAbs were expressed in bacterial expression system and purified by affinity chromatography using Ni-sepharose column. The expression and purity of the protei...

objective(s): acquisition of tnf-α resistance plays role in the onset and growth of malignant tumors. previous studies have demonstrated that mcf-7 cell line and its doxorubicin resistant variant mcf-7/adr are resistant against the cytotoxic effects of tnf-α. in this study, we investigated the role of akt activation in resistance of mcf-7 and mcf-7/adr against tnf-α cytotoxicity. materials and ...

Background: Leishmania is a significant health problem in many parts of the world. Tumor necrosis factor (TNF) plays an essential role in Leishmania major infections. Objective: To study the pro-inflammatory cytokines and antioxidants in four groups of cutaneous leishmaniasis patients. Methods: 39 patients were divided into four groups of: 1) active (acute phase of treatment); 2) non-healing (r...

introduction: effects of immediate tnf-α exposure on phenotype and function of dendritic cells (dcs) derived from cord blood mono nuclear cells materials and methods: umbilical cord blood mncs were isolated from healthy mothers and were divided into tnf(+( and tnf (-) groups. both were cultured using scf, flt3l, gm-csf and il-4. but, three ng/ml of tnf-α was first added in the culture of tnf(+(...

The present study was conducted to evaluate the expression of caspase-3, caspase-9, growth differentiation factor-9 (GDF-9) and insulin factor-1 (IGF-1) genes in oocytes cultured vitro with optimum elevated doses amphiregulin (50 ng 150 ng), neuregulin-1 (25 ng) tumor necrosis factor-α during maturation based on results effects AREG or NRG-1 TNF-α concentration which caused significant effect, ...

Background: Generation of monocyte-derived dendritic cells (MDDC) is induced in the presence of GM-CSF and IL-4, and a maturation stimulus is added to the monocyte culture to obtain mature Dendritic Cells (DCs) suitable for therapy. TNF-α is the most common cytokine used for activating DCs and generating mature MDDC either alone or in combination with other cytokines. Objective: To compare effe...

background: leishmania is a significant health problem in many parts of the world. tumor necrosis factor (tnf) plays an essential role in leishmania major infections. objective: to study the pro-inflammatory cytokines and antioxidants in four groups of cutaneous leishmaniasis patients. methods: 39 patients were divided into four groups of: 1) active (acute phase of treatment); 2) non-healing (r...

Objective Objectives: The present study was designed to evaluate the serum lipid profile and Tumor Necrosis Factor alpha (TNF-ɑ) level in diabetic rats at the time of implantation. Type 2 diabetes mellitus (T2DM) could affect various systems, including innate immune system and causes chronic low-grade inflammation which increases the level of TNF-ɑ. Furthermore, T2DM is often accompanied by imp...
