BDNF can reverse ataxia in SCA1 mice, even after symptom onset

Written by Anna Cook Edited by Dr. David Bushart Brain-derived neurotrophic factor can prevent ataxia in SCA1 mice. New research shows that the treatment works even if it’s started after mice develop signs of ataxia. SCA1 is a neurodegenerative disease caused by a mutation in the Ataxin1 gene. People with Read More…

Four diseases, One Gene: CACNA1A

Written by Dr. Judit Pérez Edited by Dr. David Bushart A new case report describes how a new mutation in the CACNA1A gene causes ataxia with seizures. Genes and their diseases Hereditary ataxias are caused by mutations in different genes that affect how different parts of the brain and spinal Read More…

Failure to repair DNA damage may be linked to SCA3

Written by Dr. Ambika Tewari Edited by Dr. Maria do Carmo Costa Mutations in Ataxin-3 protein prevent the normal functioning of a DNA repair enzyme leading to an accumulation of errors Cells are bombarded by thousands of DNA damaging events each day from internal and external sources. Internal sources include Read More…

Clearing aggregated ataxin-2 protein as a therapeutic avenue for SCA2

Written by Dr. Vitaliy Bondar Edited by Dr. Hayley McLoughlin New research suggests that mutant ataxin-2 protein overwhelms cells in SCA2, leading to decreased autophagy and clearance of damaged proteins. Many comparisons can be made between cells and human beings. Just like humans, cells can accumulate junk and waste at Read More…

A new molecule identified that controls cerebellar communication

Written by Dr. Ambika Tewari Edited by Dr. Sriram Jayabal Targeting phosphatases in the cerebellum can correct miscommunication in multiple models of ataxia. The cerebellum is essential for motor coordination and consists of the coordinated activity of different types of cells. Purkinje cells are one of the most fascinating cell Read More…
