In mammals the endothelin (ET) family comprises three endogenous isoforms ET-1 ET-2 and ET-3 These endothelium-derived peptides perform their functions via two endothelin receptors classified as EDNRA and EDNRB EDNRA receptors are mainly localized in the vascular smooth muscle cells where they are the predominant sub-type and mediate vasoconstriction and proliferation Selective EDNRA antagonists are effective in the treatment of heart failure essential hypertension pulmonary hypertension and atherosclerosis

CD155 commonly known as PVR (poliovirus receptor) and Necl-5 (nectin-like molecule-5) is a type I transmembrane single-span glycoprotein and belongs to the nectins and nectin-like (Necl) subfamily CD155 was originally identified based on its ability to mediate the cell attachment and entry of poliovirus (PV) an etiologic agent of the central nervous system disease poliomyelitis The normal cellular function is in the establishment of intercellular adherens junctions between epithelial cells CD155 may assist in an efficient humoral immune response generated within the intestinal immune system It s been shown that CD155 can be recognized and bind by DNAM-1 and CD96 which promotes the adhension migration and NK-cell killing Thus inducing cell-mediated tumor-specific immunity

CASR is a calcium-sensing receptor and plays an important role in regulating PTH secretion It is expressed in many different tissues such as parathyroid pancreatic islet and insulinoma cells breast gastrinoma cells pituitary keratinocytes and human colon epithelial cells CASR Inhibits PTH secretion and parathyroid cellular proliferation in parathyroid glands or cells and also inhibits proliferation of colonic crypt cells Besides it can stimulate PTHrP secretion in prostate cell line and stimulate calcitonin secretion from thyroidal C-cells

Herpes Virus Entry Mediator (HVEM) is a transmembrane protein that is the receptor for TNFSF14 (also known as LIGHT) and is therefore referred to asTNFRSF14 HVEM is expressed broadly on immune cells such as T cells natural killer (NK) cells and monocytes The interaction of 3 molecules of LIGHT with three molecules of HVEM forms a hexameric complex that leads to the recruitment and retention of effector cells and activates NK cells to produce large amounts of IFN- and GM-CSF In addition to the canonical binding partner LIGHT HVEM can also bind to the inhibitory signaling protein B- and T- lymphocyte attenuator (BTLA) which suppresses immune responses Therefore the HVEM network plays an important role in regulating immunity and the behavior of lymphocytes
