The Poliovirus type 1 also known as PV1 is one of the three serotypes of poliovirus a pathogen belonging to the Picornaviridae family. It has a capsid made of icosahedral symmetry with a diameter of approximately 30 nm. PV1 is primarily expressed within the human host cells specifically affecting motor neurons. Its genome consists of a single-stranded positive-sense RNA encoding a polyprotein that processes into viral structural proteins and non-structural proteins essential for replication and assembly.

Biological function summary

The poliovirus type 1 acts as the causative organism of poliomyelitis commonly referred to as polio. This virus initiates infection by binding to the CD155 receptor on susceptible host cells leading to the entry into the host and subsequent replication. Poliovirus does not function as part of a larger complex but relies on host cell machinery to facilitate its replication and protein synthesis. Through its activity the virus disrupts normal cellular functions causing paralysis and other symptoms associated with polio.

Pathways

Poliovirus type 1 infection involves the hijacking of the host’s cellular processes. The virus manipulates the protein synthesis pathway to translate its own RNA into proteins efficiently often at the expense of the host cell's own proteins. It interacts with several host proteins including eukaryotic initiation factors (eIF) essential for redirecting cellular machinery towards viral protein production. Additionally the virus disrupts the cell's cytoskeletal pathway destabilizing cellular structure and aiding the release of new viral particles.

Poliovirus type 1 predominantly causes poliomyelitis a disease marked by inflammation of the spinal cord that can lead to paralysis. The disease is most notorious for its manifestation as acute flaccid paralysis in affected individuals. During its progression PV1's interaction with the CD155 receptor not only assists viral entry but can trigger immune responses linked to disease pathogenesis. Interaction with the immune system is critical as the virus' capacity to evade immune detection partly attributes to its virulence complicating disease control efforts.
