Improving knowledge management and data sustainability
ELIXIR Luxembourg Node, a data hub for Translational Medicine (ELIXIR-LU) |
ELIXIR, the European infrastructure for life science information, aims to provide long-term access to bioinformatics tools and biological data. ELIXIR-LU, the national ELIXIR node, focuses on long-term sustainability of tools and data for translational medicine, the combination between the clinical and experimental environment. On the national level, support in standardising and electronic capture of clinical data is provided together with hosting and analysis pipelines. Internationally, translational medicine data is hosted by the Bioinformatics Core and support is given in the curation and standardisation of data sets to improve the reusability and value of the data for the research community.

European platform for neurodegenerative disorders (EPND) |
Alzheimer’s disease (AD) and Parkinson’s disease (PD) are among the most common neurodegenerative conditions. They pose a major societal burden, because treatments that slow down these diseases are lacking. Treatment development is impeded by lack of biomarkers that can detect individuals early in the disease, measure treatment effects, and stratify patients.

Beyond 1+Million Genomes (B1MG) |
It can take less than one day to sequence a whole human genome. This technical prowess, unthinkable just a few decades ago, has opened up new possibilities for improving human health, from preventative medicine (based on genetic predisposition) and faster and more accurate diagnosis, to the development of pharmacogenomics (more efficient treatments with reduced harmful side effects). Unleashing the potential of personalised medicine, a healthcare approach that takes into account a person’s genetic make-up, is expected to bring significant socio-economic benefits, including more efficient national health systems, leading to better health and quality of life of patients, and increased life expectancy. This is, however, uncharted territory where common mechanisms to securely share the required information have yet to be designed, agreed and implemented, at national, European and international levels, so that genomic and phenotypic (clinical, lifestyle) data can be searched and accessed, within and across national jurisdictions. Europe is uniquely placed to take on this challenge and position itself as a global leader in this field..

Develop the organisation, connectivity and impact of ELIXIR Nodes to align Europe’s infrastructure roadmaps for long-term FAIR life science data (ELIXIR-CONVERGE) |
Long-term sustainability of a distributed research infrastructure rests on a foundation of stable national Nodes. ELIXIR’s long-term sustainability plan sets out a range of actions to secure operations and provide the scientific capabilities needed to support cutting-edge research. Several components of our long-term sustainability plan are already on-going and *this project* is designed to drive significant progress against the major, complex and outstanding issue of aligning national data management practice, impact assessments and national roadmap positioning. Thus, the focus of *This project* is on strengthening the national ELIXIR Nodes. *this project* will harmonise toolkits, operations and monitoring indicators. The long-term operation of a pan-European network that delivers national and transnational data management requires the development of business models, funding strategies and service agreements that ensure long-term operations of national Nodes. Specifically we aim to achieve this transformation by delivering results against four project objectives:

Citizen-centred EU-eHR exchange for personalised health (Smart4Health) |
Smart4Health will enable the citizen-centred EU EHR exchange for personalised health. This will pave the way for the full deployment of citizen-centred solutions and services in a digital single market for wellbeing and healthcare. It will provide for interoperability, complementarity and cooperativity with profiles that are currently used e.g. by Member States and regions. Smart4Health will enable the bridging between the diverse EU EHR data and citizen-generated health data. It will connect citizens to science and personalised health services. The European Commission 2017 review of the Digital Single Market lists three priorities:
Smart4Health addresses these priorities with an outstanding consortium that develops, tests and validates a platform prototype for the Smart4Health citizen-centred health record EU-EHR exchange. Smart4Health provides an easy-to-use, secure, constantly accessible and portable health data and services prototype, thus advancing citizen health and wellbeing, and digital health innovation. Smart4Health builds on the strength of the European infrastructures CEF, ELIXIR, the EIT Health, BBMRI-ERIC, the European Virtual Laboratory for Enterprise Interoperability (I-VLab), the experience and knowledge gained and generated, the EU/US collaboration in eHealth, e.g. the Icahn School of Medicine at Mount Sinai, the momentum of initiatives in the Member States, e.g. 'Medizininformatik Initiative' of the BMBF in Germany. Smart4Health enables citizens to manage and bridge their own health data throughout the EU and beyond, advancing own and societal health and wellbeing.

