Abstract
We compared the host cell range of T-lymphotropic feline leukemia virus (FeLV-T) with that of FeLV subgroup B (FeLV-B) by pseudotype assay in the presence of FeLIX, a truncated envelope glycoprotein of endogenous FeLV. Although both viruses use Pit1 as a receptor and FeLIX does not hamper FeLV-B infection by receptor interference, the host ranges of FeLV-T and -B were not exactly the same, suggesting a different Pit1 usage at the post-binding level. A comparison of Pit1 sequences of various mammalian species indicated that extracellular loop 1 in a topology model deduced with the PHD PredictProtein algorism may be one of the regions responsible for efficient infection by FeLV-T.
