What bank voles can teach us about prion disease transmission and neurodegeneration

Transmission of prions between species is inefficient, and only a small proportion of exposed recipients become sick within their lifetimes. A new study takes a close look at one exception to this rule: bank voles appear to lack a species barrier for prion transmission, and their universal susceptibility turns out to be both informative and useful for the development of strategies to prevent prion transmission.
