Bovine Spongiform Encephalopathy
Iatrogenic (iCJD)
hormones from cadaver pituitaries, contamination of grafts or surgical instruments, and corneal transplants
(Got to clean the instruments!! serious cleaning)
Familial (fCJD)
large number of mutations in PRNP gene with different disease phenotypes
Sporadic (sCJD)
etiology is unknown, no known risk factors
Inherited Prion diseases: what? where
Rare, inherited mutation in PRNP gene
Resulting in PrPSc
PrpSC: what is it
forms beta sheets
converts PrPC into amyloid plaques
(she referred to this as stacking hamburger boxes? why idk)
PrPC: what is it
forms alpha helix
PrPC is a ubiquitously expressed glycoprotein involved in cell growth and maintenance
Chronic-Wasting Disease (CWD)
Happens in deer and elk
Transmissible Spongiform Encephalopathy (eat the deer)
