Bacterial iron homeostasis | FEMS Microbiology Reviews

Bacterial iron storage proteins (ferritin, bacterioferritin) provide intracellular iron reserves for use when external supplies are restricted, and iron ...

Key players in the regulation of iron homeostasis at the host ...

Hepcidin, initially identified as a cysteine-rich antimicrobial peptide, has been found to play a crucial role in iron regulation during inflammation and ...

Bacterial iron homeostasis - ScienceDirect.com

Bacteria have evolved various mechanisms to counter the problems imposed by their iron dependence, allowing them to achieve effective iron homeostasis under a ...

Bacterial iron detoxification at the molecular level

Iron is an essential micronutrient, and, in the case of bacteria, its availability is commonly a growth-limiting factor.

Breaking Iron Homeostasis: Iron Capturing Nanocomposites for ...

Upon bacterial infection, the host restricts Fe ions, which are crucial for bacterial growth and maintenance. Having coevolved with the host, ...

The Ins and Outs of Bacterial Iron Metabolism - PMC - PubMed Central

Iron is a critical nutrient for the growth and survival of most bacterial species. Accordingly, much attention has been paid to the ...

Dps Functions as a Key Player in Bacterial Iron Homeostasis

A crucial role in iron homeostasis is played by Dps (DNA binding proteins in starved cells) in prokaryotes. We also look at the emerging ...

Bacterial Iron Homeostasis Regulation by sRNAs - ASM Journals

In this review, we will summarize knowledge on how sRNAs control iron homeostasis mainly through studies on RyhB in Escherichia coli.

Control of bacterial iron homeostasis by manganese - PNAS

In the present study, we show that manganese controls iron homeostasis in B. japonicum. The data support the conclusion that manganese interferes with the role ...

Natural flavonoids disrupt bacterial iron homeostasis to potentiate ...

Bacterial iron homeostasis

For pathogens, host^iron complexes (transferrin, lactoferrin, haem, haemoglobin) are directly used as iron sources. Bacterial iron storage proteins (ferritin, ...

Host and Bacterial Iron Homeostasis, an Underexplored Area in ...

Furthermore, Mtb infection was shown to impair iron absorption and alter host iron homeostasis. The observation that iron levels and deposition ...

Iron homeostasis in host and gut bacteria – a complex interrelationship

The aim of this review is to provide further insights into the complex relationship between iron and gut microbiota.

O2 availability impacts iron homeostasis in Escherichia coli - PNAS

Iron homeostasis requires coordination between iron uptake, storage, and cofactor synthesis to supply iron for the iron-containing proteome (1–3) ...

Microbial Metabolite Signaling Is Required for Systemic Iron ...

In this study, we show that gut microbiota regulate systemic iron homeostasis in the host in two ways: by repressing intestinal iron absorptive ...
