Copper Transport and Trafficking at the Host–Bacterial Pathogen Interface
CONSPECTUS: The human innate immune system has evolved the means to reduce the bioavailability of first-row late d-block transition metal ions to invading microbial pathogens in a process termed "nutritional immunity". Transition metals from Mn(II) to Zn(II) function as metalloenzyme cofactors in all living cells, and the successful pathogen is capable of mounting an adaptive response to mitiga...
متن کاملMicrobial Copper-binding Siderophores at the Host-Pathogen Interface.
Numerous pathogenic microorganisms secrete small molecule chelators called siderophores defined by their ability to bind extracellular ferric iron, making it bioavailable to microbes. Recently, a siderophore produced by uropathogenic Escherichia coli, yersiniabactin, was found to also bind copper ions during human infections. The ability of yersiniabactin to protect E. coli from copper toxicity...
متن کاملSumoylation at the Host-Pathogen Interface
Many viral proteins have been shown to be sumoylated with corresponding regulatory effects on their protein function, indicating that this host cell modification process is widely exploited by viral pathogens to control viral activity. In addition to using sumoylation to regulate their own proteins, several viral pathogens have been shown to modulate overall host sumoylation levels. Given the l...
متن کاملCommunication at the host-pathogen interface
The oral cavity represents a finely balanced ecosystem in which a plethora of bacterial species lives in complex communities known as biofilms. To cohabitate efficiently, bacteria within these biofilms have evolved intricate systems of communication, such as quorum sensing, cooperation or competition, involving signaling, sharing of resources and/or metabolic activities. Dysbiosis can develop a...
متن کاملStructural microbiology at the pathogen-host interface.
Bacterial pathogens achieve the internalization of a multitude of virulence factors into eukaryotic cells. Some secrete extracellular toxins which bring about their own entry, usually by hijacking cell surface receptors and endocytic pathways. Others possess specialized secretion and translocation systems to directly inject bacterial proteins into the host cytosol. Recent advances in the struct...
