Asthma is a chronic inflammatory and remodeling disorder of the airways, in which many cells, cellular elements, and cytokines play important roles. The role of tumor necrosis factor-α (TNF-α) in asthma is unclear in Pakistani population. The aim of this study was to assess the relationship between TNF-α-308 polymorphism and asthma. Polymorphism of TNF-α (G-308-A locus; rs 1800629) in 329 asthm...

As a kind of chronic inflammatory diseases, Rheumatoid arthritis (RA) has low cure rate and easy recurrence. It widely reported that abnormal activation mitogen-activated protein kinase (MAPK) nuclear factor kappa-B (NF-κB) signaling pathways are associated with the development RA inflammation. Blocking rheumatoid fibroblast-like synoviocytes (RA-FLS) can delay RA. Ononin is natural isoflavone ...

Tumor necrosis factor-α (TNF-α) inhibitors are increasingly used in treatment of inflammatory disorders because of their immunomodulatory efficacy. Increased risk of infection is an adverse effect of anti-TNF-α therapy. The incidence rate and severity of herpes zoster is significantly higher in patients on anti-TNF-α therapy than in the general population. The clinical presentation of varicella...

Anti-tumor necrosis factor-α (anti-TNF-α) agents represent a major breakthrough for the therapeutic management of different autoimmune conditions. Noninfectious uveitis may lead to various sight threatening complications. Hence, from extrapolation of the benefit observed in autoimmune systemic diseases, anti-TNF-α agents are widely used in the treatment of noninfectious uveitis. However, their ...

A 36-year-old woman with no medical or surgical history was evaluated for weight loss. Abdominal computed tomography (CT) showed signs of Crohn's disease, which was later confirmed endoscopically. She was started on tumor necrosis factor-α (TNF-α) inhibitor therapy. Nine months after treatment, she experienced additional weight loss and a 7 x 8 x 8-cm mass on repeat CT. Biopsy revealed retroper...

The aim of the present study was to construct a fast-acting, eukaryotic expression vector in eukaryotic cells based on transmembrane-tumor necrosis factor‑α (TM‑TNF‑α) structure. Two types of recombinant eukaryotic expression vectors were constructed, pcDNA3.1-TM-enterokinase-TNF‑α and pcDNA3.1‑TM‑Factor Xa‑TNF‑α, according to the TNF‑α transmembrane segments. Following the generation of these ...

Introduction  Insulin-like growth factor I (IGF-I) which is produced in abundance in the normal adult liver, is deeply involved in hepatocyte survival, growth, and differentiation during liver development. IGF-I plays the roles via the receptor (IGF-IR) signaling pathway. IGF-IR unlike IGF-I is expressed strongly in the developing liver, but much more weakly in adults. Objective:  We hypothesi...

The contribution of the pro-inflammatory macrophagederived cytokines IL-1 and tumor necrosis factor (TNF)-α has been well established through their capacity to modulate cartilage and bone metabolism. On the one hand, IL-1 and TNF-α stimulate osteoblasts to secrete cytokines such as granulocyte–monocyte colony stimulating factor (GM-CSF) and IL-6, which in turn regulate osteoclast formation. Thi...

A synthetic method to prepare 3a,6-methanoisoindole esters efficiently by gold(I)-catalyzed tandem 1,2-acyloxy migration/Nazarov cyclization followed by Diels-Alder reaction of 1,4,9-dienyne esters is described. We also report the ability of one example to inhibit binding of tumor necrosis factor-α (TNF-α) to the tumor necrosis factor receptor 1 (TNFR1) site and TNF-α-induced nuclear factor κ-l...

objective(s):  chlorpyrifos (cp) is a broad-spectrum organophosphorus pesticide used extensively in agricultural and domestic pest control, accounting for 50% of the global insecticidal use. in the present study, protective effects of two selenium-enriched strong antioxidative medicines imod and angipars were examined in human lymphocytes treated with cp in vitro. materials and methods: isolate...
