Metals in infectious diseases and nutritional immunity
This editorial introduces the ‘Metals in infectious diseases and nutritional immunity’ themed issue for Metallomics, guest edited by Eric Skaar and Manuela Raffatellu.
An evolutionary perspective on zinc uptake by human fungal pathogens
A link between environmental pH and fungal zinc uptake strategies? Soil acidity and endemic mycoses in the USA.
The role of transition metal transporters for iron, zinc, manganese, and copper in the pathogenesis of Yersinia pestis
Yersinia pestis, the causative agent of bubonic, septicemic and pneumonic plague, encodes a multitude of Fe transport systems.
Bacterial iron–sulfur cluster sensors in mammalian pathogens
We review how iron–sulfur cluster-containing regulators contribute to bacterial pathogenesis through control of gene expression in response to environmental cues.
Back to the metal age: battle for metals at the host–pathogen interface during urinary tract infection
Uropathogenic Escherichia coli (UPEC) may produce upto four siderophores during urinary tract infection (UTI). Host cells produce lipocalin, calprotectin and ceruloplasmin during UTI. Arrows indicate the direction of metal transport in UPEC during UTI.
Copper tolerance and virulence in bacteria
Copper (Cu) is an essential trace element for all aerobic organisms.
Copper homeostasis in Mycobacterium tuberculosis
Copper resistance mechanisms in Mtb during infection and sources of host-provided copper are discussed.
Diverging roles of bacterial siderophores during infection
Specialization of siderophore function during infection: Salmochelin (Sal) evades Lipocalin 2 (Lcn2) to scavenge iron, Enterobactin (Ent) promotes lung invasion, and Yersiniabactin (Ybt) binds copper for detoxification and zinc for nutrition.
Contrasting regulation of macrophage iron homeostasis in response to infection with Listeria monocytogenes depending on localization of bacteria
We describe for the first time the changes of iron homeostasis in response to infection of macrophages with Listeria monocytogenes.
Metal selectivity by the virulence-associated yersiniabactin metallophore system
Metal–yersiniabactin complexes are transported intact through the outer membrane receptor, FyuA, in a TonB-dependent manner in uropathogenic Escherichia coli.
Trace element landscape of resting and activated human neutrophils on the sub-micrometer level
Neutrophils and extracellular traps examined by synchrotron radiation X-ray fluorescence and inductively coupled plasma mass spectrometry.
The capability of Pseudomonas aeruginosa to recruit zinc under conditions of limited metal availability is affected by inactivation of the ZnuABC transporter
Zn acquisition in Pseudomonas aeruginosa.