FAIRification of IMI and EFPIA data (FAIRplus) |
Wide sharing of knowledge and data drives the progression of science. Shared data allows other researchers to reproduce findings and benchmark quality of experiments. Sharing data so that other researchers can Find, Access and Interoperate – i.e. integrate the data with the outcomes of their own experiments - allows Reuse and an opportunity to build the large aggregated cohorts we need to detect rare signals and manage the many confounding factors in translational research. This project will develop the guidelines and tools needed to make data FAIR. Through worked examples using IMI and EFPIA data and application and extension of existing methods we will improve the level of discovery, accessibility, interoperability and reusability of selected IMI and EFPIA data. In addition, through disseminated guidelines and tailored training for data handlers in academia, SMEs and pharmaceuticals, data management culture will change and be sustained and datasets will be reused by pharmaceutical companies, academia and SMEs. Our FAIR SME & Innovation programme will enable wide data reuse and foster an innovation ecosystem around these data that power future re-use, knowledge generation, and societal benefit. We call this approach ‘FAIRplus’. Funding body: Innovative Medicines Initiative (IMI-JU) Coordinator: Serena Scollen, ELIXIR-Europe, United Kingdom Official website: https://fairplus-project.eu |
Data integration across disease and disciplines
Diagnostic test to improve surveillance and care of COVID-19 patients (COVIRNA) |
Coronavirus disease 2019 (COVID-19) caused by infection with SARS coronavirus 2 (SARS-CoV-2) has reached pandemic proportions with more than 7 million people infected and 0.4 million people killed worldwide. Death rates are accentuated by cardiovascular comorbidities and arrhythmias leading to unexpected major cardiovascular events. Being able to identify COVID-19 patients at risk of developing cardiovascular events leading to death would allow improving surveillance and care. Currently, there is no accurate method to predict outcome of COVID-19 patients. COVIRNA is a patient-centered Innovation Action aiming to satisfy this urgent and unmet need. COVIRNA will complete and deploy a prognostic system based on cardiovascular biomarkers of COVID-19 clinical outcomes combined with digital tools and artificial intelligence analytics (i.e. prediction model). Complementary expertise of 15 EU partners from the healthcare sector, academia, association and industry will allow conducting a large retrospective study on existing cohorts of COVID-19 patients. By upscaling the already validated and patented research use only FIMICS panel of cardiac-enriched long noncoding RNA biomarkers into an in-vitro diagnostic test (COVIRNA) adapted to COVID-19 patients, the project will quickly deliver a minimally-invasive, simple yet robust and affordable prognosis tool that can be used in the context of the current COVID-19 crisis as well as in further major health issues. By tackling the cardiovascular complications in COVID-19, known to contribute significantly to mortality, the project outputs are expected to have a major impact on the pandemic outcomes. The COVIRNA test will be CE-marked and prepared for commercialisation, allowing to risk stratify patients, adapt therapies and to inform drug design.

Exascale Centre of Excellence in Personalised Medicine (PerMedCoE) |
This HPC centre of excellence optimises codes for cell-level simulations in HPC/Exascale and bridges the gap between organ and molecular simulations, thus contributing to the European Personalised Medicine Roadmap. The centre will become the entry point to Exascale-ready cell-level simulation software, able to transform personal omics data into actionable mechanistic models of medical relevance, supporting developers and end-users with know-how and best practices. It will connect simulation software developers with HPC, HTC and HPDA experts at centres of excellence such as POP and HiDALGO. PerMedCoE will also work with other biomedical consortia such as ELIXIR and LifeTime, connecting pre-exascale infrastructures hosted by supercomputing centres such as the Barcelona Supercomputing Center and CSC–IT Center for Science. The LCSB is one of the 12 partners from across Europe participating in this project. The Bioinformatics Core is in charge of developing and optimising a pre exascale cell level simulation software and leads the development of guidelines for data protection and privacy preservation in an exascale HPC environment.

