Prions are misfolded proteins that, when they enter the brain, can convert normal proteins into their misfolded forms. This can lead to a build-up of abnormal proteins, causing damage to nerve cells and ultimately leading to neurodegenerative diseases such as Creutzfeldt-Jakob disease.

What pathogen causes CJD?
Creutzfeldt-Jakob disease (CJD) is caused by abnormal prion proteins that affect the brain's structure and function. It is not caused by a traditional pathogen like a virus or bacteria.
Can prions affect a prion?
Yes, prions can interact with and convert other normal proteins into misfolded prion proteins, propagating the disease process. This conversion leads to the accumulation of abnormal prions in the brain, causing neurodegenerative diseases such as Creutzfeldt-Jakob disease.
What is caused by a prion making holes in the brain?
A prion making holes in the brain can cause a group of rare neurodegenerative disorders known as prion diseases, such as Creutzfeldt-Jakob disease. This leads to a spongiform appearance in the brain tissue due to the formation of microscopic holes. Symptoms include cognitive decline, personality changes, and movement disorders.
What is the pathogen that causes Mad Cow Disease?
A prion, or misfolded protein caused by genetic mutation.

Is mad cow disease an example of a prion?
Bovine Spongiform Encephalopathy, also known as BSE, or Mad Cow Disease, is an exact example of a proteinaceous infectious particle, or Prion. It is an infectious molecule composed primarily of protien, unlike viruses. BSE attacks the brain, it is a neurodegenerative disease causing a break down of the brain tissue and spinal cord.
What does the Pathogen of Creutzfeldt-Jakob disease look like?
What we know so far is that the "pathogen" is not alive. It is a protein, which we called it prion. It does not have DNA or RNA. It comprised of amino acids only. It causes problems by entering the host and change the shape of the good proteins in the brain. Then the immune cells in the brain try to eat up (engulf) these prion protein but at the same time kill the brain cells. As a result, the brain become a sponge.
Does prions cause Alzheimers?
No, prions do not cause Alzheimer's disease. Alzheimer's is characterized by the accumulation of beta-amyloid plaques and tau protein tangles in the brain, while prion diseases, such as Creutzfeldt-Jakob disease, are caused by misfolded prion proteins that lead to brain damage and cell death through a different mechanism.
What Biological agent that is an infective chemical?

When was Antarctic Prion created?
Antarctic Prion was created in 1789.
When was Fairy Prion created?
Fairy Prion was created in 1820.
