Mouse CD155, also known as homolog of polivirus receptor (PVR), is the founding member of a subfamily of immunoglobulin-like adhesion receptors (nectins). Mouse CD155 is expressed on a wide variety of cells of hematopoietic origin apart from its existence on the epithelial cells. The engagement of CD155 with CD226 and CD96 induces cytotoxicity of NK cells and CTL.

Other Names: PVR (poliovirus receptor) homolog
Structure: 70 kd immunoglobulin-like molecule with three Ig-like domains.
Distribution: CD155 is expressed at cell junctions on the primary vascular endothelial cells. Moreover, mouse CD155 is highly expressed on DP thymocytes and expression level is dropped in peripheral single positive CD4+ and CD8+ T cells. CD155 can be detected on T reg, other activated T cells and on NKT cells. Resident monocytes express moderate amount of CD155, but upregulated its expression during inflammation. Other cells, such as IEL, neutrophils and subsets of B cells were found to express CD155 to varying extents.
Function: Apart from its function of adhering junction among contacting epithelial cells, the interaction of DNAM-1 (CD226) with its ligands CD155 and CD112 (nectin 2) induces cytotoxcity of NK cells and CD8+ T cells and cytokine secretion.
Ligand Receptor: CD226 (DNAM-1), CD96
