A human poliovirus receptor (PVR) gene was used to generate transgenic mice that express PVR transcripts and poliovirus binding sites in a wide range of tissues. Intracerebral inoculation of PVR transgenic mice with poliovirus type 1, Mahoney strain, resulted in viral replication in the brain and spinal cord and development of paralytic poliomyelitis. P1/Mahoney did not replicate or cause paralysis in nontransgenic mice. PVR transgenic mice failed to develop clinical disease when inoculated intracerebrally with the live attenuated Sabin type 1 vaccine strain. These results demonstrate that the PVR is the major determinant of poliovirus host range in mice. Transgenic mice expressing human PVR should be useful for studying poliovirus neurovirulence, attenuation, and tissue tropism, and for development and testing of poliovirus vaccine strains.
This research output has an Altmetric Attention Score of 30. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 April 2025.
All research outputs
#1,656,707
of 34,043,423 outputs
Outputs from Cell
#5,565
of 19,448 outputs
Outputs of similar age
#272
of 22,952 outputs
Outputs of similar age from Cell
#4
of 126 outputs
Altmetric has tracked 34,043,423 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 95th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 19,448 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 62.5. This one has gotten more attention than average, scoring higher than 71% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 22,952 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 98% of its contemporaries.
We're also able to compare this research output to 126 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 96% of its contemporaries.
