Abstract

Considerable information on the functions of prion protein (PrP) has been accumulated. One experimental approach is the use of PrP gene-knockout mice and derived cell lines. This approach has contributed to elucidating the functions of cellular prion protein (PrPC), such as its anti-oxidative and anti-apoptotic roles. This review will introduce the recent advances in prion biology made possible by the availability of these tools.

Keywords: Prion protein, PrP-knockout mice, PrP-deficient cells, apoptosis, oxidative stress