Identification of personalised inflammatory profiles of aging and senescence which are modified specifically by risk factors of dementia modulating the pre-dementia speed of symptomatic progression (PREADAPT) |
Age represents by far the highest risk factor for dementia, including Alzheimer’s disease (AD). However, not every person will develop dementia during aging, indicating that age-related processes may not inescapably lead to dementia. The elucidation of the fundamental processes occurring in aging is likely to prevent or postpone the development of dementia. One such key mechanism is cellular senescence, which causes chronic inflammation through the release senescence-associated secretory phenotype (SASP) profile of mediators. PREADAPT will build on the hypothesis that chronic systemic- and neuroinflammation, quantified through a set of SASP mediators, affects the basal trajectory of the senescence occurring in the aging brain, thus allowing to predict future cognitive decline and dementia. The levels and changes of SASP mediators during aging are modulated by different genetic and environmental factors defining thereby a personalised risk for progressing to dementia. Importantly, research has identified that SASP mediators are also altered in cerebrospinal fluid of AD patients. Moreover, SASP together with genetics, known AD biomarkers, and other comorbidities define a combined Risk Profile which provides personalised information on the risk of progressing to dementia. To achieve these goals, PREADAPT has gathered a team of leading experts in the field of neuroinflammation, epidemiology, genetics, epigenetics, neuropsychology, and clinical research. PREADAPT has access to state-of-the-art methodology and knowhow on inflammatory markers to define a set of SASP mediators which derived from PREADAPT own preliminary research. PREADAPT has also access to large epidemiological and clinical follow-up studies that are characterised in-depth using neuroimaging, genomics, and proteomics. This unique configuration will enable PREADAPT to identify, already at pre-dementia stages, age-related profiles informing on the personalised future risk to decline cognitively and to progress to dementia. From a translational perspective, PREADAPT will provide first evidence showing that a SASP personalised risk profile responds to specific intervention depending on the profile of an individuum.

moleculaR -based, Data -driven drug REpurposing for bladder Cancer (ReDiRECt) |
ReDiRECt targets to introduce in the pharmaceutical company sector (the market) candidates for drug repurposing in bladder cancer (BC) (the products). An in silico drug repurposing based on the comparison of the molecular signature of BC against the molecular signature of drugs will be applied. The BC signature will be derived from integration of proteomics data with publicly available transcriptomics and literature- mined data. The most promising findings will be tested in model systems.

HeartMed: an ICT platform combining preclinical and clinical information for enhancing translational medicine and patient specific modelling in cardiovascular diseases (HeartMed) |
Heart failure, the number 1 reason for death in the EU, is a disease with complex aetiology (e.g. volume dependent heart failure, ischemic heart disease, hypertension, etc. ) and varying severity (HFpEF, HFrEF). As these influencing factors vary between patients, individual treatment options are urgently needed. This heterogeneity also often prevents the transfer of mono-causal animal models to humans as the shared and disliked features are unknown. The availability of bio-medical data on individual patients (imaging, sensors, omics) has increased dramatically in recent years and deep-phenomapping has the potential to better classify patients based on heterogeneous data sets. Furthermore, mechanistic models have matured to clinical application enabling molecular understanding of complex pathophysiological processes if data quality is sufficient. Here we propose a novel concept (the HeartMed platform) to enhance translational medicine and support personalised medical decision making. HeartMed will compile heterogeneous data of animal models and human patients and perform deep-phenomapping to identify heart failure subclasses and assess conformities and differences between pre- and clinical phenotypes. For patient specific modelling models have to be parameterised with data of sufficient high quality, that are difficult and expensive to obtain from patients (e.g. omics from myocardial tissue). This results in so called “missing data”. Based on the phenomapping classification, HeartMed will combine pre-/clinical information for complementing missing data to enable patient specific mechanistic modelling for a broader class of patients. In a Clinical proof-of-concept study of patients with heart failure (retrospective data), we will use the HeartMed platform to improve patient classification, determine transferability of animal models and use animal data to improve patient specific modelling with metabolic and hemodynamic models.

