Dr. Edward Fon, MD, FRCP(C) is a neurologist-scientist at the Montreal Neurological Institute-Hospital (The Neuro) specializing in movement disorders and a Professor in the Department of Neurology and Neurosurgery at McGill University. He is the Director of the FRQS Quebec Parkinson Network and the Scientific Director of The Neuro. He was trained at the Université de Montréal, McGill University and the University of California, San Francisco (UCSF). His research focuses on the molecular and cellular events leading to Parkinson's disease (PD). His laboratory has made contributions to understanding the function and cell biology of PD genes and in understanding how defects in these genes lead to PD. In particular, his lab has focused on understanding the function of Parkin, PINK1, α-synuclein, GBA, LRRK2, TMEM175 and DJ1, and has established the infrastructure at The Neuro to study these genes and pathways in human patient-derived induced pluripotent stem cells (iPSCs), which are differentiated into neurons, glia and 3D brain organoids. The lab is currently using these iPSC systems to establish a pipeline to better understand the role of lesser-studied PD genes, identified in recent genome-wide association studies (GWAS), in PD pathogenesis. In addition, Dr. Fon helped establish the Tanenbaum Open Science Institute (TOSI) at The Neuro and oversees its platforms including the Clinical Biological Imaging and Genetic repository (C-BIGr) and iPSC/CRISPR Early Drug Discovery Unit (EDDU).

My research focuses on the effect induced by toxic accumulation of protein aggregates essentially composed of the protein Alpha-Synuclein. These aggregates are tought to be involved in neuronal decay in the brains of patients with Parkinson's disease, leading to loss of cognition and death. We do not know the genetic actors contributing to this neuronal toxicity. In order to identify and validate new target genes for the development of new therapeutic treatments, I combine the increased growth and division ability of cultured cell lines and the physiological relevance of a dopaminergic neuron model generated from induced pluripotent stem cells from healthy individuals and Parkinson's patients. The goal of my project is to reduce or prevent this toxicity and excessive neuronal death characteristic of Parkinson's disease.

My research aims at deciphering some of the molecular and structural basis of mitochondrial-quality control pathways in mammalian cells. Specifically, I am interested in understanding the molecular dialogue between protein quality-control and mitochondrial import machinery. In addition, I am interested in delineating the molecular basis of protein degradation roles in cellular demise in the context of PD.

Variants of the GBA1 gene encoding the lysosomal enzyme glucocerebrosidase are one of the most common risk factors for Parkinson’s Disease (PD). In addition, mutations in other lysosomal proteins have recently been linked to increased risk and earlier age at onset in GBA1-associated PD, suggesting an important role for lysosomal proteins in developing the disease. My projects in the lab use cellular models including dopaminergic neurons and microglia derived from human iPSC to characterize the roles of these lysosomal protein in the context of PD, and to understand the molecular mechanisms behind greater susceptibility to disease conferred by patient’s mutations. Shedding light on these mechanisms is key to finding relevant targets and improving the treatment of PD.

I study the role of LRRK2 and Rab GTPases in the pathogenesis of Parkinson's disease by using induced pluripotent stem cell (iPSC) based models. I focus particularly on understanding the role of LRRK2-Rab signaling in iPSC derived microglia, and co-culturing microglia and neurons in 3 dimensions. My goal is to unravel the mechanisms underlying LRRK2-Rab communication and neuroinflammation in Parkinson's disease.

My research focuses on characterizing neural activity present in human derived midbrain organoids as a model of Parkinson’s disease (PD). Organoids are a promising tool that can be used to study neurodegenerative diseases on a patient specific level. There is evidence showing that organoids exhibit certain aspects of disease pathology such as the inclusion of protein aggregates and neuronal death, complementary to what we see occur in human models of PD. However, there is extensive literature showing that PD also causes abnormal activity in basal ganglia circuits, namely increased bursting activity and synchronization between basal ganglia nuclei. My aim is to determine whether midbrain organoids can accurately model the changes in neural activity associated with PD. To do this, I will conduct an in-depth analysis of electrophysiological properties, pathological markers, and pharmacological testing on PD patient-derived hMOs and their isogenic controls. My goal is to validate the reliability of using organoids as a model to study neurodegenerative diseases in a patient specific manner.

My project is focused on the biochemical profiling of α-synuclein aggregates from various cellular models of Parkinson’s disease (PD). α-synuclein aggregation is a pathological hallmark of a group of diseases known as synucleinopathies. Recent research has shown α-synuclein forms different fibrils capable of adopting self-perpetuating conformations, known as strains, which may characterize distinct clinical synucleinopathy syndromes. This could explain why and how α-synuclein aggregates can be present in various Parkinsonian diseases and yet lead to different patterns of disease progression and cellular damage. Leveraging the advantages of patient-derived 3D midbrain organoids, my goal is to develop a bioassay for the detection and characterization of pathological α-synuclein aggregates and to screen for patient-specific therapeutics.

 My research at the Fon lab focuses on the effect of novel genes on α-synuclein aggregate propagation in Parkinson’s Disease. The spread of α-synuclein throughout the central nervous system is believed to be one of the main contributors to the progressive nature of the disease. Particularly, I am interested in the mechanisms involved in the uptake and accumulation of α-synuclein aggregates in neurons. In my research, I utilize CRISPR activation and interference to study the effect of specific gene modulation on the accumulation of lab-generated α-synuclein preformed fibrils in cells. My goal is to elucidate the mechanisms of α-synuclein uptake and accumulation in iPSC-derived neurons, and uncover possible therapeutic targets for the treatment of Parkinson’s disease.

I work with researchers to determine appropriate equipment for experiments and to develop experimental designs to address specific research questions. This includes consultation on image processing and analysis and the development of automatized analytic tools through imageJ macros, for instance. I finally do regular maintenance of the microscopy equipment and initiate repairs if necessary.

My research interest lies in better understanding the role of GWAS-associated PD genes and characterize the lesser-studied PD genes in genetically-modified induced pluripotent stem cell derived midbrain organoids. With the use of PD phenotypic assays and unbiased multi-omics, we hope to disentangle the PD GWAS-ome by uncovering new pathways or mechanisms in PD pathology and new key targets for therapy
