This project aims to investigate the underlying mechanisms of neurodegeneration caused by the accumulation of alpha-synuclein (aSyn) in Parkinson’s disease (PD), Parkinson’s disease with dementia (PDD), and dementia with Lewy bodies (DLB). This independent research project will encompass a wide range of techniques in the fields of neuroscience and immunology – from stem cells to behavioural studies – and focuses on understanding the role of innate immune responses in the onset and progression of aSyn-related neurodegeneration.
The pathological hallmarks of synucleinopathies involve aSyn accumulation and aggregation in the cytoplasm and nucleus. Early events that trigger aSyn accumulation remain elusive, but recent studies suggest that abnormal activation of innate immune responses may play a role. Building upon these findings, we hypothesize that dysregulated immune responses contribute to disease initiation and progression, ultimately leading to aSyn-related neurodegeneration.
Rotation Project Objectives:
To explore if innate immune responses are activated at the initial phase of synucleinopathy. You will investigate alterations in expression of inflammatory target genes upon accumulation of aSyn using established model systems. The underlying pathogenic pathways will be elucidated using interaction studies.
Year 1: Training in Drosophila, cell culture and gene-editing. To study the effects of immune-related target genes on synucleinopathy using Drosophila and cell culture.
Year 2: Determine the role of immune signalling in established cell and animal models of aSyn proteinopathy.
Year 3: Continue objectives from year 2 while evaluating rare genetic variants in co-factors that regulate immunity using proteomics.
These studies will identify how innate immunity drives synucleinopathy and discover potential therapeutic candidates that can be clinically assessed for the treatment of these devastating, currently incurable diseases.
