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.

Primære forskningsområder

  • Glycan functions in tissue homeostasis, stem cell biology, and regenerative medicine
  • Glycans in host-pathogen interactions (Bacteria, Virus, and parasites)
  • Creation of disease models
  • Impact of glycans on inflammation, cancer, and degenerative diseases

Aktuel forskning

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.

Precise Cancer Targeting of Cancer Associated Glycans Changes in protein and lipid glycosylation are one of the most consistent alterations in human cancers. We use the next generation of genetically engineered 3D tissue models to systematically address the effect of cancer associated glycans in cancer biology and to develop cancer specific treatments. We have identified O-linked glycosylation signatures on proteins and developed a series of cancer specific mAbs to exploit O-glycan signatures for the precise targeting of cancer.

GlycoVirology: Probing the Functions of Glycosylation in Viral Biology  This project aims to 1) characterize glycans on enveloped viruses using mass spectrometry and 2) to examine the glycan functions in virus biology using our comprehensive library of genetically engineered cells. We particularly focus on the importance of site-specific O-glycosylation. We have demonstrated that HSV-1 and other herpesviruses are heavily O-glycosylated and that this type of glycosylation is important for virus propagation and early immune sensing. The project will expand our knowledge on glycosylation in virus biology and help develop antivirals and vaccines. The project is heading by Assistant Professor Dr. Ieva Bagdonaite.

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 continuously implement the novel precise genetic engineering 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.

Education and Training: PhD in Glycobiology (2004); Permission to practice independently as a physician (2001); Medical Doctor UCPH (1999)

Scientific Focus: We investigate how glycans impinge on cells during tissue development, host-pathogen interactions with emphasis on viral infections,  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 and establish how glycans influence protein function. 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.
