MECANISMO DE DOENÇA

Spinocerebellar ataxia 3

Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to cerebellum degeneration with variable involvement of the brainstem and spinal cord. SCA3 belongs to the autosomal dominant cerebellar ataxias type I (ADCA I) which are characterized by cerebellar ataxia in combination with additional clinical features like optic atrophy, ophthalmoplegia, bulbar and extrapyramidal signs, peripheral neuropathy and dementia. The molecular defect in SCA3 is the a CAG repeat expansion in ATX3 coding region. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.

Gastrodin inhibits the formation of ataxin-3 aggregates by regulating the level of ERK1/2/P38 proteins.

Orphanet journal of rare diseases2026 Feb 19

Spinocerebellar ataxia type 3 (SCA3/Machado-Joseph disease), an incurable autosomal dominant neurodegenerative disorder, is caused by cytotoxic aggregation of polyglutamine-expanded ataxin-3 protein. Novel therapeutic strategies targeting its pathogenesis are urgently needed. Given gastrodin’s established antioxidative and neuroprotective properties, this study investigated its therapeutic potential against SCA3 pathogenesis. Three distinct cell models including parental HEK293T, ataxin-3-15Q (physiologic), and ataxin-3-77Q (pathogenic) were employed to assess gastrodin cytotoxicity, quantify insoluble aggregate formation and measure soluble ataxin-3 levels. Mechanistic studies included antioxidant capacity assays, human phosphokinase array profiling (37 kinases) and western blot validation of MAPK pathway components. Gastrodin treatment showed no cytotoxicity, significantly suppressed ataxin-3-77Q aggregate accumulation (p < 0.01), increased soluble ataxin-3 levels, enhanced cellular antioxidant capacity and selectively downregulated ERK1/2 and p38 proteins in MAPK pathways. We provide first evidence that gastrodin mitigates polyQ-mediated proteotoxicity by reducing ataxin-3 aggregation through suppression of the ERK1/2-p38 signaling axis in cellular models, revealing a novel mechanistic basis for SCA3 therapeutic development. The online version contains supplementary material available at 10.1186/s13023-025-04089-1. Gastrodin’s safety profile was demonstrated in SCA3 cellular models at concentrations up to 100 µM without causing cytotoxicity. Gastrodin significantly reduced the formation of polyQ-expanded ataxin-3 aggregates. There was a dose-dependent increase in soluble ataxin-3 levels by gastrodin. Gastrodin was found to attenuate SCA3 proteotoxicity in cellular models by simultaneously decreasing the total protein levels of ERK1/2 and p38.

Peripheral and autonomic nervous system involvement in spinocerebellar ataxia type 3: unveiling an invisible burden.

Journal of neurology2026 Jan 07

Neuropathological examinations in spinocerebellar ataxia type 3 (SCA3) have demonstrated peripheral and autonomic nervous system degeneration, but the impact of associated symptoms on genetically affected individuals at different disease stages remains understudied. To investigate the clinical burden of peripheral and autonomic nervous system involvement in SCA3 mutation carriers across the disease spectrum. Forty SCA3 mutation carriers, including ten pre-ataxic individuals, completed questionnaires about muscle cramps, neuropathic pain, autonomic symptoms, activities of daily living, and quality of life, and underwent a standardized clinical examination of ataxia and neuropathy severity. Data were compared with 16 healthy controls. All but one of the ataxic and 60% of pre-ataxic individuals experienced muscle cramps at least weekly. Neuropathic pain was reported by 20% of pre-ataxic and 16.7% of ataxic mutation carriers, while the average number of autonomic symptoms in both groups was 2 and 4.7, respectively. Neuropathy severity scores were significantly higher in pre-ataxic and ataxic individuals than in healthy controls and associated with (i) worse self-reported functional status and (ii) clinician-reported ataxia severity. The number of autonomic symptoms was associated with patient-reported impairments in daily life and quality of life. Clinical features of peripheral and autonomic nervous system degeneration are very common in SCA3, may already be observed in pre-ataxic individuals, and independently contribute to patient-reported disease burden and clinician-rated overall ataxia severity.

Extracellular vesicles-associated AAVs for the treatment of Machado-Joseph disease.

