Mission of the group of Neural Stem Cells and Neuroimaging is the elucidation of the proliferation, differentiation and reprogramming properties of adult-derived Neural Stem Cells (NSCs) and parenchymal macroglia (astrocytes and microglia) in vitro and in vivo in animal models of brain lesion, neuroinflammation and neurodegenerative diseases. Our ultimate goal is to reveal the mode of action of new molecules in promoting neurogenesis and/or neurogenic reprogramming and restricting brain inflammation and use them to reduce neurodegeneration/ neuroinflammation.
The research of the group focuses on the investigation of the mechanism of action of novel genes, miRNAs and small molecules in 1) inducing direct neurogenic reprogramming of brain astrocytes in vitro and in vivo and 2) modifying microglia properties during Alzheimer’s Disease (AD) progression. To this end we are using a) primary mouse and human astrocytic cultures, b) recombinant viral vectors expressing proteins/ miRNAs of interest and c) inducible transgenic mice with cell type-specific and time-regulated protein expression or down-regulation to:
- Explore the regenerative potential and reveal the mechanism of action of neurogenic genes and neurogenesis-modulating miRNAs in driving brain astrocytes direct reprogramming to induced-neurons: in vitro applying molecular phenotype, functional and NGS analysis and in vivo, by astrocyte-specific forced expression of neurogenic molecules into the injured mouse brain.
- Follow, by whole animal 2-photon (2P) imaging, NVU dynamics in real time following brain injury and inflammation. To this end our group has established in the Institute’s Light Microscopy Unit (LMU) 2P intravital imaging of the CNS.
- Study the role of the late-onset AD risk factor BIN1 on microglia activation and its contribution in AD progression, by real time mouse brain intravital 2P-imaging to monitor dynamic microglia properties and interactions and by single cell NGS analysis to reveal activated microglia states and non-cell autonomous functions in the absence of microglial BIN1.
- Study the effect of chemical brain lesion on adult neurogenesis occurring in neurogenic and non-neurogenic brain areas by performing in vivo lineage tracing to elucidate the origin and final fate of newborn neurons.
Generation of neurons by in vitro direct reprogramming of mouse and human cortical astrocytes and embryonic fibroblasts
Direct lineage reprogramming has emerged as a promising, fast approach for manipulating cell fate to obtain customized functional neuronal cell types. A step further, utilization of endogenous brain cells that can be directly reprogrammed into neurons, remains a challenge with important clinical applications for the treatment of neurodegeneration.
Recent studies demonstrate that various cell types, including brain astrocytes and skin fibroblasts, can be reprogrammed to neural precursor cells (NPCs) and neurons via challenging certain genes levels. Our aim is to investigate whether in lineage distant somatic cell types residing inside and outside the CNS can be turned into NPCs and neurons upon forced expression of factors that induce neurogenesis during development. To this end we have demonstrated that: a) the neurogenic molecule CEND1 can reprogram mouse astrocytes towards GABA+ neurons and acts synergistically with NEUROG2 to trans-differentiate them towards proliferating NPCs and subtype-specific neurons, b) CEND1 and NEUROG2 possess a broader neurogenic potential, inducing neuronal reprogramming of MEFs , c) CEND1 is a key downstream player in NEUROG2-induced astrocytic reprogramming participating in a positive feedback loop leading to neurogenesis and d) Double over-expression of CEND1 and NEUROG2 results in activation of Wnt/ beta-catenin signaling pathway driving astrocytes to acquire NSC multipotent character. Taken together, our results demonstrate that CEND1 is not only a potent inducer of neuronal differentiation in neural precursor cells as previously shown (Katsimpardi et al., 2008), but has a neurogenic capacity in different cell contexts. Currently we are expanding our studies to exploiting the mechanisms of direct cell reprogramming of human primary astrocytes to functional neurons through neurogenic molecules forced expression.

