Abstract

Studies in mouse models provided evidence that cell death triggers inflammation, however the underlying mechanisms remain elusive. Using relevant genetic mouse models, this project will study the mechanisms by which different types of cell death trigger inflammation in vivo, focusing primarily on apoptosis and necroptosis. Major focus areas will be the in vivo role of specific DAMPs and their receptors as well as the mechanisms determining DAMP release via plasma membrane permeabilisation and their functional consequences in triggering cell death-induced inflammation.
