Uris Ros – Integrative Cell Death
(Artwork by Orlando QuinteroTesoro)
Membrane damage can be induced by external factors such as mechanical and chemical stress, microbial attack, or the action of immune cells, or from within the cell through the activation of cell death pathways. This damage is sensed by cells, which can integrate the response to different forms of membrane damage into common repair and response principles. The interplay of these processes determines how cells and tissues cope with danger and damage signals, and thus influences the activation of the immune system.
Our group aims to unravel the general principles that explain the link between membrane damage and different forms of regulated cell death and signaling pathways. To this end, we use an integrative approach that combines multiscale screening methods with state-of-the-art molecular and cell biology, biochemistry, and membrane biophysics. The overall goal is to gain insight into the molecular mechanisms underlying the regulation of key components of these networks in cells, which will guide the development of novel strategies to therapeutically target inflammatory diseases.
