This receptor is expressed on a variety of cell types including epithelial and endothelial cells immune cells and fibroblasts. Another name for PVR is Necl-5 which falls under the nectin-like molecule family. It acts as an adhesion molecule and contributes to cellular signaling and junctional complexes. The expression of PVR is widespread across multiple tissues but it exhibits stronger expression in areas such as the skin and the gastrointestinal tract.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe Poliovirus Receptor plays meaningful roles in immune response modulation and cell-cell adhesion. PVR interacts with components of the immune system and forms complexes with other proteins like CD226 and TIGIT. These interactions help regulate immune cell activities especially in the context of natural killer (NK) cells and T-cells. The CD155 protein also links to migration and proliferation processes which are essential for tissue formation and repair.\u003cbr\u003e\nPathways\u003cbr\u003e\nPVR is involved in the regulation of immune and signaling pathways. It fits into pathways like NK cell activation and T-cell inhibitory signaling which are important for maintaining immune tolerance and preventing autoimmunity. In these pathways PVR interacts closely with other immunoregulatory proteins including CD226 and TIGIT. The partnership of PVR with these proteins shapes the delicate balance between immune activation and suppression demonstrating a clear role in immune homeostasis.\u003cbr\u003e\nPVR relates to conditions such as cancer and viral infection. Its overexpression or altered signaling has been observed in several cancers where it may contribute to tumor growth and immune evasion. The interaction between PVR and its related protein TIGIT can affect antitumor immune responses complicating cancer progression. Additionally as its name suggests PVR binds to the poliovirus facilitating viral entry and spread during infection. This highlights the importance of PVR not only in pathogenic interactions but also in broader immune response contexts.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843832893609,"sku":"ab220561","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab220561","provider":"Iright","version":"1.0","type":"link"}
