Expression of the tumor necrosis factor receptor—associated factors 1 and 2 and regulation of the nuclear factor—kB antiapoptotic activity in human g…

Object. Tumor necrosis factor receptor (TNFR)—associated factors (TRAFs) are a recently established group of proteins involved in the intracellular signaling of the TNFR superfamily members. The TRAFs have been implicated in promoting cell survival through the activation of transcription factor nuclear factor (NF)—κB. The authors investigated the expression of NF-κB, caspase 3, TRAF1, TRAF2, and TRAF-associated NF-κB activator/TRAF—interacting protein (TANK/I-TRAF), a regulator of TRAF activity, in human gliomas. Methods. Tumor samples were obtained in 27 adult patients harboring seven low-grade gliomas, nine anaplastic astrocytomas, and 11 glioblastomas multiforme. The NF-κB activation was…
Functional relevance of soluble TNF-alpha, transmembrane TNF-alpha and TNF-signal transduction in gastrointestinal diseases with special reference to…

As a result of extensive clinical and basic research, the pivotal role of tumour necrosis factor (TNF) in the pathogenesis of chronic inflammatory diseases such as inflammatory bowel disease (IBD) has now generally been acknowledged. This has led to promising clinically effective anti-TNF-strategies. Of note, there is more and more evidence that TNF seems to play a key role in other gastrointestinal diseases including Helicobacter pylori infection, pancreatitis, viral hepatitis and toxic liver damage, too. The action of TNF at the cellular level is mediated by two cell surface receptors, TNF-R1 (p60) and TNF-R2 (p80). The function of these receptors and the downstream intracellular signal t…