Better control and treatment of immune-mediated diseases by exploring the universe of microenvironment imposed tissue signatures and their correlates in liquid biopsies (ImmUniverse) |
Immune-mediated diseases (IMIDs) are an increasing medical burden in industrialised countries worldwide. IMIDs are characterised by an enormous heterogeneity with regard to disease outcome and response to targeted therapies, which currently cannot be adequately anticipated to tailor individual patient management. Hence, mechanistic understanding of this heterogeneity and biomarkers predictive for disease control and therapy response over time are important prerequisites of a future precision medicine in IMIDs. ImmUniverse has been formed as a European transdisciplinary consortium to tackle these unmet needs and to understand the role of the crosstalk between tissue microenvironment and immune cells in disease progression and response to therapy of four different IMIDs: ulcerative colitis, Crohn’s disease, Psoriasis and atopic dermatitis. Following this unique cross-disease approach ImmUniverse will fill the gap and the limitations of current studies, which do not systematically compare the complex interactions between recirculating immune cells and the respective tissue microenvironment. The consortium will combine analysis of tissue-derived signatures with “circulating signatures” detectable in liquid biopsies, employing state-of-the-art profiling technologies corresponding to multi-Omics datasets. The project will also bring diagnostics in IMID to a new level by implementing disruptive non-invasive liquid-biopsy methodology in combination with novel, validated circulating biomarker assays which are expected to improve diagnosis, inform early in the clinical course on disease severity and progression and enable treatment response monitoring. The identified signature will be validated to monitor state/progression and response to therapy in prospective observational cohorts. Realisation of these objectives will result in improvement of patient management, lead to increased patient well-being and will significantly reduce the socioeconomic burden of these diseases.

Immune Safety Avatar: nonclinical mimicking of the immune system effects of immunomodulatory therapies (imSAVAR) |
The vision of Immune Safety Avatar (imSAVAR) is to develop a platform for integrated nonclinical assessments of immunomodulatory therapy safety and efficacy. Existing nonclinical models do not adequately represent the complexity of the immune system and its interactions in both immunoncology and immunmediated diseases. They also do not accurately reflect the diversity of response to new therapies that is seen in clinical medicine. We will, thus, constantly refine existing and develop new nonclinical models with the final goal of validation aiming at:
The platform imSAVAR will be based upon case studies for prioritised therapeutic modalities and has been built around institutes of the Fraunhofer-Gesellschaft which has strong track records in applied science and in particular toxicology. The consortium will improve the prediction of the transferability of safety and efficacy of immunomodulators from pre-clinical models to first-in-human studies in collaboration with the private sector, pharma, regulators and technology providers. We will share experience on customised models that can be deployed (w.r.t. the 3Rs principles), establish the necessary infrastructure, conduct the analyses and provide wider disease domain expertise. This conjoint effort assures that the platform imSAVAR constantly benefits the field of immune safety evaluation, and will generate opportunities for European businesses. A guiding principle of this consortium is the meaningful engagement of multiple stakeholders including patients and regulators.

Multi-omics Interdisciplinary Research Integration to Address DEmentia diagnosis (MIRIADE) |
Dementia is currently diagnosed largely based on cognitive decline, while pathology starts years before symptom onset. To make progress in the development of effective drugs for dementia, there is an urgent need for biomarkers to enable precision health: for early and specific diagnosis and objective monitoring of disease progression.

