Siderophore-Based Molecular Imaging of Fungal and Bacterial Infections—Current Status and Future Perspectives

Journal of Fungi, 2020
Invasive fungal infections such as aspergillosis are life-threatening diseases mainly affecting immuno-compromised patients. The diagnosis of fungal infections is difficult, lacking specificity and sensitivity.

Catecholate siderophores protect bacteria from pyochelin toxicity. [PDF]

PLoS ONE, 2012
Bacteria produce small molecule iron chelators, known as siderophores, to facilitate the acquisition of iron from the environment. The synthesis of more than one siderophore and the production of multiple siderophore uptake systems by a single bacterial ...

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Distribution and Cycling of Siderophores in the Eastern North and Tropical Pacific Oceans

Geophysical Research Letters
Most iron (Fe) dissolved in seawater is complexed to organic ligands of unknown composition. Here we investigate the distribution of siderophores, small organic compounds synthesized by microbes to bind environmental Fe and facilitate its transport into ...

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Simultaneous modification of Thermotoga maritima encapsulin subunits to produce multivalent nanoparticle vaccines for non‐typhoidal Salmonella enterica

The FEBS Journal, EarlyView.
This study investigates the modularity of encapsulin—a protein nanoparticle—by simultaneously inserting up to four distinct Salmonella epitopes within the encapsulin subunit. The encapsulin variants were transiently expressed in plants where they assembled into nanoparticles; however, their accumulation and stability varied depending on the ...

Efficacy Assessment of Montanide GEL 02 PR and Liposome‐Based Encapsulation as Adjuvants for an FrpA Subunit Vaccine Against Photobacteriosis in Solea senegalensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Photobacteriosis is a major threat to marine aquaculture, and the siderophore transporter FrpA represents a promising target for effective subunit vaccine development. In this study, we evaluated Montanide GEL 02 PR and phosphatidylcholine‐based liposomes as aqueous and safer alternatives to Freund's adjuvant for an FrpA‐based subunit vaccine ...
