Nature Reviews: Immunology, 4(9), 725-736. The prion's elusive reason for being. 1993-2004. If that's not bad enough, mutated prions can't easily be killed by heat or radiation, meaning once they've come into contact with something like surgical tools, they can potentially spread to other patients. Although they start out as harmless brain proteins, when prions become misfolded, they turn into contagious pathogens that recruit any other prions they come into contact with, grouping together in clumps that damage other cells and eventually cause the brain itself to break down. Molecular basis of cerebral neurodegeneration in prion diseases. A review of the scientific literature as it pertains to Gulf War Illnesses (Vol. The most frightening possibility would be the use of Prions to get rid of enemies in large regions of ongoing conflicts or political separatist wars.
