The Wandall group

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.

Aktuel forskning

Main areas of interest:

• 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

 

Highlights

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.
