Brain network-based determination of genes that clear mutant huntingtin fibrils

Huntington disease (HD) is caused by a CAG trinucleotide repeat expansion within the huntingtin (HTT) gene which produces a mutant HTT (mHTT) protein. This mHTT protein aggregates within neurons, forming fibrils that interfere with cellular functions and result in neurodegeneration. The spatiotemporal dynamics of HD pathogenesis is a complex interplay between mHTT production, spread, and likely clearance: fibrils spread from cell-to-cell in prion-like and concentration-dependent manners, and initial seeding of fibrils is preferentially seen in certain cell types (striatal medium spiny neurons). Furthermore, evidence from other disorders (Parkinson's) indicate the presence of neuroprotective genes (e.g. GBA) that clear pathogenic proteins. In HD, clearance genes remain an area of active investigation.

Beyond Exon 1: Exploring the Pathogenic Role of Novel Huntingtin Aggregates in vivo.

Mutations within exon 1 of the huntingtin (HTT) protein promote its aggregation and accumulation in the brain and periphery, ultimately driving neuronal dysfunction and the clinical manifestation of Huntington’s disease (HD). Although HTT is a large protein composed of more than 3,000 amino acids, exon 1 represents less than 3% of its total length. For decades, this small N-terminal fragment has been viewed as the principal driver of pathology. Yet HTT is far more than exon 1, and regions outside this domain can also undergo proteolytic processing, potentially generating toxic species whose contribution to disease remains poorly understood.

Investigating Trans-acting Genetic Modifier Variants’ Association with Loss of Interruption (LOI) Variants and Impacts on Age of Onset in Relation to Canonical Alleles.

Huntington’s disease (HD) age of onset is primarily determined by the CAG repeat length in the huntingtin gene (HTT); however, CAG repeat length does not fully explain the variability in age of onset observed between HD affected individuals. Approximately a dozen HD genetic modifiers have been identified through genome-wide association studies (GWAS) that alter the onset and severity of disease to varying degrees.

Centre for Neurotechnological Innovation to Application

The Centre for Neurotechnological Innovation to Application (CRANIA) transforms routine neurosurgical procedures into valuable research opportunities to advance brain science and treatment. Currently, when patients undergo procedures like deep brain stimulation for Parkinson's disease or surgery for epilepsy, the unique brain data captured during these interventions often remains isolated in specialized hospitals, limiting scientific discovery.

WONDER: A Data Platform for AI-Enabled Precision Health in Childhood Disability

Brain-based disabilities, such as autism, ADHD, cerebral palsy, and rare genetic conditions, affect one in five children and often lead to lifelong challenges. These conditions are complex and vary widely from child to child, making it difficult to find treatments that work for everyone. Despite years of research, we still lack the tools to understand this diversity and provide personalized care. To address this, we propose WONDER (Whole-Child Open Neuroscience Data for Empowering Research), a new national research platform that will securely connect and analyze data from across Canada.

Enabling Neuroscience research Approaches for Brain, feeLings and Emotions (ENABLE): An Innovative Platform for Clinical Trials in Mood Disorders

Depression and bipolar disorder, known as mood disorders, significantly impact the lives of many Canadians, especially women and the LGBTQ+ community. Although many treatments are available, it is often challenging for clinicians to determine which treatment is the right one for a particular individual.

NeuroAccess: The Canadian Platform for Human Nervous Tissue Research

Chronic pain affects millions of Canadians and is one of the leading causes of disability worldwide. Neurological and psychiatric conditions more broadly represent an immense burden, affecting one in three people and costing billions each year. Yet progress in developing new treatments has been slow.

PRIME-RNA: A platform for in vivo preclinical testing of RNA therapeutics

RNA medicines—short strands of nucleic acids that can turn genes “up” or “down”—have changed how we treat brain diseases. For example, nusinersen for spinal muscular atrophy and tofersen for ALS are given by spinal injection to reach the brain and spinal cord. These breakthroughs show that RNA drugs work in the nervous system. However, before these treatments can reach patients, they must be tested in living systems to ensure safety and effectiveness.
