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…

Continuous low oxygen reverses motor symptoms in FA mice

Continuous exposure to low levels of oxygen, or hypoxia, prevented or rapidly reversed motor symptoms in a mouse model of Friedreich’s ataxia, a study suggested. While a continuous mild hypoxia regimen also slowed the onset of motor symptoms, it didn’t reverse motor impairment. Intermittent hypoxia had a detrimental effect…
