Triggering of the dsRNA Sensors TLR3, MDA5, and RIG-I Induces CD55 Expression in Synovial Fibroblasts
BACKGROUND CD55 (decay-accelerating factor) is a complement-regulatory protein highly expressed on fibroblast-like synoviocytes (FLS). CD55 is also a ligand for CD97, an adhesion-type G protein-coupled receptor abundantly present on leukocytes. Little is known regarding the regulation of CD55 expression in FLS. METHODS FLS isolated from arthritis patients were stimulated with pro-inflammatory...
متن کاملImmunohistochemical Expression and Prognostic Value of CD97 and Its Ligand CD55 in Primary Gallbladder Carcinoma
BACKGROUND CD97 as a member of the EGF-TM7 family with adhesive properties plays an important role in tumor aggressiveness by binding its cellular ligand CD55, which is a complement regulatory protein expressed by cells to protect them from bystander complement attack. Previous studies have shown that CD97 and CD55 both play important roles in tumor dedifferentiation, migration, invasiveness, a...
متن کاملExpression and prognostic value of CD97 and its ligand CD55 in pancreatic cancer
CD97 is a member of the epidermal growth factor-seven transmembrane family. It affects tumor aggressiveness by binding its cellular ligand CD55 and exhibits adhesive properties. Previous studies have shown that CD97 and CD55 are involved in the dedifferentiation, migration, invasiveness and metastasis of tumors. However, little is known regarding the roles of CD97 and CD55 in pancreatic cancer....
متن کاملThe seven-span transmembrane receptor CD97 has a cellular ligand (CD55, DAF)
CD97 is an activation-induced antigen on leukocytes with a seven-span transmembrane (7-TM) region homologous to the secretin receptor superfamily. However, in contrast to this group of peptide hormone receptors, CD97 has an extended extracellular region with three EGF domains at the NH2 terminus, two of them with a calcium binding site. By demonstrating that lymphocytes and erythrocytes specifi...
متن کاملCostimulation via CD55 on human CD4+ T cells mediated by CD97.
Decay-accelerating factor (CD55) is a complement regulatory protein, which is expressed by most cells to protect them from complement-mediated attack. CD55 also binds CD97, an EGF-TM7 receptor constitutively expressed on granulocytes and monocytes and rapidly up-regulated on T and B cells upon activation. Early results suggested that CD55 could further enhance T cell proliferation induced by ph...
