Prions: Definition, Structure, Function, Disease, Prevention, Control, Treatment, Transmission.
What is Prions? Prion is an abnormal or misfolded protein that causes fatal disease in animals and humans by transmitting
Prions are abnormal proteins that are believed to be responsible for several rare, degenerative brain disorders in animals and humans. These disorders, known as transmissible spongiform encephalopathies (TSEs), include mad cow disease in cows, scrapie in sheep, and Creutzfeldt-Jakob disease (CJD) in humans.
Prions are unusual in that they are infectious agents that do not contain nucleic acid, the genetic material found in all living organisms. Instead, they are thought to be composed solely of proteins. Prions are believed to cause TSEs by altering the shape and function of normal proteins in the brain. This leads to the accumulation of abnormal, proteinaceous aggregates in the brain, which can cause damage to brain tissue and lead to the symptoms of TSEs.
Prions are difficult to detect and eliminate, and there is currently no cure for TSEs. However, research into the biology of prions and TSEs is ongoing, and scientists are working to develop treatments and prevention strategies for these disorders.
TSEs are characterized by the accumulation of abnormal, proteinaceous aggregates in the brain, which can cause damage to brain tissue and lead to the symptoms of the disease.
Here are some examples of TSEs caused by prions:
Overall, TSEs caused by prions are rare but serious diseases that can lead to significant brain damage and death. There is currently no cure for TSEs, and research into these diseases is ongoing.
