Bill Nye is back in his lab with NAF and Biogen—breaking down the science of Friedreich Ataxia in a new video series. WATCH NOW
Written by Katerina Pliatsika Edited by Hannah K Shorrock, PhD Additional proteins which interact with ATXN1 contribute to toxicity in a SCA1 mouse model. In neurodegenerative diseases, a problematic gene and its resulting protein play a crucial role in the selective loss of brain cells. However, a fundamental question remains unanswered: Read More…
BDNF stands for Brain-derived neurotrophic factor. BDNF is a protein found in the brain that belongs to the group of neurotrophic proteins. Neurotrophic means that these proteins promote the survival and growth of new neurons during brain development and the survival and function of existing neurons in the adult brain. Read More…
Written by Alexandra Putka Edited by Dr. Pragya Goel Feeling tired? You’re not alone. Fatigue is a common symptom of Spinocerebellar ataxias and affects quality of life. Spinocerebellar ataxias (SCAs) are characterized by various symptoms, but fatigue is not often included on this list. Fatigue is clinically defined as difficulty Read More…
Written by Christina PengEdited by Larissa Nitschke, PhD Ever since the CAG expansion of the Ataxin-1 (ATXN1) gene has been identified as the cause of spinocerebellar ataxia type 1 (SCA1), researchers have been on the hunt for the mechanism of the disease. How does this mutation cause SCA1? So far, Read More…
Written by Marija Cvetanovic, PhDEdited by Spyros Petrakis, PhD Researchers from Yale provide evidence that glial cells, in particular Bergmann glia in the cerebellum, may contribute to disease pathogenesis in SCA1. The human brain contains approximately 170 billion cells. However, approximately half of them (86 billion cells) are not neurons. Read More…
Written by Alexandra Putka Edited by Dr Hannah K Shorrock Scientists characterize SCA1, 2, 3, & 6 disease progression, finding that symptoms change most rapidly in the first 10 years of the disease. Designing clinical trials for rare diseases such as spinocerebellar ataxias (SCAs) requires us to know the timeline Read More…
Escrito por Dr. Gülin ÖzEditado por Dr. Celeste SuartTraduzido por Ana Carolina Martins A ressonância magnética (RM) detecta alterações cerebrais antes dos sintomas de ataxia. A lista de empresas farmacêuticas que direcionaram a sua atenção para as ataxias tem aumentado ao longo da última década. Isto se deve ao promissor Read More…
Written by Tala Ortiz Edited by Dr. Larissa Nitschke Repeat-associated non-AUG (RAN) translation in CAG repeat expansion diseases is toxic to cells and causes them to die. The Jain group found that RAN proteins and expanded RNA can be found in the same location in cells and interfere with essential Read More…
Written by Rana Abdelhalim Edited by Dr. Spyros Petrakis Early BDNF delivery improved cognitive and motor deficits while ameliorating cerebellar pathology in a SCA1 mouse model. Cognitive impairment, slurred speech, difficulty with balance and walking— these are all symptoms of spinocerebellar ataxia type 1 (SCA1). SCA1 is an inherited neurodegenerative Read More…
Oligodendrocytes are a type of brain cell that play a crucial role in insulating neurons to facilitate efficient transmission of electrical signals. Similar to the rubber coating on cords, oligodendrocytes wrap around axons with a cholesterol-rich myelin structure, which speeds up the transmission of electrical impulses. Each oligodendrocyte can myelinate Read More…
