Glutathione peroxidase (GPX) activity in blood of ewes on farms in different scrapie categories in Iceland

open access: yesActa Veterinaria Scandinavica, 2008
Background Preliminary studies indicated decreased glutathione peroxidase (GPX) activity in blood of ewes on scrapie-afflicted farms. Other studies have shown decreased GPX activity in brain of prion-infected mice and in prion-infected cells in vitro ...
