👉 Prionopidae are a family of prions, which are infectious diseases caused by prions, a group of proteins that can accumulate in the brain and other tissues over time. These proteins have been found in various organisms, including bacteria, viruses, and fungi. Prionopathies are characterized by the accumulation of these proteins within the body, leading to various neurological disorders such as Alzheimer's disease, multiple sclerosis, and progressive multifocal leukoencephalopathy (PML).