Molecular therapy : the journal of the American Society of Gene Therapy2026 Jan 07

Machado-Joseph disease (MJD) is the most common dominant autosomal inherited ataxia worldwide, caused by the overrepetition of the trinucleotide CAG in the ATXN3 gene. This leads to the accumulation of mutant ataxin-3 protein and neurodegeneration. Currently, treatment remains symptomatic, although gene therapy has emerged as a promising approach. However, efficient and minimally invasive gene delivery to the brain remains a challenge. Extracellular vesicle-associated adeno-associated virus (EV-AAV) vectors are a novel delivery system, combining the ability of AAV vectors to deliver genes with the capacity of extracellular vesicles to bypass the immune system and cross the blood-brain barrier (BBB). Previous studies, however, have only combined AAV serotypes known to efficiently cross the BBB with EVs as a non-invasive delivery system to the brain. Thus, the ability of EV-AAVs to cross the BBB remained inconclusive. In this study, we evaluated whether AAV1/2 serotype, combined with rabies virus glycoprotein (RVg)-coated EVs, could effectively target the brain. Two isolation methods, differential ultracentrifugation and size-exclusion chromatography (SEC) were compared, with SEC yielding higher EV recovery. Moreover, RVg-EV-AAV1/2 successfully crossed the BBB and transduced mouse brains, leading to motor and neuropathologic improvements in an MJD mouse model. This study demonstrates that RVg-EV-AAVs are promising non-invasive delivery systems for MJD gene therapy.

Cognitive impairment in SCA3: A multi-center cohort study with demographic, imaging, and biomarker correlates.

Neurobiology of disease2026 Mar

Cognitive deficits are common in spinocerebellar ataxia type 3 (SCA3), but their neurobiological correlates remain largely unknown. To investigate cognitive performance in a large international cohort of SCA3 mutation carriers covering the entire disease course and to explore associations with posterior cerebellar volumes, basal ganglia and thalamus volumes, and plasma neurofilament light chain (NfL) concentration. The Montreal Cognitive Assessment (MoCA) was used to evaluate cognitive impairment in this prospective, observational cohort study involving 13 ataxia referral centers. Standardized motor assessments, brain MR imaging, and peripheral blood biosampling were also performed. MoCA data were collected from 61 pre-ataxic SCA3 mutation carriers, 231 ataxic SCA3 patients, and 111 healthy controls. After adjustments for educational level and age, there were significant differences in MoCA total score, as well as visuospatial/executive, attention, language, and abstraction subscores, between healthy controls and ataxic, but not pre-ataxic individuals. MoCA scores declined with ataxia severity, especially in patients with a lower educational level. Patients with a MoCA score < 26 had lower pallidal volumes and higher plasma NfL concentrations than those with a score ≥ 26. However, only the interaction term between ataxia severity and educational level was independently associated with cognitive performance in multivariable regression analyses containing demographic, clinical, volumetric, and biochemical parameters. Cognitive deficits in SCA3 generally appear after clinical ataxia onset and progress in parallel with ataxia severity, especially in patients with a lower cognitive reserve. Other measured biochemical and imaging parameters did not have a significant additional contribution.

Brain atrophy staging in spinocerebellar ataxia type 3 for clinical prognosis and trial enrichment.

EBioMedicine2026 Jan

Spinocerebellar ataxia type 3 (SCA3) is characterised by progressive brain atrophy, with regional volume loss detectable via MRI prior to clinical manifestation. We aimed to identify the previously unknown sequence of brain atrophy in SCA3 and evaluate whether this sequence can be translated into an atrophy staging framework to enable accurate clinical prognosis and trial enrichment. We included data from 322 SCA3 mutation carriers, enrolled in observational studies conducted across Europe, the Americas, and Asia. Participants underwent follow-up assessments up to five years after baseline. The Subtype and Stage Inference machine learning algorithm was applied to estimate the most likely atrophy sequence(s) from baseline anatomical MRI. The Scale for the Assessment and Rating of Ataxia (SARA) was used to capture ataxia severity. Atrophy stages were analysed in relation to SARA and time from disease onset. Interventional trials were simulated to estimate required sample sizes under different atrophy stage eligibility criteria. We identified a uniform sequence of brain atrophy in SCA3, characterised by earliest volumetric decline in the caudal brainstem and substantial involvement of the white matter. Atrophy stage was associated with both SARA and time from disease onset. Atrophy staging outperformed single-region volumetrics in predicting SARA over time. Applying atrophy stage cut-offs substantially reduced the sample sizes needed to adequately power hypothetical clinical trials. These findings yield mechanistic insights into the progression of neurodegeneration in SCA3 and possess immediate translational relevance, facilitating patient stratification and sample enrichment for interventional trials.
