Probing disorders of the nervous system using reprogramming approaches

Probing disorders of the nervous system using reprogramming approaches. Justin K Ichida, Evangelos Kiskinis, The EMBO Journal (2015) embj.201591267 DOI 10.15252/embj.201591267

Perhaps the seemingly biggest advantage of this approach—the ability to study disease in the genetic background of the patient—has created the biggest challenge, as genetic background contributes to high variability in the properties of the patient‐derived cells. This variability is a reality that neurologists have been facing for years, as often, two patients diagnosed with the same condition might present with very different clinical profiles. The technology of cellular reprogramming has brought this reality of clinical heterogeneity seen in patients from the bedside to the lab bench.

Open-label Pilot Study of Methylprednisolone for the Treatment of Patients With Friedreich Ataxia (FRDA)

Open-label Pilot Study of Methylprednisolone for the Treatment of Patients With Friedreich Ataxia (FRDA). Sponsor: Children's Hospital of Philadelphia, Collaborator: Friedreich's Ataxia Research Alliance. First received: April 16, 2015

This study will explore whether methylprednisolone treatment is safe, well-tolerated, and beneficial in patients that are diagnosed with Friedreich Ataxia (FRDA). The study will also explore if methylprednisolone has any effects on biomarkers associated with FRDA. All subjects in the study will receive the same steroid treatment.
This study will take place at the Children's Hospital of Philadelphia as an outpatient trial in 5 children who are at least 5 years and less than 10 years of age, and in 5 adults ages 45 years and older, with genetically confirmed FRDA.

Effect of mental fatigue on speed-accuracy trade-off

Effect of mental fatigue on speed-accuracy trade-off. Vianney Rozand, Florent Lebon, Charalambos Papaxanthis, Romuald Lepers, Neuroscience, Available online 4 April 2015, ISSN 0306-4522, http://dx.doi.org/10.1016/j.neuroscience.2015.03.066.

Previous studies suggested that the speed-accuracy trade-off is altered in specific cases, e.g., the patients with Friedreich ataxia that alter motor coordination but not cognitive functions (Corben et al., 2011) or the elderly (Sleimen-Malkoun et al., 2013). In these populations, movement duration was slowed compared to healthy young subjects, especially for higher difficulties.

Autophagy in neurodegenerative diseases: from pathogenic dysfunction to therapeutic modulation

Autophagy in neurodegenerative diseases: from pathogenic dysfunction to therapeutic modulation. Marta Martinez-Vicente, Seminars in Cell & Developmental Biology, Available online 2 April 2015, ISSN 1084-9521, http://dx.doi.org/10.1016/j.semcdb.2015.03.005.

Autophagic dysfunction has been described in many neurodegenerative diseases, ranging from Alzheimer’s disease (AD), to Parkinson’s disease (PD), Huntington’s disease (HD), amyotrophic lateral sclerosis (ALS), Friedreich's ataxia and others. Failure of the autophagic process may thus be one of the factors contributing to neuronal cell death
