Modeling human early pregnancy with stem cells” The blastocyst is the early mammalian organism before implantation in the uterus. We have promoted the self-organization of stem cells into models of mouse and human blastocysts, which we have named blastoids (Nature 2018, Nature 2021). Blastoids are morphologically and transcriptionally similar to the blastocyst and contain analogs…

“Infections and hematopoietic stem cells: how do they communicate?” Infections are primarily cleared by immune cells in our bodies. However, we observed that the most immature hematopoietic stem cells also contribute to this process. In this lecture, we will report on the mechanisms that activate an hematopoietic stem cell during infection and the cellular adaptations that…

“Tipping the Lipid Scales: Negative Feedback Regulation via ORMDLs Protein Degradation Ensures Sphingolipid Homeostasis” Sphingolipids are essential lipid molecules that contribute to cellular structure and signaling. Their de novo synthesis is initiated in the endoplasmic reticulum (ER) and catalyzed by the multimeric serine palmitoyltransferase (SPT) complex. The ER-resident ORMDL proteins are well-established regulators of sphingolipid…

“RNA cap methylation in poxviruses and coronavirus – differences and similarities” RNA methyltransferases (MTases) are responsible for synthesizing the 5' RNA cap, which plays a crucial role in RNA stability and efficient translation. Over the past two years, both our research team and others have developed numerous inhibitors targeting coronaviral MTases. Through our efforts, we…

“Birds do it their way: avian interferon regulatory factors (almost) resolved” Interferon regulatory factors (IRFs) are transcription factors that play a key role in vertebrate innate antiviral immunity. IRF3 and IRF7 activate the expression of IFN-β, which in response induces the assembly of STAT1, STAT2 and IRF9 into the ISGF3 complex. Subsequently, this complex activates…

“PIP2-RNA-protein interactions in phase separation of Pol II transcription” The RNA Polymerase II transcription is a multifaceted process crucial for gene expression in eukaryotic cells. Over the last decade, liquid-liquid phase separation (LLPS) was shown to be crucial in regulation of RNA pol II transcription. We have shown that nuclear phosphoinositides are pivotal for regulating biological…

“Analysis of a novel chicken Pax6 mutant” Pax6 is known as the "master control gene" for eye formation, playing a crucial role in the development of the lens, retina, and other ocular structures. It drives the formation of the eye field, initiates lens differentiation, and helps establish the retina—all vital for vision. While the role of Pax6 in…

“Transmembrane adaptor protein WBP1L: searching for its binding partners to understand its role in hematopoiesis” Transmembrane adaptor protein WBP1L, also known as Outcome Predictor of Acute Leukemia 1 (OPAL1) was identified nearly 20 years ago as a positive prognostic marker in childhood acute lymphoblastic leukemia. More recently, elevated WBP1L expression has also been linked to…
