Tumor necrosis factor receptor-associated factor 2 (TRAF2) is a critical mediator of tumor necrosis factor-α (TNF-α) signaling. However, the regulatory mechanisms of TRAF2 are not fully understood. Here we show evidence that TRAF2 requires brefeldin A-inhibited guanine nucleotide-exchange factor 1
Human placental membranes exhibited high-affinity receptors for tumor necrosis factor (TNF) (Kd = 5.6 x 10(-10) M) with a density of 1.2-1.7 x 10(10) sites/mg protein. The receptors were solubilized from these membranes with 1% Nonidet P-40, and the solubilized receptor was adsorbed to Con
The development of sepsis is multifactorial. Tissue damage and organ dysfunction may be caused not only by the microorganisms but also by the inflammatory mediators released in response to the infection. Interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) levels in serum are well known to be
We have investigated the modulation of tumor necrosis factor (TNF)-mediated tumor cell lysis by cAMP. Among a panel of human breast tumor cell lines, MCF7 and MDA MB 231 were shown to be, respectively, sensitive and resistant to TNF-mediated cell lysis in vitro. 125I-labeled TNF-binding experiments
Guanine 7-N-oxide was shown to have synergistic activity in combination with neplanocin A against a rhabdovirus, infectious hematopoietic necrosis virus (IHNV), as reported previously. We examined further the antiviral activity of guanine 7-N-oxide in combination with other nucleoside antibiotics
A novel electrochemical immunosensor for the detection of tumor necrosis factor-alpha (TNF-alpha) based on poly(guanine)-functionalized silica nanoparticles (NPs) label is presented. The detection of mouse TNF-alpha via immunological reaction is based on a dual signal amplification: (1) a large
Transmembrane signalling mechanisms of tumor necrosis factor alpha (TNF alpha) were examined with special reference to the involvement of G-protein, in intact and permeabilized murine osteoblast-like cells. TNF alpha stimulated the release of 3H radioactivity from intact cells labeled with
Glioblastoma (GB) is the highest grade of primary adult brain tumors, characterized by a poorly defined and highly invasive cell population. Importantly, these invading cells are attributed with having a decreased sensitivity to radiation and chemotherapy. TNF-like weak inducer of apoptosis
Hemophagocytic syndrome (HPS) is frequently associated with hematopoietic stem cell transplantation and is treated with some benefit derived from TNF-α inhibitors. However, the mechanisms of how HPS occurs and how a TNF-α inhibitor exerts some benefit to HPS management have remained unclear. We
BACKGROUND
Rheumatoid arthritis (RA) is characterized by a progressive joint damage mediated mainly by tumor necrosis factor alpha (TNFalpha). We investigated the relationship of TNFalpha-308 and -238 polymorphisms with messenger RNA (mRNA) expression and soluble TNFalpha (sTNFalpha) in 50 RA and
OBJECTIVE
Over-expression of tumor necrosis factor-alpha (TNF-α) plays a pathological role in chronic periodontitis (CP) and rheumatoid arthritis (RA), which might be regulated by the epigenetic mechanism. The aim of the present study was to evaluate whether there is a unique methylation profile of
OBJECTIVE
To determine whether the tumor necrosis factor alpha (TNFA) -308 guanine-to-adenosine polymorphism and/or the shared epitope (SE) is associated with radiographic damage in patients with early rheumatoid arthritis (RA).
METHODS
The cohort consisted of 189 patients with early seropositive RA
Acne is a multifactorial, chronic inflammatory disease of pilosebaceous unit in which cytokines have been implicated in the pathogenesis. Although it is thought to be an inherited disease, there are limited data supporting the relevant genetic elements. Tumor necrosis factor-alpha (TNF-alpha) is one
Tumor-necrosis-factor alpha (TNF-alpha) is a major mediator of the inflammatory immune response and may play an important role in the pathogenesis and progression of Multiple Sclerosis (MS). Increased TNF-alpha levels of cerebrospinal fluid (CSF) and peripheral blood were found in patients with
Guanine 7-N-oxide produced by Streptomyces sp. was found to inhibit in vitro the replication of herpes virus (Oncorhynchus masou virus, OMV), rhabdo virus (infectious hematopoietic necrosis virus, IHNV) and a bi-segmented double-strand virus (infectious pancreatic necrosis virus, IPNV) derived from
