Targeting Astrocyte Brain Cells That Turn Toxic Could Help Treat Huntington’s, Other Diseases

A subtype of brain cells called astrocytes could be contributing to the death of neurons in neurodegenerative diseases such as Huntington’s disease (HD), according to a new study published in the leading scientific journal Nature. This new finding presented in a report titled “Neurotoxic reactive astrocytes are induced by activated microglia” is important because it provides opportunities for scientists to develop new treatment approaches to treat Huntington’s and other neurodegenerative diseases.

Protein May Prevent Neuron Death in Huntington’s Patients, Study Finds

A protein called Nrf2 can help maintain healthy levels of proteins associated with neurodegenerative diseases, including Huntington’s disease, thereby protecting neurons from death, according to new research. Results of the study, “Nrf2 Mitigates LRRK2- And α-synuclein–induced Neurodegeneration By Modulating Proteostasis,” were published in the journal PNAS. Neurodegenerative disorders…

Judgment Task, Called Reversal Learning, Diminishes as Huntington’s Advances, Study Suggests

The ability to apply reversal learning, which involves adapting behavior according to changes in stimulus-reward situations, appears to be diminished in patients with Huntington’s disease and to worsen as the disease progresses, according to new research. This study, “Reversal Learning Reveals Cognitive Deficits And Altered Prediction Error Encoding In The Ventral Striatum…

Numerous DNA Repeats Seen in Huntington’s May be Result of Gene Repair Effort

Researchers may finally have tracked down an explanation for expansions of three-letter DNA sequences that disrupt genes, and lead to Huntington’s disease and numerous other neuromuscular and neurodegenerative conditions. The study, “The role of break-induced replication in large-scale expansions of (CAG)n/(CTG)n repeats,” published in the journal Nature Structural & Molecular…
