Our current research aims at studying human brain development and disease in conditions such as Parkinson’s disease (PD). To this end, we generate models with human induced pluripotent stem cells to investigate a) the development and evolution of human brain and b) mechanisms of neurodegeneration in familial PD.

Understanding the mechanisms underlying human brain development and disease has long been hampered by limited access to the living brain and the inability to isolate and maintain live human neurons. The advent of human stem cells in combination with cellular reprogramming technologies has opened new perspectives in the field of brain research. Human embryonic stem cells and induced pluripotent stem cells (iPSCs) generated by reprogramming of differentiated somatic cells to pluripotency, provide for the first time the opportunity to foster live human neurons and glial cells in the laboratory.

1. Patient-derived model for Parkinson’s disease pathogenesis: a platform for mechanistic studies and the identification of disease-modifying compounds

A major focus of research has been the generation of iPSCs from skin fibroblasts of patients with familial Parkinson’s disease bearing the p.A53T mutation in the α-synuclein protein (G209A in the SNCA gene) to elucidate disease mechanisms and identify new therapeutic targets. Directing their differentiation to neurons, we developed a 2-D clinically relevant model displaying distinct disease phenotypes that has been an instrumental biological system for mechanistic studies of disease pathogenesis and drug discovery (Kouroupi et al PNAS 2017; Taoufik et al Open Biol 2018; Grudina, Kouroupi et al Neurobiol Dis 2019; Elkouris, Kouroupi et al Front Cell Neurosci. 2019 ; Kouroupi et al Int J Mol Sci 2020; Int J Dev Biol. 2021; Kim… Kouroupi et al Front Microbiol. 2021; Antoniou et al npj Parkinson’s Disease 2022).

Recently, we received funding from the Hellenic Foundation for Research and Innovation to develop a research project on the contribution of astrocytes in p.A53T pathology and investigate neuron-glia dynamics in Parkinson’s disease.

2. High Content imaging and compound library screening identifies novel therapeutics for Parkinson’s disease

The p.A53T system has been adapted for high-content imaging and compound library screening, which identified the multi-kinase inhibitor BX795 as a promising neuroprotective molecule and candidate therapeutic for PD and possibly other protein conformational disorders. Proteomics profiling mapped the molecular pathways underlying the protective effects of BX795, comprising a cohort of 118 protein-mediators of the core biological processes of RNA metabolism, protein synthesis, modification and clearance, and stress response, all linked to the mTORC1 signaling hub. In agreement, expression of human p.A53T-αSyn in neuronal cells affected key components of the mTORC1 pathway resulting in aberrant protein synthesis that was restored in the presence of BX795 with concurrent facilitation of autophagy (Antoniou et al 2022 npj Parkinson’s disease). Research is ongoing to identify BX795 direct targets.

3. Uptake and transmission of pathological proteins implicated in Parkinson’s disease

We collaborate with Prof. Chiara Zurzolo from the Institut Pasteur in Paris within the framework of a Pasteur International Unit (PIU) on Neurodegenerative diseases. Within this framework and in collaboration with researchers at the Tokyo Metropolitan Institute of Medical Science we investigated the uptake and transmission of α-synuclein implicated in Parkinson’s disease pathology. Using our human p.A53T-iPSC derived model, we found that the transfer of α-synuclein fibrils is mediated primarily by a novel cell contact mechanism through tunneling nanotubes, indicating that the ability of neural cells to uptake and transfer pathological proteins may limit their effectiveness in therapeutic transplantation for treatment of neurodegenerative diseases (Grudina, Kouroupi et al Neurobiol Dis 2019).

4. In vivo modeling of p.A53T-aSyn pathology

We investigated the in vivo fate and phenotypes of patient-derived p.A53T-iPSC derived neurons after transplantation in a chemically-induced mouse model of Parkinson’s disease established by unilateral intrastriatal 6-hydroxydopamine injection in the immunosuppressed NOD/SCID strain. We found that mutant cells could survive and differentiate in vivo over a 12-week period. However, at this time point they displayed significantly increased levels of α-synuclein, signaling a first step towards pathology, and showed compromised integration within the host tissue. This data imply caution regarding the long-term consequences of autologous transplantation as a therapeutic strategy for Parkinson’s disease patients (Zygogianni et al Methods Mol Biol. 2020; Neurochem Res. 2019).

5. Development of a human stem cell-based model of human brain development: investigation of human-associated traits of neurodevelopment

An iPSC-based system has been generated for modeling human brain development in 2D cultures. Integrated mRNA/miRNA transcriptome analysis at distinct stages of directed neuronal differentiation identified miR-934, a human-associated miRNA that displays a stage-specific expression pattern during progenitor expansion and early neuron generation. We demonstrated the biological relevance of this finding by comparison with data from early to mid-gestation human cortical tissue. miR-934 directly controls progenitor to neuroblast transition and impacts on neurite growth of newborn neurons. Its inhibition results in profound global transcriptome changes associated with neurogenesis while affecting the expression of genes associated with the subplate zone, a transient compartment most prominent in primates that emerges during early corticogenesis. Our work highlights mir-934 as a novel regulator of early human neurogenesis with potential implications for a species-specific evolutionary role in brain function (Prodromidou and Matsas Cell Mol Life Sci 2021; Prodromidou et al. eLife 2020; Prodromidou and Matsas Front Cell Neurosci. 2019).

This new core facility initiative, aims to provide capacity for high-throughput high-content imaging and phenotypic screening, using cellular disease models and tissue organoids for investigation of poorly understood complex human conditions, such as neurodegenerative diseases.

Recent advances in cell reprogramming technologies have facilitated the generation of patient-derived models for neurodegenerative diseases and the identification of early, potentially triggering, pathological phenotypes while they provide amenable systems for drug discovery.

The Platform aims at combining disease-modeling, automated high-content imaging, compound library screening and multi-electrode array electrophysiological recordings for integrated morphological, molecular, cellular and functional studies.

Setting-off in relevance to neurodegenerative diseases, the platform aims to provide expertise for collaborative ventures and services to the scientific community, and expand its activities in infectious and chronic diseases.
