We use gene editing, organotypic tissue models, and sophisticated mass spectrometry to decipher glycan functions. The genetically engineered cells and organotypic tissue model have provided evidence of the importance of glycans in tissue differentiation, cancer, and host-pathogen interactions.
Modeling Glycobiology
Glycans decorate most proteins and cover all our cell membranes, yet our understanding of how glycans influence the lives of cells and organisms is limited.
We use gene editing, organotypic tissue models, and sophisticated mass spectrometry to decipher glycan functions. The genetically engineered cells and organotypic tissue model have provided evidence of the importance of glycans in tissue differentiation, cancer, and host-pathogen interactions.
We now use organotypic tissue models for broad discovery and dissection of the specific structure-function relationships by which glycans drive normal epithelial formation, transformation and interaction with viruses and the microbiome.
We aim to exploit this knowledge for new and targeted treatments for inflammation, cancer, tissue regeneration, and the development of novel viral vaccine strategies.

GlycoSkin. Our understanding of how glycans influence the life of cells and organisms is limited, and only few functions have been molecularly dissected. We will use step-by-step genetic deconstruction of glycosylation capacities in organotypic tissue models for broad discovery and dissection of specific structure-function relationships driving normal epithelial formation, cancer transformation and interaction between the host and the microbiome.
Production of APC Targeted Allergy Vaccines (APCGlyVac) We hypothesize that recombinant allergy vaccines with defined carbohydrates will target APCs and enhance efficiency, induce tolerance at lower dosages, and possibly reduce side-effects. This proposal aims to explore the potential for enhancing efficiency of recombinant allergens vaccines against major allergens by targeting these to APCs through specific glycosylation patterns.
Copenhagen as the next generation leader in precise genome engineering: The use of a novel genome editing technology has the power to redesign most living organisms with exquisite precision, speed and cost-effectiveness. We have created the Copenhagen Consortium for Designer Organisms as a leading knowledge center on precise genetic engineering using nuclease-based technologies.
Novel proteome-wide discovery strategy for O-glycosylation sites on viral envelope proteins using herpes simplex virus type 1 (HSV-1) as a model. We identified 74 O-linked glycosylation sites on 8 out of the 12 HSV-1 envelope proteins. With the use of precise gene editing, we further demonstrate that elongated O-glycans are essential for HSV-1 in human HaCaT keratinocytes.

Uncovering the function of cancer associated glycan changes using simplified cells and simplified tissues. We demonstrate, with the use of well-defined cell systems generated by precise gene editing, that the aberrant O-glycophenotype by itself induces oncogenic features with enhanced growth and invasion.
