Prion Replication Depends On The Presence Of A Protease
Prion Replication Depends On The Presence Of A Protease. The abnormal forms actively degrade normal host cell proteases. It was also shown that the prion incubation time depends on the degree of protease resistance of prp sc in each such strain.
Expression analysis of FLAGtagged mouse prion proteins. A from www.researchgate.net
Two different prion strains from hamster (263k and hyper) and three from mouse (me7, rml, and 301c) were assayed for protease resistance in the presence (+) or absence (−) of 150 m m nacl. Indeed, the pmca technology is based on the assumption that prion replication depends on the formation and multiplication of oligomeric seeds 31, 59. 24 for conversion, it is thought that.

Prion aggregates are extremely stable and accumulate in infected tissue, causing tissue damage and cell death. The replication process is specific, the produced prp sc is homologous to that in the inoculum and determines the neurological disease observed in the transgenic mice.
