About

Professor Sven Pettersson, MD & PhD, is a cell biologist focusing on microbiome mediated mechanisms regulating mammalian host physiology. Ongoing projects seek to decipher microbiome mediated signalling pathways and metabolites that support cell metabolism relevant to neurons and muscle cells.

​Prof Pettersson is a strong proponent of the holobiont concept, which considers human beings as a composite of several different microorganisms that together with the mammalian genome collectively determine body, mind and function. He is highly recognized for discovering a link between the microbial communities in our gut and the development and function of the brain. Ongoing work is directed towards the identification of signaling pathways an microbial metabolites contributing ot gut microbe-brain communication.
