Tumor necrosis factor receptor superfamily member 18 (TNFRSF18), also known as glucocorticoid-induced tumor necrosis factor receptor family-related protein (GITR); TNFRSF18 (also known as activation-inducible TNF receptor (AITR), glucocorticoid-induced tumor necrosis factor receptor family-related protein (GITR), CD357, GITR-D) has increased expression upon T-cell activation, and is thought to play a key role in dominant immunological self-tolerance maintained by CD25(+)CD4(+) regulatory T cells. In inflammatory cells, GITR expression indicates a possible molecular link between steroid use and complicated acute sigmoid diverticulitis; increased MMP-9 expression by GITR signaling might explain morphological changes in the colonic wall in diverticulitis. Its ligand, GITRL, activates GITR which could then influence the activity of effector and regulatory T cells, participating in the development of several autoimmune and inflammatory diseases, including autoimmune thyroid disease and rheumatoid arthritis. In systemic lupus erythematosus (SLE) patients, serum GITRL levels are increased compared with healthy controls. GITR and its ligand, GITRL, are possibly involved in the pathogenesis of primary Sjogren's syndrome (pSS). GITR is inactivated during tumor progression in Multiple Myeloma (MM); restoration of GITR expression in GITR deficient MM cells leads to inhibition of MM proliferation and induction of apoptosis, thus playing a pivotal role in MM pathogenesis and disease progression. Regulatory T-cells (Tregs) in liver tumor up-regulate the expression of GITR compared with Tregs in tumor-free liver tissue and blood. Regulatory single nucleotide polymorphisms (SNPs) in the promoter regions of the TNFRSF18 gene have been identified in a group of male Gabonese individuals exposed to a wide array of parasitic diseases such as malaria, filariasis and schistosomiasis, and may serve as a basis to study parasite susceptibility in association studies.

Tumor necrosis factor receptor superfamily member 5 (TNFRSF5) in teleosts; also known as CD40; TNFRSF5 (commonly known as CD40 and also as CDW40, p50, Bp50) is widely expressed in diverse cell types including B lymphocytes, dendritic cells, platelets, monocytes, endothelial cells, and fibroblasts. It is essential in mediating a wide variety of immune and inflammatory responses, including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. Its natural immunomodulating ligand is CD40L, and a primary defect in the CD40/CD40L system is associated with X-linked hyper-IgM (XHIM) syndrome. It is also involved in tumorigenesis; CD40 expression is significantly higher in gastric carcinomas and it is associated with the lymphatic metastasis of cancer cells and their tumor node metastasis (TNM) classification. Upregulated levels of CD40/CD40L on B cells and T cells may play an important role in the immune pathogenesis of breast cancer. Consequently, the CD40/CD40L system serves as a link between tumorigenesis, atherosclerosis, and the immune system, and offers a potential target for drug therapy for related diseases, such as cancer, atherosclerosis, diabetes mellitus, and immunological rejection. Salmon CD40 and CD40L are widely expressed, particularly in immune tissues, and their importance for the immune response is indicated by their relatively high expression in salmon lymphoid organs and gills.

Tumor necrosis factor receptor superfamily member 6B (TNFRSF6B), also known as decoy receptor 3 (DcR3); The subfamily TNFRSF6B is also known as decoy receptor 3 (DcR3), M68, or TR6. This protein is a soluble receptor without death domain and cytoplasmic domain, and secreted by cells. It acts as a decoy receptor that competes with death receptors for ligand binding. It is a pleiotropic immunomodulator and biomarker for inflammatory diseases, autoimmune diseases, and cancer. Over-expression of this gene has been noted in several cancers, including pancreatic carcinoma, and gastrointestinal tract tumors. It can neutralize the biological effects of three tumor necrosis factor superfamily (TNFSF) members: TNFSF6 (Fas ligand/FasL/CD95L) and TNFSF14 (LIGHT) which are both involved in apoptosis and inflammation, and TNFSF15 (TNF-like molecule 1A/TL1A), which is a T cell co-stimulator and involved in gut inflammation. DcR3 is a novel inflammatory marker; higher DcR3 levels strongly correlate with inflammation and independently predict cardiovascular and all-cause mortality in chronic kidney disease (CKD) patients on hemodialysis. Increased synovial inflammatory cells infiltration in rheumatoid arthritis and ankylosing spondylitis is also associated with the elevated DcR3 expression. In cartilaginous fish, mRNA expression of DcR3 in the thymus and leydig, which are the representative lymphoid tissues of elasmobranchs, suggests that DcR3 may act as a modulator in the immune system. Interestingly, in banded dogfish (Triakis scyllia), DcR3 mRNA is strongly expressed in the gill, compared with human expression in the normal lung; both are respiratory organs, suggesting potential relevance of DcR3 to respiratory function.

Tumor necrosis factor receptor superfamily member 21 (TNFRSF21), also known as death receptor (DR6); TNFRSF21 (also known as death receptor 6 (DR6), CD358, BM-018) is highly expressed in differentiating neurons as well as in the adult brain, and is upregulated in injured neurons. DR6 negatively regulates neurondendrocyte, axondendrocyte, and oligodendrocyte survival, hinders axondendrocyte and oligodendrocyte regeneration and its inhibition has a neuro-protective effect in nerve injury. It activates nuclear factor kappa-B (NFkB) and mitogen-activated protein kinase 8 (MAPK8, also called c-Jun N-terminal kinase 1), and induces cell apoptosis by associating with TNFRSF1A-associated via death domain (TRADD), which is known to mediate signal transduction of tumor necrosis factor receptors. TNFRSF21 plays a role in T-helper cell activation, and may be involved in inflammation and immune regulation. Its possible ligand is alpha-amyloid precursor protein (APP), hence probably involved in the development of Alzheimer's disease; when released, APP binds in an autocrine/paracrine manner to activate a caspase-dependent self-destruction program that removes unnecessary or connectionless axons. Increasing beta-catenin levels in brain endothelium upregulates TNFRSF21 and TNFRSF19, indicating that these death receptors are downstream target genes of Wnt/beta-catenin signaling, which has been shown to be required for blood-brain barrier development. DR6 is up-regulated in numerous solid tumors as well as in tumor vascular cells, including ovarian cancer and may be a clinically useful diagnostic and predictive serum biomarker for some adult sarcoma subtypes.

Tumor necrosis factor receptor superfamily member 11A (TNFRSF11A), also known as receptor activator of nuclear factor-kappaB (RANK); TNFRSF11A (also known as RANK, FEO, OFE, ODFR, OSTS, PDB2, CD26, OPTB7, TRANCER, LOH18CR1) induces the activation of NF-kappa B and MAPK8/JNK through interactions with various TRAF adaptor proteins. This receptor and its ligand are important regulators of the interaction between T cells and dendritic cells. The receptor is also an essential mediator for osteoclast and lymph node development. Mutations at this locus have been associated with familial expansile osteolysis, autosomal recessive osteopetrosis, and Juvenile Paget's disease (JPD) of bone. Alternatively spliced transcript variants have been described for this locus. Mutation analysis may improve diagnosis, prognostication, recurrence risk assessment, and perhaps treatment selection among the monogenic disorders of RANKL/OPG/RANK activation.
