Activity summary

The PVRIG also known as CD112R is a cell surface receptor involved in immune responses. It has a molecular mass of approximately 38 kDa. Expressed mainly in immune cells including T cells and natural killer (NK) cells PVRIG binds with high affinity to its ligand CD112. This interaction modulates immune cell function by transmitting inhibitory signals that downregulate immune activation serving as a potential immune checkpoint.

Biological function summary

PVRIG impacts immune cell behavior and is part of the inhibitory receptor family. Its primary role is to fine-tune the immune response by decreasing overactivation helping to maintain immune homeostasis. PVRIG interacts with other immune inhibitory receptors like TIGIT and PD-1 forming a complex network that suppresses overactive T cell responses. This process is important for preventing autoimmune reactions while allowing normal immune surveillance.

Pathways

PVRIG participates in immune checkpoint pathways that influence T cell regulation. It plays a role in the immune checkpoint receptor pathway which is pivotal for controlling immune tolerance and immune-mediated inflammation. Within these pathways PVRIG works closely with other receptors like PD-1 forming a blockade that maintains the balance of immune activation and inhibition and participates in the immune synapse during antigen presentation.

Associated diseases and disorders

PVRIG is relevant to cancer and autoimmune diseases. Its expression on T cells can be upregulated in tumor environments contributing to immune escape in cancers like melanoma. The PVRIG-CD112 interaction competes with other pathways such as TIGIT and CD112 further impacting tumor immune evasion. In autoimmune diseases PVRIG may prevent excessive immune responses linking it to conditions like rheumatoid arthritis where altered immune regulation occurs.
