PVR

PVR (Poliovirus Receptor): PVR, also known as the poliovirus receptor, is a transmembrane glycoprotein crucial for viral entry and infection by certain viruses, including poliovirus and related enteroviruses. Beyond its role as a viral receptor, PVR plays essential roles in cell-cell adhesion, immune response modulation, and tissue homeostasis. It serves as a key component of adherens junctions and tight junctions, contributing to the integrity of epithelial and endothelial barriers. Additionally, PVR interactions with its ligands, such as TIGIT and DNAM-1, regulate immune cell activation and function, impacting both innate and adaptive immune responses. Dysregulation of PVR expression or function has...
