3 FA mouse models fail to accurately capture cardiomyopathy, study finds

Three mouse models of Friedreich’s ataxia (FA) do not accurately reflect FA-associated cardiomyopathy — a serious heart complication — as seen in patients, underscoring the difficulties in modeling this complication, a study reports. Across these different models, only one exhibited gene activity changes in the heart consistent with cardiomyopathy…

International Ataxia Awareness Day hopes to spur conversations

Sparking conversations about ataxia — a group of disorders that include Friedreich’s ataxia believed to affect 26 of every 100,000 children globally — will be the chief aim of this year’s annual International Ataxia Awareness Day (IAAD), set for Sept. 25. The 23-year-old event is organized by the…

New mouse model better mimics FA features in humans: Study

Researchers have developed a new mouse model of Friedreich’s ataxia (FA) that captures coordination and muscle strength impairment seen in patients, a study reports. The model was created by worsening symptoms of a standard mouse model by further suppressing production of the frataxin protein, which is deficient in FA…

Interferon gamma helps protect cells from damage in disease model

Treatment with interferon gamma (IFN-gamma), an immune signaling molecule, helped to protect against damage in a cellular model of Friedreich’s ataxia (FA), a study reports. Although IFN-gamma failed to show clear benefits in clinical trials, these new findings “could help in the design of better therapeutic schedules and shed…

MRI detects brain changes in early Friedreich’s ataxia

MRI scans detect large- and small-scale changes in various areas of the brain and brainstem in the early stages of Friedreich’s ataxia (FA) over time, a new study reports. Many of the changes occurred outside the cerebellum, a brain region primarily implicated in the motor problems associated with…
