FFI DISEASE SKIN

They believe the abnormalities likely are features of asymptomatic FFI that may lead to disease. In the new study using the FFI organoids, NIAID scientists working at Rocky Mountain Laboratories in Hamilton, Mont., compared cell functions – primarily in neurons – between the FFI model and organoids without the FFI protein mutation, making several important observations about the mutation’s effect on brain cells. Because they can survive in a controlled environment for months to years, cerebral organoids also are ideal for studying nervous system diseases over lengthy periods of time. Cerebral organoids have organization, structure, and electrical signaling systems similar to human brain tissue.

FFI DISEASE SKIN

Human cerebral organoids are small balls of brain cells ranging in size from a poppy seed to a pea scientists use human skin cells to create organoids.

In a new study published in PLOS Genetics, scientists from the National Institute of Allergy and Infectious Diseases (NIAID) developed a cerebral organoid model to study the exact protein mutation that causes FFI. Likewise, studies in rodents and laboratory glassware only have provided limited information. But at that point, valuable disease information is not available because the brain no longer functions. Because FFI is found in the brain (suspected origin is the thalamus) studying its spread is not possible until a patient has died. Unfortunately for those with the disease, it can be hereditary – thus the “familial” aspect in the name and importance of developing diagnostic tests and treatments.įFI is among a group of unusual neurologic conditions known as prion diseases – those caused by normally harmless prion protein that can malfunction and kill brain cells. Fewer than 1,000 people in the United States are estimated to have FFI, according to the NIH’s Genetic and Rare Diseases Information Center.

Fortunately, the disease is extremely rare. A protein mutation in the brain prevents sleep, and the body gradually deteriorates.
