overview Complex glycans participate in a wide variety of biological phenomena in both health and disease, such as cell differentiation, proliferation, migration, and morphogenesis. We investigate how glycans impinge on cells during development, inflammation, and cancer growth, and how to exploit this for early detection and treatment of disease. We explore and map glycogenes with new enzymatic technologies to turn genes on and off and identify new causes of disease. In addition, we seek to develop new methods to detect mutations in glycogenes and to investigate what changes these infer on the glycome and cellular processes using novel mass spec technologies. Insight into the glycome may lead to new diagnostic tools and better-targeted drugs and vaccines.

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.
Probing function of O-glycosylation by an organotypic skin model This project is dedicated to the discovery and molecular dissection of functions of protein glycosylation with a particular emphasis on O-linked protein glycosylation.
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.
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.
