Keywords
• Signal transduction in inflammation and immunity • Cytokine signaling (TNF, IL-1, IL-33) • Toll-like receptor signaling • NF-kB and IRF signaling • Protein-protein interactions • (De)Ubiquitination • Mouse models of inflammation • Conditional gene targeting in the mouse • Pseudomonas lung infection
Science
The goal of our research is to understand the molecular mechanisms that control inflammation and immunity. We are focusing on specific intracellular signaling cascades, such as the nuclear factor-kB (NF-kB) pathway, which is activated in response to injury, infection, inflammation and other stressful conditions requiring rapid reprogramming of gene expression. Inappropriate NF-kB dependent gene expression is implicated in the pathogenesis of inflammatory diseases and cancer. We are using several molecular and biochemical approaches to elucidate the mechanisms that control NF-kB activation downstream of cytokine receptors (TNF, IL-1, IL-33) and immune receptors (TLRs, TCR). Using conditional gene targeting in the mouse we also study the role of key signaling molecules in mouse models of inflammatory diseases (multiple sclerosis, rheumatoid arthritis, asthma, Crohn’s disease), infectious diseases (Pseudomonas or Influenza lung infection), as well as cancer.
Specific research topics include:
1. Regulation of NF-kB signaling by protein ubiquitination and phosphorylation; 2. Function and regulation of the deubiquitinating protein A20; 3. Function and regulation of the paracaspase MALT1; 4. Cell death signaling in the central nervous system; 5. Modulation of innate immunity by the T3SS of Pseudomonas aeruginosa;
