From what I remember on the topic, we do not have a good grasp on prions disease. There is a good chance that some other diseases in history may have actually been misdiagnosed prions disease. It can present as a form of dementia and the incubation period can be so long that many people are middle-aged before symptoms occur.
Tissue of the brain and spine are better for Prions propagation. Prions cause other proteins to misfold themselves. The proteins they affect are related to brain matter.
