Research groups
Our international research groups investigate viral traits and immune defence mechanisms, metabolic regulation and the equilibrium between tissues, as well as the development and functioning of the nervous system. These research areas are important to human health in connection with, for example, infectious diseases, metabolic disorders and cancer as well as brain diseases and mental health.

To tackle this question, we use a multidisciplinary approach combining state-of-the-art techniques in cell biology, biochemistry and structural biology.

Extracellular Vesicles
Group leader: Pia Siljander

The EV group studies extracellular vesicles (EVs), submicron membrane vesicles released by most cells (mammalians to prokaryotes), that are present in all body fluids, but also e.g., in oceans.

F

Functional Lipidomics Group

G

Glycoscience Group
Group leader: Jukka Finne

The Glycoscience group headed by professor Jukka Finne is engaged with the biology of carbohydrates, the most abundant biological molecules of nature, involved in the biology of all living organisms. Glycans have received little attention due to lack of efficient tools to probe their complex structures and properties.

I
