Sonnen: Signalling dynamics

Back to research groups

The Sonnen group investigates how signalling pathway dynamics encode information to control development and homeostasis of multicellular systems.

Figure 1: Transmitting biological information with signalling dynamics. Information can be encoded in the dynamics of a signalling pathway, for instance in oscillations. The signal can be decoded by reading out the signal in a static (e.g. absolute level at the timepoint highlighted with dashed line) or a dynamic manner.

Signalling pathways coordinate multicellular systems and control cell fate decisions. This way they are absolutely essential to guide embryonic processes such as development, adult tissue homeostasis, regeneration or the immune response. If mutations in signalling pathway components occur, this can for instance result in developmental malformations and disease development such as cancer. Therefore, a long-standing questions in the field of multicellular biology is how signalling pathways function. It has been shown previously that biological information can be encoded in the dynamics (i.e. the temporal change) of a signal. However, most of our knowledge to-date comes from studies using single cells (reviewed in Sonnen and Aulehla 2014). With new technological advancements, we are now at the stage to study how signalling dynamics control development and tissue homeostasis at multicellular level (Sonnen et al. Cell 2018, Sonnen and Merten, Dev Cell 2019). Our work aims at understanding the function and the mechanism of dynamic signal encoding in multicellular systems during embryonic development and adult tissue homeostasis.

Group leader

Katharina Sonnen

Katharina Sonnen is group leader at the Hubrecht Institute. Her group studies how biological information is robustly transmitted via signalling pathway dynamics in multicellular systems. They focus on the role of signalling pathway dynamics (1) during development using mouse somitogenesis as model system and (2) during tissue homeostasis using intestinal organoids as model system. The Sonnen group uses techniques to perturb and quantitatively analyse the dynamics of signalling pathways. They have established a microfluidic system to dynamically modulate intercellular signalling in multicellular systems. In addition, they complement those tools with biochemical and cell biological techniques to unravel the mechanism of dynamic signal encoding at the molecular level.
