How do prions cause other proteins to misfold
WebCertain proteins can occasionally misfold into infectious aggregates called prions. Once formed, these aggregates grow by attracting the soluble form of that protein to join them. WebPrions propagate by transmitting a misfolded protein state. When a prion enters a healthy organism, it induces existing, properly folded proteins to convert into the disease …

WebFeb 14, 2024 · Prion proteins are mostly found in the brain. The abnormal folding of prion proteins leads to brain damage and symptoms of neurodegenerative disease. A similar cycle of neuronal protein misfolding and clumping is observed in other neurodegenerative disorders, including Parkinson’s and Alzheimer’s diseases. WebPrions can somehow cause other proteins to change their shape and become prions themselves. Our bodies have defenses against some prions, but some are similar enough in shape to a good protein that they go basically undetected. That means they accumulate in your body over time, because your body has no real means of removing them.
