Human CD155 (Polio Virus Receptor, PVR, Necl-5) is a 70 kd type I Ig superfamily molecule (1).1 It is involved in formation of intracellular junctions between epithelial cells.  Its ligands include CD226(DNAM-1), and CD96(TACTILE).  CD155 expression by tumor has been shown to be upregulated by Nitric Oxide(2).  High CD155 expression has recently been exploited to use engineered poliovirus to treat glioblastoma.
