The cytoprotective effects of tumor necrosis factor are conveyed through tumor necrosis factor receptor-associated factor 2 in the heart.
BACKGROUND Activation of both type 1 and type 2 tumor necrosis factor (TNF) receptors (TNFR1 and TNFR2) confers cytoprotection in cardiac myocytes. Noting that the scaffolding protein TNF receptor-associated factor 2 (TRAF2) is common to both TNF receptors, we hypothesized that the cytoprotective responses of TNF were mediated through TRAF2. METHODS AND RESULTS Mice with cardiac-restricted ov...
متن کاملStimulus-dependent Synergism of the Antiapoptotic Tumor Necrosis Factor Receptor–associated Factor 2 (TRAF2) and Nuclear Factor κB Pathways
Tumor necrosis factor (TNF) signaling leads to pleiotropic responses in a wide range of cell types, in part by activating antiapoptotic and proapoptotic signaling pathways. Thus, although TNF can cause apoptosis and may prove useful in the treatment of malignancies, most cells are resistant to TNF-induced cell death unless de novo protein synthesis is inhibited. Previous studies suggested that ...
متن کاملTumor necrosis factor receptor-associated factor 2 mediates mitochondrial autophagy.
BACKGROUND Tumor necrosis factor (TNF) signaling protects against ischemia/reperfusion-induced cardiomyocyte death, in vitro, ex vivo, and in vivo. TNF-receptor-associated factor 2 (TRAF2), an E3 ubiquitin ligase, coordinates cytoprotective signaling downstream of both TNF receptors, via unclear mechanisms. Noting that TRAF2 is recruited to mitochondria, and that autophagic removal of ubiquitin...
متن کاملTumor necrosis factor receptor-mediated signaling pathways
T UMOR necrosis factor c~ (TNF) ~ and tumor necrosis factor ~ (lymphotoxin) are two cytokines produced primarily by macrophages and lymphocytes, respectively. These cytokines are recognized by the same cell surface receptors and are associated with similar biological activities. Some of the well-known TNF effects include septic shock, cytotoxicity, inflammation, and cachexia. The role of TNF in...
متن کاملAssociation of VNTR polymorphism of tumor necrosis factor receptor 2 (TNFRSF1B) with pulmonary tuberculosis
This study was designed to find out the impact of the variable number of tandem repeats (VNTR) of the tumor necrosis factor receptor 2 (TNFRSF1B) on pulmonary tuberculosis (PTB) risk in an Iranian population. This case-control study was done on 159 PTB patients and 158 healthy subjects. Bi-allelic TNFRSF1B VNTR was genotyped by polymerase chain reaction. Logistic regression analysis revealed no...
