Max Planck Institute for Immunobiology and Epigenetics, Freiburg, Germany
Quantitative single cell biology

 This project will follow the temporal succession of haematopoietic differentiation transitions in Reaggregate Thymus Organ Culture (RTOC) with single cell resolution.

We will

  • characterize the population composition of precursor cells in the thymus at subsequent time points, and investigate the differentiation dynamics of all haematopoietic cell lineages populating the thymus.
  • perform a detailed analysis of the kinetics of progenitor stage transitions, in order to understand the dynamics of cell transitions through subsequent niches and the underlying gene regulatory changes.
  • test the response of the differentiation trajectories to a perturbation of the Notch signalling pathway, which is critical for T cell differentiation.

A02 Eirini Trompouki
Max Planck Institute for Immunobiology and Epigenetics, Freiburg, Germany

 This project will provide insights into the transcriptional dynamics of haematopoietic stem cells under perturbed inflammatory signalling and the mechanism of activation of Retinoic acid inducible gene 1 Like Receptors (RLRs) in the absence of viral infection. It dissects how RLRs modulate haematopoiesis over time (HSC formation, expansion and maintenance) in different compartments (AGM, FL and BM) We will

  • explore single cell transcriptomes of Rig-I-/- and Mda5-/- HSCs in AGM, FL and BM.
  • identify transcription factors responsible for transcriptional changes in knockout mice.
  • discover new RLR ligands under steady state and regenerative conditions.

Neurodevelopment, epigenetics

 This project resolves the mechanism of histone methyltransferase DOT1L-associated defects in CNS development and aims at understanding DOT1L-mediated transcriptional control and chromatin properties. Analysing mother and daughter cells that arise at different developmental time points and populate different locations depending on the division mode shall reveal the spatio-temporal dynamics of DOT1L function with high resolution. We will

  • explore the DOT1L-dependent transcriptome in individual cells in one cell lineage during cortical differentiation.
  • explore the DOT1L-dependent transcriptome and chromatin properties in progenitors and differentiated progeny after DOT1L-deletion in larger, yet defined cell populations of progenitors or differentiated neurons.

Embryonic development

 This project characterises dynamic transcriptome changes between neural stem cells, proliferating precursors, differentiating and mature DA neurons in vivo, and aims to identify specific epigenetic mechanisms involved in these transitions. To resolve potential specific Mll1 activities, we will investigate effects of its inhibition or knock-out on the dynamic transcriptome during neurogenesis. We will

  • Characterise dynamic transcriptome profiles during neurogenesis from stem cell to mature DA neuron. These data will define steps in neurogenesis and identify potential new regulators of dopaminergic neurogenesis.
  • Identify epigenetic mechanisms of DA neurogenesis by identifying specific genes regulated by TrxG/Mll1 dependent mechanisms.

Plant development

 In this project we want to resolve the role of chromatin dynamics for the specification of cell fate in the CSC niche. The spatial dynamics will be investigated along the WOX5-protein gradient in the CSC niche and data along the temporal axis will be obtained from CSC niches at different ages. We will

  • Isolate nuclei from specific cell types of the CSC niche by fluorescence activated nuclei sorting (FANS).
  • Generate cell specific RNA-seq and ChIP-seq profiles.
  • identify candidate genes differentially regulated in the CSC niche by WOX5-mediated chromatin changes and aging.
  • verify candidate genes in vivo.

Cell death/survival

 This project investigates the effects of PI3K/AKT/GSK-3 and CDK-9 dependent phosphorylation of TIP60 on transcriptional control and chromatin properties. We will:

  • investigate the spatial distribution of wildtype TIP60 as compared to the phosphorylation mutants TIP60S86A and TIP60S90A on a genome wide level.
  • Analyse histone 4 acetylation, S2P and S5P RNA PolII distribution patterns in cells expressing wild-type TIP60, TIP60S86A, and TIP60S90A, and correlate RNA expression in these cells.
  • Analyse the spatial distribution of TIP60 and gene expression after pharmacological inhibition of PI3K, GSK-3, and CDK-9 kinase activity and correlate these data to the genome-wide distribution data obtained from TIP60 wildtype and phosphorylation mutants.

 This project aims at understanding the function of SNAIL1 as a transcriptional activator during epithelial-mesenchymal transitions  (EMT). It will study TGFβ-induced gene expression changes, spatio-temporal dynamics of SNAIL1 chromosomal distribution and SNAIL1-dependent changes in chromatin structural features. We will:

  • identify the genes subject to direct transcriptional activation by SNAIL1 during EMT.
  • structurally and functionally characterise cis-regulatory DNA elements involved in SNAIL1-mediated transcriptional activation.
  • identify signal transduction pathways and transcription factors that cooperate with SNAIL1 in gene activation.
