DELEIDI LAB

"MITOCHONDRIA & INFLAMMATION IN NEURODEGENERATIVE DISEASES"

Overview of Our Research

The Deleidi Lab "Mitochondria & Inflammation in Neurodegenerative Diseases" is a research lab at the German Center for Neurodegenerative Disease (Tübingen). The lab was founded in 2016 in the framework of the Helmholtz Young Investigator Group program. Research in our laboratory concentrates on the molecular mechanisms of neurodegeneration, with a special emphasis on Parkinson's disease.

 

RESEARCH

Our research aims at studying how discrete genetic factors contribute to the development of neurological disorders, with a particular focus on Parkinson's disease (PD). To this end, we develop models with human pluripotent stem cells and long-term cultures of organoids combined with single cell-omics to identify the role of disease related genetic variants and validate targets with diagnostic and therapeutic potential.

THE INNATE IMMUNE SYSTEM IN NEURODEGENERATIVE DISEASES

Several genetic clues link inflammation to neurodegenerative diseases. With this respect, it is interesting to note that many disease-linked genes (in AD, ALS and PD) are highly expressed in a variety of immune cells. However, it remains unclear whether and how these variants promote inflammatory responses that influence actual disease risk. Our recent research has focused on the non-cell autonomous role of PD related genes; to investigate inflammatory and metabolic changes, we combine in vivo models with transgenic mice and in vitro systems, including patient blood cells as well as myeloid precursors and microglia differentiated from human iPSCs.

LYSOSOMAL BIOLOGY OF PARKINSON'S DISEASE

Lysosomal storage diseases (LSDs) are a group of rare, inherited, metabolic disorders caused by the deficiency of various lysosomal enzymes and the accumulation of their substrates. Most affect the brain, with variable manifestations, from mild adult-onset symptoms to severe neurodegeneration causing premature death. Interestingly, LSDs share pathological features with common neurodegenerative diseases. Thus, models of these rare conditions could greatly contribute to an enhanced understanding of more common neurodegenerative disorders, including PD and AD. Our research  aims at investigating the risk/resilience factors of neuronopathic LSDs combining iPSC 2/3D models with single cell -omics.

INFECTIONS, CHRONIC INFLAMMATORY DISEASES, AND NEURODEGENERATION

Certain mutations that modulate the risk for infections also contribute to an increased predisposition for developing neurodegenerative diseases. In the framework of this project, we are investigating how specific disease-related genetic traits can confer both susceptibility to infection and predisposition to neurodegeneration. The major goal of our research is to unravel unique and shared molecular pathways underlying inflammatory, infectious, and neurodegenerative diseases. To this end, we employ  in vivo modeling, stem cell-derived organoids, and functional genomic approaches.

MICHELA DELEIDI

Principle Investigator

Michela Deleidi has a strong background in neuroscience, immunology, and stem cell biology. She completed her studies in Medicine and clinical residency in Neurology at Vita-Salute University, San Raffaele Hospital (Milan, Italy). Afterwards, she worked at Harvard Medical School where she focused on the molecular mechanisms of neurodegeneration in Parkinson's disease (PD) and the use of induced pluripotent stem cells (iPSCs) for disease modeling and regenerative medicine applications. In 2011 she was awarded a research fellowship by the Alexander von Humboldt Foundation to conduct her doctoral studies at the Department of Parkinson Genetic at the University of Tübingen. During these years, she worked on the link between lysosomal storage diseases and PD using stem cell-based modeling systems.
In 2016 she has been awarded a Helmholtz Young Investigator award. Currently, she is an independent Helmholtz Investigator Group Leader at the DZNE Tübingen and Assistant Professor of Neurology at the University of Tübingen. Her research aims at tackling the cell type-specific effect of genetic variants involved in both sporadic and genetic PD, with a focus on the role of innate immunity as an early trigger of PD.
