Project Title

Deciphering the Modulation of Insulin Receptor Signaling during Differentiation of Human iPSCs to β-like Cells

Project description

My project focuses on insulin receptor signaling in human pancreatic beta cell cells during development and adulthood as well as under diabetic conditions. In particular, I am interested in the characterization of two novel modulators of the insulin receptor signaling cascade, which our lab recently discovered. Therefore, I am working with human induced pluripotent stem cells, which can be genetically modified via CRISPR/Cas9 and differentiated towards beta like cells. This in vitro system provides a model of maturing beta cells as well as beta cell development and allows for the translation of findings from mouse models to human cells.
