Immunopharmacology Comments
The PVR protein (a.k.a. CD155) is a single-pass immunoglobulin-like adhesion molecule. It plays a role in modulating natural killer and T cell-mediated immunity. PVR expression is upregulated in response to exposure to different stimuli, such as Toll-like receptor activation or T cell receptor stimulation [5,9]. It is a ligand for three receptors that are commonly found on NK cells: CD96 [2], TIGIT (which are both co-inhibitory receptors) and DNAM-1 (CD226; a co-stimulatory receptor) [10]. It exhibits the highest binding affinity for CD96 [3]. Interactions with these receptors culminate in the formation of a mature immunological synapse which promotes NK cell activation and cytoxicity.

PVR is frequently overexpressed in human malignant tumours as a mechanism of immunoevasion and contributes to tumour progression and metastasis [7]. Subsequently, PVR is being explored as a novel immuno-oncology therapeutic target [1,4,6,8,11-12].

General Comments
PVR was originally identified as the host cell receptor used by the poliovirus to facilitate viral entry. Poliovirus binds to one of the protein's extracellular domains. The PVR protein normally functions as an immunoglobulin-like adhesion molecule that is involved in cell motility, and natural killer and T cell-mediated immunity. It can be produced as a membrane anchored protein or in a soluble form that lacks the transmembrane domain, and is generally expressed at low levels in healthy tissues.
The PVR protein contains an immunoglobulin (Ig)-like domain that resembles the antibody variable domain, that has been coined the 'V-set domain'. The genes for all human V-set domain containing proteins are listed in HGNC gene group 590.
