背景介绍
Tumor necrosis factor Receptor superfamily member 1B (TNFRSF1B) is a member of the tumor necrosisfactor Receptor superfamily. Human TNF RII contains four cysteinerich repeats in its ECD, which shares 58%and 56% amino acid sequence identity with the mouse and rat orthologs, respectively.TNF RII is expressedpredominantly on cells of the hematopoietic lineage, such as T and natural killer cells, as well as onendothelial cells, microglia, astrocytes,neurons, oligodendrocytes, cardiac myocytes, thymocytes, andmesenchymal stem cells.TNF RII binds to the membranebound forms of TNFα and Lymphotoxinα/ TNFβ;soluble TNF is thought to signal predominately through TNF RI.Soluble TNF RII is believed to inhibit TNFbiological activity by binding TNF thereby preventing it from activating membrane TNF Receptors.
