Our lab is generally interested in the molecular mechanisms that determine cell fates
Recently, we have identified a pool of transcription factors that are sufficient to convert skin fibroblasts directly into functional neuronal cells that we termed induced neuronal (iN) cells. This was a surprising finding and indicated that direct lineage reprogramming may be applicable to many somatic cell types and many different directions. Indeed, following our work others have identified transcription factors that could induce cardiomyocytes, blood progenitors, and hepatocytes from fibroblasts.
We are now focussing on two major aspects of iN and iPS cell reprogramming:
(i) we are fascinated by the puzzle how a hand full of transcription factors can so efficiently reprogram the entire epigenome of a cell so that it changes identity. To that end we are applying genome-wide expression analysis, chromatin immunoprecipitation, protein biochemistry, proteomics and functional screens.
(ii) it is equally exciting to now use reprogramming methods as tools to study or treat certain diseases. iPS cells have the great advantage that they can easily be genetically manipulated rendering them ideal for treating monogenetic disorders when combined with cell transplantation-based therapies. In particular we are working on Dystrophic Epidermolysis Bullosa in collaboration with Stanford's Dermatology Department. An exciting application of iN cell technology will be to try modeling neurological diseases in vitro. We perform both mouse and human experiments hoping to identify quantifiable phenotypes correlated with genotype and in a second step evaluate whether this assay could be used to discover novel drugs improve the disease progression.
Our lab is interested in the molecular mechanisms that define neural lineage identity focusing on transcription factors and chromatin biology. We use cellular reprogramming to understand how neurons are induced, how they mature and maintain their identity. Reprogramming also allows us to generate a novel tool box to study human neuronal and glial cell biology which become powerful human disease models in combination with genetic engineering. We further seek to develop reprogramming & genetic engineering approaches towards stem cell-based therapies. Finally, we study microglia-neuron interactions with the ultimate goal to understand the brain's immune system in health and disease and to exploit microglia for therapeutic and regenerative purposes.
Neurosychiatric diseases like autism and schizophrenia are highly complex brain disorders difficult to model in mice in part due to complex genetic etiology and sometimes affecting human-specific genes. We develop novel human cell models to investigate disease-relevant cell biological phenomena.
We have and continue to develop protocols to generate specific types of neurons such as pure glutamatergic and pure GABAergic neurons from human pluripotent stem cells using transcription factors. In combination with genetic engineering or deriving iPS cells from patients, we then interrogate the cell biology of human neurons that carry disease-causing mutations. A particular focus is on synaptic function as shown in the figure on the right on Fragile X Syndrome neurons in collaboration with Lu Chen and Tom Südhof's laboratories.
The ability to generate functional induced neuronal cells from distantly related somatic cell types is fascinating but also offers the opportunity to obtain neurons from a larger cohort of human subjects. In particular blood is readily available and we showed can be efficiently converted into functional neurons from young and aged donors.
The combination of reprogramming and gene editing is truly powerful as it provides exciting new possibilities to generate cells that can be transplanted and have disease modifying activity. We currently apply this approach to restore mono-genetic diseases, but our vision goes beyond simple regenerative medicine. We will be able to genetically engineer designer cells that functionally integrate into diseased tissue equipped with sensing and intelligent disease-response mechanisms.
Dystrophic Epidermolysis Bullosa is a severe, blistering monogenetic skin disease caused by mutations in the gene coding for type VII collagen. We have developed a 1-step gene editing/iPS cell reprogramming method to rapidly generate patient iPS cells corrected for their disease-causing mutations in the Collagen7a1 gene. In collaboration with dermatologist Tony Oro we are developing a cell manufacturing process compatible with Good Manufacturing Procedures (GMP) to obtain FDA-approval for a first in man Phase I clinical trial with with a genetically engineered iPS cell product.
Both oligodendrocyte precursor cells as well as microglia can efficiently repopulate the brain. We are interested in exploiting the properties of these cells to develop novel cell therapies for the brain either to use the transplanted cells to restore function such as myelination, to alter the function of transplanted cells for therepeutic benefit, to use the cells as vehicles for therapeutic molecules, or ultimately to develop designer cells that are engineered with genetic synthetic biology circuits to sense and interfere with disease processes of the brain.
We are interested in the molecular mechanisms that define neuronal and glial cell identity. We found sets of transcription factors that can convert fibroblasts or lymphocytes into neurons and oligodendrocytes. These factors are also operational during normal development and are largely responsible to induce terminal lineages from progenitor cells.
We found that Ascl1, one of our reprogramming factors, has a unique ability to access its physiological targets even in fibroblasts where these sites are in a closed chromatin configuration. We are fascinated by this "on target" pioneering property and are investigating how Ascl1 can access its target sites in an unfavorable chromatin environment and how it then remodels the chromatin at these sites to activate the neuronal transcriptional program.
Once neurons are made, there ought to be also mechanisms that maintain neuronal identity. We stumbled upon a novel repressive mechanism: The neuronal-specific transcription factor Myt1l continuosly represses many non-neuronal programs in neurons leaving the neuronal program open to activate by other factors and thereby ensuring stable neuronal gene expression. Myt1l was also recently found to be mutated in autism and schizophrenia.
Microglia, the brain's resident immune cells, are fascinating cells. They are derived from yolk sac progenitor cells early during development, are long-lived, and are not exchanged from bone marrow progenitor cells under physiological conditions. Microglia have been implicated in synaptic pruning, adult neurogenesis, and various brain diseases including Alzheimer's disease and Schizophrenia.
We have developed a method to efficiently replace endogenous microglia from circulating cells without genetic manipulation. This does not happen physiologically but under certain conditions peripheral blood cells cross the blood-brain-barrier, migrate into the brain parenchyma and replace endogenous cells. We are investigating the cellular and molecular signals that enable circulating cells to invade the brain in order to further improve microglia replacement strategies.
Our ability to replace microglia provides us with a powerful tool to functionally perturb microglia function in normal and disease states. E.g. the microglial gene TREM2 is a strong Alzheimer's disease risk gene, but major questions about the neuro-immune interplay in the context of neurodegeneration and aging remain unsolved. Microglia replacement also provides an exciting prospect to develop novel cell therapies for a variety of brain diseases including enzyme deficiency syndromes, neurodegeneration, and brain tumors.

