MECANISMO DE DOENÇA

Spinocerebellar ataxia 1

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. SCA1 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. SCA1 is caused by expansion of a CAG repeat in the coding region of ATXN1. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.

Neural basis for mutant ATAXIN-1 induced respiratory dysfunction in mouse models of spinocerebellar ataxia type 1.

Neurobiology of disease2026 Mar 17

Spinocerebellar ataxia type 1 is a neurodegenerative disease characterized by motor dysfunction and premature death usually from compromised swallowing and respiration. Using plethysmography, we characterized respiration in the conditional f-ATXN1146Q/2Q SCA1 model. We found a progressive elevation of baseline respiration that impairs ability of f-ATXN1146Q/2Q mice to increase breathing during challenge. To delineate regions contributing to respiratory dysfunction, f-ATXN1146Q/2Q mice were crossed with Nestin-Cre and Acta1-Cre mice, respectively. Respiration improved by removing mATXN1 from neural lineages, but not from skeletal muscle demonstrating mATXN1 in the central nervous system is a key driver of respiratory dysfunction in SCA1 mouse models. Moreover, respiratory dysfunction in SCA1 mice involves two aspects: behavioral dysregulation exhibited as increased movement during plethysmography, and functional dysregulation of respiratory circuitry. As both of these aspects are rescued by deleting mATXN1 from neural cells, we further investigated the role of cerebellar Purkinje cells and chemosensing neurons in the brain stem in SCA1 respiratory phenotype. Our results indicate complex multiregional etiology of respiratory dysfunction. Mechanistically we found that in contrast to most other SCA1 symptoms, nuclear localization of mATXN1 does not play a key role in respiratory dysfunction.

Mutant ATXN1 impacts human and mouse microglia and contributes to cognitive, mood, and motor deficits in SCA1 mice.

bioRxiv : the preprint server for biology2026 Feb 17

Microglia, resident immune cells of the brain, are important players in neurodegeneration. While microglial activation is a hallmark of many neurodegenerative diseases, the specific role of microglia intrinsic factors in microglial activation and disease pathogenesis remains unknown. Spinocerebellar ataxia type-1 (SCA1) is an inherited autosomal dominant neurodegenerative disease characterized by severe neuronal loss and early microglial activation in the cerebellum. SCA1 is caused by CAG repeat expansion in the ubiquitously expressed ATAXIN1 (ATXN1) gene. Using human microglia differentiated from SCA1 patient derived iPSCs, we found that mutant ATXN1 is sufficient to alter morphology, gene and protein expression in human microglia in a cell-autonomous manner. Moreover, compared to controls, human SCA1 microglia exhibited increased phagocytosis and pro-inflammatory cytokine production, indicating an immune priming. To determine the extent to which mutant ATXN1 in microglia contributes to SCA1 pathogenesis and behavioral symptoms, we removed mutant ATXN1 from microglia and macrophages in a novel conditional SCA1 mouse model, f-ATXN1146Q/2Q mice. Microglial mutant ATXN1 reduction led to a marked correction in microglia phenotype, in particular in the transcriptomic signature of interferon type 1 mediated immune response, reduced microglial density and resulted in smaller microglia with reduced branching in the cerebellum. Pathology of Purkinje neurons and cerebellar astrogliosis were also ameliorated. Utilizing a battery of behavioral tests, we found that microglia and macrophage mutant ATXN1 reduction ameliorated cognitive, mood, and motor deficits in SCA1 mice. Together, these results indicate that mutant ATXN1 directly impacts microglial phenotype in SCA1, contributing to SCA1 pathology and behavioral deficits.

Impedance-based phenotypic profiling of metabotropic glutamate receptor ligand responses in SCA1 human iPSC-derived neuronal cultures.

