1 The Pathological Protein Ch 4, 5
BY Nicholas Toney

2 Connecting The Holes An Uncanny Resemblance Studying Scrapie
Hadlow - was Scrapie transmissible? Studying Scrapie Cuille and Chelle 15 month incubation period

3 Trying Transmissions Hadlow's Letter and Patuxent
Georgette's Sacrifice "Their loss... was felt by the staff“ The Kuru-CJD Link CJD experiments at Patuxent Establishment of TSEs

4 End of an Epidemic Cannibalism in Kuru Cases of Kuru in early 2003
Implications? Nobel Worthy Gajdusek "fretted" that Zigas and Gibbs were not included

5 The Birth of the Prion The Central Dogma

6 A Tough Invader Tikvah Alper The Elusive Agent Radiation experiments
High energy electrons Ultraviolet radiation The Elusive Agent Central Dogma maintained Thoertical model proposed by mathmeticain

7 TSE's New Player Pruisner Persevered New Methodology
Isolation of the Agent Protease Sensitivity Filtered at kDa250 Amino Acid Minimum Maximum of 50 nucleotides

8 The Virus Paradox

9 The Prion Proposal Controversy over Pruisner's work
Frank Masiarze refused Co-Authorship Nature and Lancet soon published rebuttals Fatal Filaments Patricia Merz Filaments associated with Scrapie Manuelidis CJD confirmed Amyloid plaques?

10 The Normal and the Diabolical
DNA sequencing as a tool to find the causative agent Pruisiner found that the scrapie agent existed in healthy and infected brains Proteinase K - protein differentiation
