Enteropathogenic Escherichia coli (EPEC) is a major cause of paediatric diarrhoea and a model for the family of attaching and effacing (A/E) pathogens. A/E pathogens encode a type III secretion system to transfer effector proteins into host cells. The EPEC Tir effector protein acts as a receptor for the bacterial surface protein intimin and is involved in(More)
Enteropathogenic Escherichia coli (EPEC) are a major cause of paediatric diarrhoea and a model for the family of attaching and effacing (A/E) pathogens. Enteropathogenic Escherichia coli encode a type III secretion system (TTSS) to transfer effector proteins into host cells, a process which is essential for virulence. In addition to generation of A/E(More)
Salmonella virulence depends on an ability to invade host cells, which is in turn dependent on a type III protein secretion system encoded in Salmonella pathogenicity island 1 (SPI1). Several protein targets of the SPI1-encoded secretion system are translocated into host cells, where they subvert cellular processes that contribute to bacterial invasion,(More)
Dynamic subcellular distributions of signaling system components are critical regulators of cellular signal transduction through their control of molecular interactions. Understanding how signaling activity depends on such distributions and the cellular structures driving them is required for comprehensive insight into signal transduction. In the activation(More)
The neuropeptide galanin has diverse roles in the central and peripheral nervous systems, by activating the G protein-coupled receptors Gal1, Gal2 and the less studied Gal3 (GalR1-3 gene products). There is a wealth of data on expression of Gal1-3 at the mRNA level, but not at the protein level due to the lack of specificity of currently available(More)
