PURPOSE To elucidate a possible target of immunosuppressive agents widely used in the treatment of corneal disorders, the authors determined whether corneal cells are capable of expressing and releasing tumor necrosis factor-alpha (TNF alpha) on lipopolysaccharide (LPS) stimulation, and they investigated whether TNF alpha production can be modulated by pharmacologic agents. METHODS Trephined ...

A proinflammatory role for glycogen synthase kinase 3beta (GSK-3beta) has been demonstrated. Here, we addressed its roles on heat-inactivated Staphylococcus aureus-induced microglial inflammation. Heat-inactivated S. aureus induced tumor necrosis factor alpha (TNF-alpha) and nitric oxide (NO) production, at least in part, via a Toll-like receptor 2-regulated pathway. Neutralization of TNF-alpha...

Martin, Christian, Andrea Wohlsen, and Stefan Uhlig. Changes in airway resistance by simultaneous exposure to TNF-a and IL-1b in perfused rat lungs. Am J Physiol Lung Cell Mol Physiol 280: L595–L601, 2001.—Tumor necrosis factor (TNF)-a and interleukin (IL)-1b are formed simultaneously under inflammatory conditions such as asthma and acute respiratory distress syndrome. Here we investigated the ...

The in vivo production of interleukin (IL)-10, IL-6, IL-2, and tumor necrosis factor (TNF)-alpha in tumor samples was investigated by immunohistochemistry in 54 non-Hodgkin's lymphomas (NHLs). Respectively, 55, 89, 23, and 29% of tumor samples were found positive for IL-10, IL-6, IL-2, and TNF-alpha expression by immunohistochemistry. Using reverse transcription-PCR, the mRNA of IL-10 and IL-6 ...

Objectives: Nigella sativa is a medicinal plant that has long been used in traditional medicine for treating various conditions. Numerous animal studies provided evidences that the seed may elicit a broad anti-inflammatory/anti-oxidant activity. The aim of the present clinical trial was to evaluate anti-inflammatory and antioxidant properties of Nigella sativa oil in patients with rheumatoid ar...

Background: Tumor necrosis factor alpha (TNF-α) is a primary mediator of immune regulation and might be required in the early stages of DC development from CD34+ cells. However, details of optimal timing of exposure to TNF-α in DC development process in monocytes or non-purified hematopoitic cells are still lacking and clear benefits of this approach to the development of DCs remain to be valid...

Background: Aloes have been used as medicinal plants for centuries. The immunomodulatory effect of Aloe vera has previouslybeen shown. Meanwhile, TNF-α, as an inflammatory cytokine, plays an essential role in defense against invading pathogen. Objectives: In the present study, the effects of A. vera extract gel and its fractions were investigated on the TNF-α production bymacrophages against Ca...

Background: Periodontitis and rheumatoid arthritis (RA) share a number of clinical and pathologic features, one of which is the presence of the tumor necrosis factor alpha (TNF-α)-induced bone resorption that is involved in the pathogenesis of both. Objectives: To investigate the effect of TNF-α blockade on periodontal conditions in patients with active RA. Method: The periodontal statuses of 3...

A low transitional-1 B cell IL-10/TNF? ratio predicts rejection and supports preemptive intervention for patients after kidney transplantation.

Neointimal hyperplasia causes vascular stenosis and subsequent thrombosis, which result in vascular access failure in patients undergoing hemodialysis. Interleukin-10 (IL-10) and tumour necrosis factor-alpha(TNF-alpha) are involved in this inflammatory process. The aim of this study was to investigate the relationship between vascular access failure and various inflammatory markers including th...
