Sphingomyelin as a danger signal in cell-autonomous immunity
Individual cells employ mechanisms of cell-autonomous immunity to defend their cytosol against bacterial invasion. One such mechanism involves indirect detection of the pathogen through recognition of pathogen-induced disturbances causing the appearance of specific host molecules in an abnormal …

Functional analysis of Shigella encoded IpaH E3 ubiquitin ligases in cell-autonomous immunity
… secretion system (T3SS) to manipulate the host cell and counteract anti-bacterial defense pathways. My work demonstrated that IFN-induced guanylate-binding proteins (GBPs) are novel targets for IpaH9.8. GBPs inhibit actin-dependent motility and cell-to-cell spread of bacteria unless they are …

Novel detection and evasion mechanisms pertinent to immunity against Salmonella Typhimurium
Cells defend their cytosol against pathogen invasion using cell-autonomous immunity. When pathogens enter the cytosol they can damage host endomembranes, causing the mislocalisation of host molecules not normally found in the cytosol that are sensed as Danger Associated Molecular Patterns (DAMPs). …

Mechanisms of TRIM21-directed intracellular degradation
… TRIM21 acts as a danger sensor and intracellular effector of humoral immunity. In addition to antibody binding, TRIM21 is a ubiquitin E3 ligase, an enzyme which catalyzes the formation of polymers of the protein ubiquitin around target substrates. When viruses coated in non-neutralizing …

The ubiquitin coat of cytosol-invading bacteria
Cytosol-invading Salmonella enterica serovar Typhimurium are labelled with a ubiquitin coat, which serves the dual purpose of targeting bacteria to autophagy-mediated degradation and locally inducing pro-inflammatory signalling. Importantly, the chain types and ubiquitylated substrates that …
