Prion diseases (also referred to as transmissible spongiform encephalopathies, or TSEs) are a group of progressive, untreatable, and fatal neurodegenerative conditions affecting both humans and animals. Generally, these conditions are characterized by long incubation periods (usually between 5 to 20 years), disruption in the normal tissue structure (resulting in holes and vacuole formation in the neurons), and the absence of an inflammatory response.

Evolution of ancient cellular components paves a path to parasitic adaptations in Apicomplexan parasites.
Proteins undergo many kinds of post translational modifications (PTMs), such as phosphorylation, ubiquitination, SUMOylation, geranyl-geranylation, farnesylation, myristoylation, acetylation, succinylation and palmitoylation. PTMs can be reversible or irreversible, they can be dynamic or stable. PTMs enable fine tuning of protein function in response to various internal and external signals and therefore they have profound effects on cellular physiology, metabolism, survival and growth.