RTN4-binding proteins were widely studied as "NoGo" receptors, but their physiological interactors and roles remain elusive. Similarly, BAI adhesion-GPCRs were associated with numerous activities, but their ligands and functions remain unclear. Using unbiased approaches, we observed an unexpected convergence: RTN4 receptors are high-affinity ligands for BAI adhesion-GPCRs. A single thrombospondin type 1-repeat (TSR) domain of BAIs binds to the leucine-rich repeat domain of all three RTN4-receptor isoforms with nanomolar affinity. In the 1.65 Å crystal structure of the BAI1/RTN4-receptor complex, C-mannosylation of tryptophan and O-fucosylation of threonine in the BAI TSR-domains creates a RTN4-receptor/BAI interface shaped by unusual glycoconjugates that enables high-affinity interactions. In human neurons, RTN4 receptors regulate dendritic arborization, axonal elongation, and synapse formation by differential binding to glial versus neuronal BAIs, thereby controlling neural network activity. Thus, BAI binding to RTN4/NoGo receptors represents a receptor-ligand axis that, enabled by rare post-translational modifications, controls development of synaptic circuits.

I joined the Wernig lab as an LSRP in the summer of 2022 after graduating from UCLA. I’m interested in the regenerative capabilities of the human body and the molecular mechanisms underlying these regenerative systems, as well as the ways in which we can utilize these mechanisms to treat disease via tools such as cell and gene therapy. My research interests further include immunological topics such as cancer biology and the coevolution of pathogenic species and the immune response. In the Wernig lab, I am investigating methods of replacing dysfunctional microglia in the CNS in the context of neurodegenerative diseases, as well as the translational potential of gene editing and the role that genetically manipulated cells can play in treating such diseases. Outside the lab, I enjoy spending time at the beach, watching sports, and going on road trips with my friends.

Christian's project focused on the function of synaptic proteins in the context of human neurons. Brain research has made tremendous advances in the last decades using animal models. However, most neuropathological conditions, such as autism or schizophrenia, are unique to human physiology. Thus, I study the effect of genetic alterations of synaptic proteins in induced human neurons using immunohistochemistry, analysis of gene and protein expression, as well as electrophysiology. Christian moved on to a senior lecturer position at the newly formed university of Linz, Austria. Good luck there!
Graduating from UC Berkeley majoring in Biology with an honors in Neuroscience, and having worked as an MD at the Royal Melbourne Hospital, I have developed a particular interest in translational neuroscience. In the lab, I am investigating the efficacy of cell therapies for neurological disorders. I am currently working on microglia based therapies for major neurological diseases, including multiple sclerosis.
I am a molecular biologist with a focus on neuro- and cancer biology. I am interested in using human iPSCs to develop new in vitro disease models, particularly for neuropsychiatric disorders and neurooncology. This led me to the Wernig lab where I started my postdoc to explore the advantages of direct neuronal reprogramming and the intricacies of step-wise differentiation of neural cell types. I am genetically engineering iPSC lines to generate complex genomic alterations and inducible mutations. Following differentiation into the corresponding disease-relevant tissue, I am puzzling together cellular phenotypes, transcriptional regulation, protein interactions, and epigenetic changes for a better understanding of the disease biology. In my spare time, I enjoy a new definition of chaos by my 2-year-old daughter.

My PhD mentor is Dr. Xiaodong Wang, who is a chinese-born American biochemist best known for his work with cytochrome C on apoptosis. He is a member of United States National Academy of Sciences and Howard Hughes Medical Institute.
During my PhD stage, my major work is to try and find function of a protein named RIP3 in necrosis (other program cell death) pathway. I use human fetal neural stem cells to study mutation caused epigenetic rigidity in reprogramming process. A lot of patient diseases are caused by gene mutation, but we do not know which kind of cells and which site of mutate will cause disease. We try to work on neural stem cells to induce some point mutation to imitate brain cancer disease from reported mutation site in human patient. Then we will know which mutation site is the key and try to fix it by the biology method.
The immense potential of genetic engineering technology as a tool to understand disease mechanisms and as a therapy motivates me to pursue research. I am studying CRISPR/Cas9 mediated gene correction of mutations in patients suffering from Epidermolysis bullosa. I am also studying iPSC-derived induced neurons to model neurological disorders.

With billions of neurons interconnected with many billions of synapses, our brain is the most complex object in the known universe. I like to think that I’m doing my part in understanding it. I use human neurons to study a synaptic protein called Neuroligin 4 that is not found in mice, therefore very complicated to study but at the same time extremely fascinating. When mutated Neuroligin 4 causes Autism and impairs the synaptic transmission of neurons. After leaving his prominent imprint on the lab he moved on to join the faculty at Mount Sanai School of Medicine in New York. Good luck Samuele, we will miss you!
