Implication

Experimental study demonstrates sensitive detection of TSE amyloid across animal and human tissues, suggesting utility for routine transmissible spongiform encephalopathy diagnosis.

Key Points

To evaluate an improved, high-yield purification and Western blot method for detecting and mapping disease-specific amyloid across humans and animals with transmissible spongiform encephalopathies.
Applied an improved extraction method to isolate scrapie-associated fibril (SAF) protein from 20 to 100 mg tissue samples.
Analyzed central nervous system and spleen specimens from orally and intracerebrally infected hamsters, infected squirrel monkeys, humans with sporadic Creutzfeldt-Jakob disease, sheep with scrapie, and cattle with bovine spongiform encephalopathy.
Achieved an extraction yield of 70%, permitting Western blot detection in 1 to 10 micrograms of brain tissue from infected hamsters as well as in individual terminal hamster spleens.
Detected disease-specific amyloid across all examined species, with human sporadic Creutzfeldt-Jakob disease samples exhibiting amyloid concentrations 1,000- to 10,000-fold lower than scrapie-infected hamster central nervous system tissues.
