Macrophage-induced bystander effects have been implicated as an important mediator of chromosomal instability and colon cancer triggered by Enterococcus faecalis, a human intestinal commensal bacteria. There is little understanding about how inflammatory cytokines mediate bystander effects, but questions in this area are important because of the pivotal contributions made by inflammatory proces...

Tumour necrosis factor-α (TNF) is an inflammatory cytokine that is elevated in a number of autoimmune diseases including immune thrombocytopenia (ITP), a bleeding disorder characterized by low platelet counts. In vitro TNF blockade increases expansion of the regulatory T cell (Treg) IKZF2 (also termed Helios) subset in T cell-monocyte cocultures from healthy donors, but its role on proliferativ...

Familial combined hyperlipidemia (FCHL) is the most commonly inherited hyperlipidemia in man, with a frequency of +/-1% in the general population and approximately 10% in myocardial infarction survivors. A genomic scan in 18 Dutch FCHL families resulted in the identification of several loci with evidence for linkage. One of these regions, 1p36.2, contains TNFRSF1B which encodes one of the tumor...

Although it is known that tumor necrosis factor receptor (TNFR) signaling plays a crucial role in vascular integrity and homeostasis, the contribution of each receptor to these processes and the signaling pathway involved are still largely unknown. Here, we show that targeted gene knockdown of TNFRSF1B in zebrafish embryos results in the induction of a caspase-8, caspase-2 and P53-dependent apo...

OBJECTIVE This study aimed to analyze the predominant expression of the variable region of T cell receptor (TRBV) and determine whether NAV3 or TNFRSF1B gene mutation involved in the pathogenesis of MF. RESULTS TRBV5-7 expression increased from the normal, early-stage to advanced-stage lesion in MF patient. By contrast, TRBV2 decreased with the lesion developed. We found no mutations of NAV3 ...

Osteoporosis is a multifactorial disease with a strong genetic component characterized by reduced bone density and increased fracture risk. A candidate locus for regulation of hip bone mineral density (BMD) has been identified on chromosome 1p36 by linkage analysis. One of the positional and functional candidate genes located within this region is the tumour necrosis factor receptor superfamily...