Biomarkers in Atopic Dermatitis and Psoriasis (BIOMAP) |
Our objective is to provide a taxonomic and predictive systems medicine model of Atopic Dermatitis and Psoriasis based on clinical and molecular profiling to (i) identify determinants of clinically relevant outcomes (disease manifestation, progression, comorbidity development and treatment response) (ii) improve understanding on shared and distinct disease mechanism(s) and associated signatures, and their relative importance in patient subpopulations and (iii) deliver biomarkers that identify disease trajectories and treatment response for use in drug development and clinical practice. BIOMAP will create a biospecimen and data resource of unprecedented scale and depth accessible via a central, open-source data and analysis portal, harmonising diverse, high quality, multi-dimensional datasets on skin and blood (whole and single cell), large scale population-based and trial data alongside clinical research infrastructure delivering supplementary material flexible to the needs of the consortium. This resource will be systematically analysed using state-of-the-art methodologies in epidemiology, molecular profiling, skin biology and mathematical modelling to define disease and drug endotypes and how these interact with lifestyle and environmental factors. Selected, highly discriminatory, associated biomarkers will pass through a diagnostics pipeline (novel in-silico trial methods and assay development), ready for immediate translation. BIOMAP is expected to drive drug discovery to target causal mechanisms, shorten drug development pathways, and fundamentally change the diagnosis and management paradigm, from re-active to pro-active strategies that encompass disease biology and life-time trajectory, matching the intervention (prevention, modification of risk factors, therapeutics) with endotypes. Clinically annotated endotypes and associated biomarkers will identify when, in whom and how to intervene to minimise disease impact and improve outcomes.

Exploiting GLIOblastoma intractability to address European research TRAINing needs in translational brain tumour research, cancer systems medicine and integrative multi-omics (GLIOTRAIN) |
Glioblastoma (GBM) is the most frequent, aggressive and lethal of all brain tumours. It has a universally fatal prognosis with 85% of patients dying within two years. New treatment options and effective precision medicine therapies are urgently required. This can only be achieved by focused multi-sectoral industry-academia collaborations in newly emerging, innovative research disciplines. GLIOTRAIN will exploit the intractability of GBM to address European applied biomedical research training needs. The ETN, which comprises 9 beneficiaries and 14 partner organisations from 8 countries, will train 15 innovative, creative and entrepreneurial ESRs. The research objective of GLIOTRAIN is to identify novel therapeutic strategies for application in GBM, while implementing state of the art next generation sequencing, systems medicine and integrative multi-omics to unravel disease resistance mechanisms. Research activities incorporate applied systems medicine, integrative multi-omics leveraging state of the art platform technologies, and translational cancer biology implementing the latest clinically relevant models. The consortium brings together leading European and international academics, clinicians, private sector and not-for-profit partners across GBM fields of tumour biology, multi-omics, drug development, clinical research, bioinformatics, computational modelling and systems biology. Thus, GLIOTRAIN will address currently unmet translational research and clinical needs in the GBM field by interrogating innovative therapeutic strategies and improving the mechanistic understanding of disease resistance. The GLIOTRAIN ETN addresses current needs in academia and the private sector for researchers that have been trained in an environment that spans translational research, medicine and computational biology, and that can navigate confidently between clinical, academic and private sector environments to progress applied research findings towards improved patient outcomes.

