Prions are misfolded proteins that can induce abnormal folding of normal proteins in the brain, leading to neurodegenerative diseases. They are resistant to degradation and can propagate by converting normal proteins into the misfolded form. This process results in the accumulation of toxic aggregates, causing neuronal damage and ultimately leading to diseases such as Creutzfeldt-Jakob disease and mad cow disease. Prions challenge conventional understanding of infectious agents, as they lack nucleic acids.
