Abstract Spinocerebellar ataxia 13 (SCA13) is an autosomal dominant neurological disorder caused by mutations in KCNC3. Our previous studies revealed that KCNC3 mutation R423H results in an early-onset form of SCA13. Previous biological models of SCA13 include zebrafish and Drosophila but no mammalian systems. More recently, mouse models with KCNC3 mutations presented behavioral abnormalities but without obvious pathological changes in the cerebellum, a hallmark of patients with SCA13.

Abstract Background: Futile recanalization affects more than half of acute ischemic stroke (AIS) patients. Neutrophil extracellular traps (NETs) are a major factor of microvascular hypoperfusion after stroke. Deoxyribonuclease I (DNase) targeting NETs exhibited a neuroprotective effect in young mice with AIS. This study explored a novel direct intra-arterial administration of DNase therapy and its effect in aged mice with AIS.

Abstract Background: Neuroinflammation is a recognized pathological characteristic of neurodegenerative diseases. Spinocerebellar ataxia 13 (SCA13) is a progressive neurodegenerative disease with no effective treatments. Our previous studies reported human mutations in KCNC3 gene are causative for SCA13. Human R423H allelic mutation induces early-onset neurodegeneration and aberrant intracellular retention of Epidermal Growth Factor Receptor (EGFR) in drosophila.
