A prion / ˈ p r iː ɒ n / ⓘ is a misfolded protein that induces misfolding in normal variants of the same protein, leading to cellular death.Prions are responsible for prion diseases, known as transmissible spongiform encephalopathy (TSEs), which are fatal and transmissible neurodegenerative diseases affecting both humans and animals.
Transmissible spongiform encephalopathies (TSEs), also known as prion diseases, [1] are a group of progressive, incurable, and fatal conditions that are associated with the prion hypothesis and affect the brain and nervous system of many animals, including humans, cattle, and sheep.
Women and children usually consumed the brain, the organ in which infectious prions were most concentrated, thus allowing for transmission of kuru. The disease was therefore more prevalent among women and children. The epidemic likely started when a villager developed sporadic Creutzfeldt–Jakob disease and died. When villagers ate the brain ...
Chronic wasting disease is a progressive, fatal prion disease that affects the brain, spinal cord and many other tissues of farmed and free-ranging deer, elk, and moose.
Versions of prion diseases can affect humans, but it’s more typical among animals. ... Chronic wasting disease is thought to be spread between the animals directly or indirectly through bodily ...
Chronic wasting disease (CWD), sometimes called zombie deer disease, is a transmissible spongiform encephalopathy (TSE) affecting deer.TSEs are a family of diseases thought to be caused by misfolded proteins called prions and include similar diseases such as BSE (mad cow disease) in cattle, Creutzfeldt–Jakob disease (CJD) in humans, and scrapie in sheep.

Infected cervids do this, but humans with prion disease have never been known to do so. The finding could mean that humans with CWD pass infectious prions in their fecal matter, according to Hannaoui.
Creutzfeldt–Jakob disease (CJD), also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is a fatal neurodegenerative disease. [ 4 ] [ 1 ] Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. [ 4 ]
