Prions do not contain a nucleic acid genome. J.S. Griffith first proposed the protein-only theory in 1967 to explain how prions could replicate if they were made of protein but did not contain ...

Prions, the protein family notorious for causing "mad cow" and neurodegenerative diseases like Parkinson's, can play an important role in healthy cells.

But growing evidence suggests that prions are at play in many, if not all, neurodegenerative disorders, including Alzheimer's, Huntington's and Parkinson's, also marked by aggregations of ...

Prions, mysterious shape-shifting proteins, can lead to brain disorders such as Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy, "mad cow disease" in cattle, yet they can ...

Prions are best described as misfolded proteins with an ability to transmit their misfolded shape onto normal variants of the same protein. Let's dive into the many fatal neurodegenerative ...

Prions made in the lab Date: January 4, 2016 Source: Sissa Medialab Summary: At times, to understand something well, it is useful to rebuild it from scratch.

Prions are not rare, usually are not harmful and may even help organisms adapt, a new study in yeast suggests. Prions are shape-shifting proteins that change function along with their shapes, and ...

But sometimes, prions can also be transmitted from one individual to another (infamously, the prion disease kuru was spread through cannibalism), or even between two different species of animal.

Prions, the infectious agents responsible for transmissible spongiform encephalopathies, consist mainly of the misfolded prion protein (PrPSc). The unique mechanism of transmission and the appearan ...

The researchers detected prions in the eyes of all 11 patients. What's more, they found prions in all eight regions of the eye that were tested, including the eye's cornea, lens, ...