A Systems medicine approach to chronic inflammatory disease (SYSCID) |
The SYSCID consortium aims to develop a systems medicine approach for disease prediction in CID. We will focus on three major CID indications with distinct characteristics, yet a large overlap of their molecular risk map: inflammatory bowel disease, systemic lupus erythematodes and rheumatoid arthritis. We have joined 15 partners from major cohorts and initiatives in Europe (e.g.IHEC, ICGC, TwinsUK and Meta-HIT) to investigate human data sets on three major levels of resolution: whole blood signatures, signatures from purified immune cell types (with a focus on CD14 and CD4/CD8) and selected single cell level analyses. Principle data layers will comprise SNP variome, methylome, transcriptome and gut microbiome. SYSCID employs a dedicated data management infrastructure, strong algorithmic development groups (including an SME for exploitation of innovative software tools for data deconvolution) and will validate results in independent retrospective and prospective clinical cohorts. Using this setup we will focus on three fundamental aims : (i) the identification of shared and unique "core disease signatures” which are associated with the disease state and independent of temporal variation, (ii) the generation of "predictive models of disease outcome"- builds on previous work that pathways/biomarkers for disease outcome are distinct from initial disease risk and may be shared across diseases to guide therapy decisions on an individual patient basis, (iii) "reprogramming disease"- will identify and target temporally stable epigenetic alterations in macrophages and lymphocytes in epigenome editing approaches as biological validation and potential novel therapeutic tool. Thus, SYSCID will foster the development of solid biomarkers and models as stratification in future long-term systems medicine clinical trials but also investigate new causative therapies by editing the epigenome code in specific immune cells, e.g. to alleviate macrophage polarisation defects.

National Centre of Excellence in Research: Early diagnosis and stratification of Parkinson’s Disease (NCER-PD) |
NCER-PD represents a joint effort between 4 partners in Luxembourg that unite their expertise in Parkinson’s disease. In order to answer the urgent questions surrounding the occurance of Parkinson’s disease, researchers need to analyse clinical data and samples from hundreds of patients and healthy control persons. Our group provides NCER-PD with our competences and technology for the integration, curation and analysis of multidimensional data. To this end, the Data and Computation platform will establish secure and anonymised data ows among other NCER-PD platforms. Well-grounded machine learning and computational modeling approaches will enable data analysis and interpretation.

Using Whole Genome Sequencing data from LRRK2 families to identify novel rare variants of LRRK2 associated Parkinson's disease |
The age of onset and penetrance (likelihood of disease) of individuals with the LRRK2 G2019S mutation varies considerably, the latter ranging in some families from as high as 100 percent to as low as 22 percent. This variation suggests that genetic modifiers contribute to LRRK2 pathogenesis in Parkinson’s disease (PD). The objective of this project is to collect and sequence the genomes of multiple LRRK2 families and use innovative technology and computational approaches to identify and validate novel genetic modifiers of LRRK2-mediated neurodegeneration. The overarching goal is to identify genetic modifiers of LRRK2 G2019S–induced neurodegeneration in PD. To do this, researchers propose a four phase plan:
This project hopes to identify genes that are important for the progression of LRRK2 associated PD. By sequencing the genomes of individuals from many families harboring LRRK2 mutations, investigators will use computational approaches to pinpoint specific genetic mutations that either enhance or lessen the onset and/or progression of LRRK2-associated PD. They will then use neurons, derived from patients with LRRK2 mutations, to validate and understand the role of these genetic mutations within cells. This work would not only increase understanding of what goes wrong in the cells of LRRK2 patients, but also help with genetic testing and in identifying potential therapeutic targets.

Epi25 Collaborative for Large-Scale Whole Genome Sequencing in Epilepsy (Epi25 Collaborative) |
Epi25 is a collaborative of more than 200 partners from 40 research cohorts from around the world. More than 14,000 exomes have been sequenced as part of this collaborative effort. We expect to find evidence that accurate and detailed phenotypic data reduces genetic heterogeneity, allows for identification of a well-matched replication cohort, and clarifies the phenotypic spectrum associated with a gene. This approach will help us address fundamental questions about the importance of rare variants, common variants, or de novo changes as the basis for specific forms of epilepsy.

