Prions

Scientific discoveries shake the trust of scientists and make it question whether they truly understand the fundamental laws of nature. This is exactly what Prion is doing to understand scientists' understanding of the basic rules of infection. Prions cause disease, but they are not viruses, bacteria, fungi or parasites. They are just proteins and are not considered infectious. This organism is infectious and protein is not. Or at least they have never done such a thing.

Prion disease is a group of neurodegenerative diseases caused by prions, "protein infectious particles". For some background, the first thing to see is the introduction of prions. Prion diseases are caused by prion proteins in misfolded form, also known as PrP. In addition to humans, these diseases affect many different mammals - for example, sheep have scrapie, cows have mad cow disease, and deer has chronic wasting disease. Human-type prion diseases are usually caused by Creutzfeldt-Jakob disease (CJD), fatal familial insomnia (FFI), Geltmann-Straussler-Scheinker syndrome (GSS), rickets disease and variable protease susceptible prion diseases (VPSPr) Since all of these diseases are caused by slightly different versions of the same protein, we call them all prion diseases.

Infectious protein acting like virus but without DNA. Prion is an infection because misfolded versions of prion protein can misfold fold the normal form of prion protein to spread the disease. Incorrectly folded proteins will not function correctly. The normal prion protein spreads throughout the life-kingdom and plays an important role. Proteins are composed of amino acid chains and are large molecules with various functions indispensable for the life of organisms. Depending on the composition of the protein, the protein acts as an antibody in the immune system, or it helps signal transduction between cells and internal organs in the body. DNA is the genetic code of the cell, and it is a design drawing of all the proteins in the cell.

The causative substance of TSE is considered to be prion. The term "prion" refers to an abnormal virulence factor which is transmissible and is capable of inducing abnormal folding of certain normal cellular proteins known as prion proteins, which are most abundantly present in the brain. The function of these normal prion proteins is not yet completely understood. Abnormal folding of prion proteins results in characteristic signs and symptoms of brain injury and disease. Prion disease is usually rapid and fatal