Neurobiology of disease2026 Mar

Group 1 metabotropic glutamate receptors (mGluRs) are a family of G protein-coupled receptors (GPCRs) including mGluR1 and mGluR5. These receptors are expressed throughout the central nervous system and play an important role in synaptic plasticity. Dysfunction of mGluR1 in cerebellar Purkinje cells (PC) is observed in spinocerebellar ataxia type 1 (SCA1), an autosomal dominant neurodegenerative disorder caused by an expanded CAG repeat in the ATXN1 gene. MGluR1 dysfunction disrupts PC signaling and ultimately contributes to PC death and overall progressive cerebellar dysfunction observed in SCA1. To investigate mGluR1/5 pharmacology in the context of SCA1, mGluR1/5 function was assessed in SCA1 and control human induced pluripotent stem cell (hiPS)cell-derived neuronal cultures using impedance measurements in the xCELLigence real-time cell analyzer (RTCA) system. Culture conditions and protocols for evaluating glutamate receptor activity were first optimized. Subsequently, GRM1 and GRM5 expression levels were assessed and glutamatergic signaling function was characterized in SCA1 hiPS cell-derived neuronal cultures using both the non-selective endogenous ligand L-glutamate and the selective orthosteric agonist for mGluR1/5, (RS)-3,5-Dihydroxyphenylglycine. To specifically characterize mGluR1 function, mGluR1-specific positive- and negative allosteric modulators (Ro0711401 and JNJ16259685 respectively) were tested. Results showed reduced mGluR1 and decreased mGluR5 RNA expression levels and diminished mGluR1/5 responses in the SCA1 hiPS cell-derived neuronal cultures. These results underline the potential utility of impedance measurements for characterizing GPCR function and pharmacological testing in a high-throughput manner in patient-derived neuronal cultures.

Retinal morphology in spinocerebellar ataxia type 1 (SCA1) mice: A stereological analysis across different age groups.

Experimental eye research2026 Apr

Spinocerebellar ataxia type 1 (SCA1) affects not only the cerebellum but also the retina; however, retinal pathology remains poorly characterised in murine models of SCA1. To fill this gap, we performed a comprehensive stereological analysis of the retinal structure of SCA1154Q/2Q knock-in mice and their healthy SCA12Q/2Q littermates at 6 and 10 months of age. We compared animals across genotypes at each age and across ages within each genotype. Using unbiased stereology, we quantified the total retinal volume, volumes of individual retinal layers, total photoreceptor numbers, numbers of rods and cones, and total cell numbers in the inner nuclear and ganglion cell layers. Structural abnormalities, including disorganisation of photoreceptor outer segments and reduced volumes of both photoreceptor inner and outer segments, were evident in SCA1 mice as early as 6 months. By 10 months, these alterations had progressed, with a decrease in the number of ganglion cells and a reduced proportion of cones among the total photoreceptors. Wild-type mice also exhibited age-related changes, but the pattern and magnitude differed, suggesting distinct mechanisms of normal ageing versus SCA1-related neurodegeneration. Our findings demonstrate that retinal remodelling in SCA1 mice parallels changes observed in human patients, validating this model for investigating visual system involvement in SCA1. These results emphasize the need to consider retinal pathology when interpreting behavioural or motor deficits and in designing future preclinical interventions.

TMEM206 gene knockout improves balance performance in SCA1 transgenic mice.

IBRO neuroscience reports2025 Dec

TMEM206 was identified as a conserved chloride channel that underlies widely expressed, proton-activated, outwardly rectifying chloride currents. Spinocerebellar ataxia type 1 (SCA1) is one of polyglutamine diseases, and is characterized as a progressive and autosomal dominant genetic disease, which is caused by an increasing number of CAG repeats in the ataxin-1 gene. TMEM206 was confirmed to interact with ataxin-1. This study suggests that TMEM206-ataxin-1 interaction might involve in the pathological mechanisms of SCA1. To elucidate the mechanisms of SCA1 involved in proton-activated chloride channel gating, we bred TMEM206 knockout mice using SCA1 model mice. Motor coordination and balance in mice was evaluated using rotarod test and grip strength. These studies showed that genetic depletion of TMEM206 has slight impacts on the SCA1 mice weight, and partially improves motor incoordination in Atxn1154Q/2Q mice. No alteration in grip strength was found in Atxn1154Q/2Q mice with depletion of the TMEM206 gene. Our studies indicate that the TMEM206 knockout appears to emerge as a potential therapy method for SCA1 mice.