Epileptogenesis of genetic epilepsies (FOR 2715) |
Epilepsy is a common, severe, and disabling condition with a significant disease burden worldwide. Despite many available treatment options, the seizures are not well controlled in one third of all patients with epilepsy. Gene discovery and first functional analyses of genetic defects have been major drivers to unravel disease mechanisms in the last 20 years and have brought about the first personalised treatment options. However, most of the genetic alterations underlying epilepsy remain to be elucidated and the mechanisms driving a healthy into an epileptic brain are not well understood. A common feature of genetic epilepsies is the typical age dependency the origin of which is largely unknown and which differs between syndromes. Therefore, developmental factors are likely to play a pivotal role for epileptogenesis of genetic epilepsies. In this Research Unit (RU), we aim to investigate if and how genetic mutations induce a cascade of multidimensional epileptogenic processes, such as transcriptional, cellular (morphological, neurophysiological), and network changes, and how these interact with developmental processes which likely contribute to the age‐dependent manifestation of seizure and behavioral phenotypes in genetic epilepsies.

Mitochondrial Risk factors in Parkinson's Disease (MiRisk-PD) |
Mitochondria play an essential role in neuronal function and survival. Maintaining the functional integrity of mitochondria is important for cell survival. Extensive prior data generated by use of genotyping arrays and/or exome sequencing approaches in monogenetic and sporadic forms of PD has unequivocally implicated mitochondrial dysfunction as one of the central pathophysiological pathways in PD. Nevertheless, there remains an appreciable gap in deciphering the missing heritability in PD. Primarily, this may result from a dominating focus on understanding the impact of common and rare variants encoded by nuclear genes in PD. By contrast, emerging evidence suggests that genetic variability within mitochondrial DNA may explain missing heritability which, hitherto, cannot be deciphered by nuclear encoded genes alone. This hypothesis is supported by various genetic studies which have shown the involvement of mitochondrial “haplogroups” in causing disease susceptibility for PD. However, results have remained inconclusive so far due to inadequate sample sizes. In the proposed project, MiRisk-PD, we will implement an integrative approach to understand the role and impact of both nuclear encoded mitochondrial genes and the mitochondrial genome in explaining the missing heritability in PD. This new integrative strategy will be based on (i) a large exome repository of clinically well-defined PD cohort (4500 cases and 5500 controls) within Parkinson disease Genomics Sequencing Consortium (PDGSC) to define nuclear encoded “mitochondrial-network map”; (ii) a unique collection of families with autosomal dominant and autosomal recessive PD (for mitochondrial genome sequencing) and (iii) a large cohort of clinically well-defined sporadic PD patients (45,000 cases and 40,000 controls) from the Genetic Epidemiology of Parkinson disease (GEoPD) consortium, covering different populations worldwide for genetic studies that will translate into (iv) functional validation studies in patient-derived cellular models. The multisystem approach, as outlined in our MiRisk-PD proposal, will identify stratified cohorts based on the genomic profile to identify and explore novel therapeutic targets, paving the way for a personalised medicine program for PD.

New Therapies for Neurological Ion Channel and Transporter Disorders (Treat-ION) |
Treat-ION represents a network of clinicians and scientists across Germany to advance the knowledge about recognising and treating rare neurological ion channel and transporter disorders. Those comprise a variety of neuropsychiatric diseases and symptoms including developmental delay, epilepsy, episodic and chronic ataxia, migraine and others, which often occur in combination or are caused by mutations in the same channels. Due to the common fundamental function of channels and transporters to regulate neuronal excitability and ionic homeostasis, pathophysiological and therapeutic principles are shared across diseases. The main goal of this grant application is to translate findings from genetic and pathophysio- logical studies into rational, individualised therapies. We will therefore focus on therapeutic studies in cellular, animal and human models, which will be complemented by in silico searches for new treatments, better predictions for the functional consequences of mutations for therapeutic purposes and cellular drug screens. We will focus our efforts on approved and available ‘repurposed’ drugs. As a proof-of-principle, we successfully have been per- forming n-of-1 trials and established three investigator-initiated trials in specific rare channel disorders with other funding, which will be of great value for the network. The results of our research and the knowledge of experts will be systematically and directly delivered to patients through a structured molecular therapeutic board attached to the German academy of rare neurological diseases (DASNE).