Mechanisms of direct reprogramming of reactive astrocytes to differentiated neurons in vitro and in vivo following forced expression of neurogenic miRNAs
Our group is interested in studying the molecular mechanisms governing direct lineage reprogramming to induced neurons (iNs), as well as, exploiting the mode of action of neurogenic miRNAs in promoting neuronal trans-differentiation of somatic cell types. miRNAs have emerged as critical post-transcriptional modulators of gene expression by simultaneously targeting multiple genes, thus they appear as attractive candidates to regulate direct cell reprogramming through fine-tuning the expression levels of neurogenic factors. Our efforts are focusing towards the identification of miRNAs that are potent to induce direct cell reprogramming of primary astrocytes to induced-neurons (iNs) in vitro and in vivo and elucidation of their mechanisms of action at the transcriptional and post-transcriptional level. To this end we are using neurogenic miRNA-mimics and recombinant viral vectors expressing selected neurogenic miRNAs along with fluorescent proteins to: a) in vitro explore the coding and non-coding transcriptome profile of reprogrammed astrocytes with next generation sequencing and functional assays and b) assess the capacity of certain neurogenic miRNAs to instruct direct neuronal reprogramming of astrocytes following their in vivo forced expression in animal models of brain trauma.

An open window into the brain through intravital 2-photon imaging: Study of Neurovascular Unit (NVU) interactions and astroglia-microglia dynamics in brain inflammation and disease
The term “Neurovascular Unit” (NVU) is used to describe the integrated system of vascular and neuronal cells and the surrounding glia working in concert to enable proper brain homeostasis and function. The NVU is affected in many CNS conditions and plays a role in their pathology thus study of the cellular interactions in the pathological NVU could contribute to the identification of numerous potential targets for treatment in the context of CNS neurodegeneration/ neuroinflammation. The dynamics of such processes can be adequately captured by in vivo 2-photon imaging, which allows the study of cellular responses to environmental stimuli and cell-cell interactions in the living brain in real time. Accordingly, to explore the dynamic interactions of the NVU following acute and chronic brain injury, we are monitoring by intravital 2-photon imaging the morphological changes of perivascular astrocytes, as well as their dynamic interactions with perivascular microglia and blood vessels under physiological conditions and during LPS-induced systemic inflammation or laser-induced acute brain injury, using transgenic mice expressing fluorescent proteins under astroglia-, microglia- and pericyte-specific promoters. In a parallel project, led by Dr. Vasso Kyrargiri, microglia-specific transgenic mice are used to visualize by intravital 2-photon imaging microglia dynamics in a mouse model of demyelination.

Chemobrain: Effect of chemotherapy on adult neurogenesis occurring in neurogenic and non-neurogenic brain areas
Adult mammalian brain neural stem/progenitor cells have a spatially restricted distribution and neurogenesis takes place only in specific brain areas. However recently, it has been proposed that a low level of neurogenesis also occurs in “non-neurogenic regions”, such as the striatum and to a lesser extent the cortex. Importantly, brain lesions have succeeded to unmask neurogenic activity in such regions in laboratory rodents. To this end we are investigating whether disturbance of the adult mouse SVZ, through stereotaxic intraventricular injections of mitotoxic/chemotherapeutic agents activates cells of neighboring non-neurogenic regions to acquire a neural progenitor potential. Our current data support the hypothesis that administration of mitotoxic/chemotherapeutic agents in the cerebrospinal fluid (CSF) is responsible for SVZ disruption and ectopic presence of newborn neurons in non-neurogenic areas. The fact that several mitotoxic factors are widely used as chemotherapeutic agents and that patients undergoing chemotherapy exhibit progressive cognitive deficits, raises the question whether these treatments lead to disruption of neurogenesis. Therefore, further study of this SVZ-disorganization model will shed light into important questions related to NPCs and parenchymal brain cells’ response to chemotherapeutic treatment.

Microglia dynamics and response to neuroinflammation in the absence of AD risk factor BIN1
A number of recent studies highlight the contribution of microglial cells in AD progression, rendering them a potential cell target to combat the disease. BIN1 is the second most important sporadic AD risk factor with high expression levels in microglia, however the contribution of BIN1 different expression levels in microglial cells in response to neuroinflammation and AD pathogenesis and both in humans and animal models has not been investigated yet. In this project we use transgenic mice harboring fluorescent microglia cells not expressing BIN1, to investigate by single cell transcriptomics and live cell imaging microglial cells distinct activation signatures and states, as well as, their impact on the other glial and neuronal cell types.
