Iron-carbohydrate complexes treating iron anaemia: Understanding the nano-structure and interactions with proteins through orthogonal characterisation

Antonia Neels, Marianne Liebi, Tiberiu Totu

Intravenous (IV) iron-carbohydrate complexes are widely used nanoparticles (NPs) to treat iron deficiency anaemia, often associated with medical conditions such as chronic kidney disease, heart failure and various inflammatory conditions. Even though a ple ...

Dissecting the role of biliary epithelial cells during non-alcoholic fatty liver disease progression

Ece Yildiz

The liver is the largest solid organ and the only one capable of using regenerative mechanisms to recover its mass fully. Although liver regeneration from acute injuries has been effective and extensively studied, chronic liver damage has adverse effects o ...

Iron status influences non-alcoholic fatty liver disease in obesity through the gut microbiome

Xavier Fernandez-Real Girona

Background: The gut microbiome and iron status are known to play a role in the pathophysiology of nonalcoholic fatty liver disease (NAFLD), although their complex interaction remains unclear. Results: Here, we applied an integrative systems medicine approa ...

Catalytic effects of photogenerated Fe(II) on the ligand-controlled dissolution of Iron(hydr)oxides by EDTA and DFOB

Janet Gordon Hering

Low bioavailability of iron due to poor solubility of iron(hydr)oxides limits the growth of microorganisms and plants in soils and aquatic environments. Previous studies described accelerated dissolution of iron(hydr)oxides under continuous illumination, b ...

Iron sequestration by transferrin 1 mediates nutritional immunity in Drosophila melanogaster

Bruno Lemaitre, Jean Philippe Boquete, Alice Marra, Igor Iatsenko

Iron sequestration is a recognized innate immune mechanism against invading pathogens mediated by iron-binding proteins called transferrins. Despite many studies on antimicrobial activity of transferrins in vitro, their specific in vivo functions are poorl ...

The metabolite BH4 controls T cell proliferation in autoimmunity and cancer

Kai Johnsson, Jairo Alexander Lozano Moreno, Yann Mathieu Pierson

Genetic regulators and environmental stimuli modulate T cell activation in autoimmunity and cancer. The enzyme co-factor tetrahydrobiopterin (BH4) is involved in the production of monoamine neurotransmitters, the generation of nitric oxide, and pain(1,2). ...

Applying a Trojan Horse Strategy to Ruthenium Complexes in the Pursuit of Novel Antibacterial Agents

Paul Joseph Dyson, Lucinda Kate Batchelor

Siderophores are iron chelators secreted by bacteria to scavenge iron(III) from their surrounding environment. They possess their own internalization pathway that is sufficiently unselective to be hijacked, making them suitable for Trojan Horse strategy ap ...

Iron phosphate nanoparticles for food fortification: Biological effects in rats and human cell lines

Christian Ludwig

Nanotechnology offers new opportunities for providing health benefits in foods. Food fortification with iron phosphate nanoparticles (FePO4 NPs) is a promising new approach to reducing iron deficiency because FePO4 NPs combine high bioavailability with sup ...

Overhauser-enhanced magnetic resonance elastography

Arnaud Comment, Najat Salameh

Magnetic resonance elastography (MRE) is a powerful technique to assess the mechanical properties of living tissue. However, it suffers from reduced sensitivity in regions with short T-2 and T-2* such as in tissue with high concentrations of paramagnetic i ...

Iron regulatory proteins and their role in controlling iron metabolism

Cellular iron homeostasis is regulated by post-transcriptional feedback mechanisms, which control the expression of proteins involved in iron uptake, release and storage. Two cytoplasmic proteins with mRNA-binding properties, iron regulatory proteins 1 and ...

Conditional Deletion of Ferritin H in Mice Reduces B and T Lymphocyte Populations

The immune system and iron availability are intimately linked as appropriate iron supply is needed for cell proliferation, while excess iron, as observed in hemochromatosis, may reduce subsets of lymphocytes. We have tested the effects of a ferritin H gene ...

A fast and reproducible method to quantify magnetic nanoparticle biodistribution

Heinrich Hofmann, Lionel André Maurizi, Usawadee Sakulkhu

The quantification of nanoparticles, particularly superparamagnetic iron oxide nanoparticles (SPIONs), both in vitro and in vivo has become highly important in recent years. Some methods, such as induced coupled plasma (ICP) spectroscopy and UV-visible che ...

Tracking Temperature-Dependent Relaxation Times of Ferritin Nanomagnets with a Wideband Quantum Spectrometer

Klaus Kern, Markus Ternes

We demonstrate the tracking of the spin dynamics of ensemble and individual magnetic ferritin proteins from cryogenic up to room temperature using the nitrogen-vacancy color center in diamond as a magnetic sensor. We employ different detection protocols to ...

Intestinal ferritin H is required for an accurate control of iron absorption

Lukas Kühn

To maintain appropriate body iron levels, iron absorption by the proximal duodenum is thought to be controlled by hepcidin, a polypeptide secreted by hepatocytes in response to high serum iron. Hepcidin limits basolateral iron efflux from the duodenal epit ...

Analysis of mice with conditional ferritin H deletion

Iron is a transitional metal required by virtually all organisms as a dietary micromineral, indispensable for cellular survival and proliferation. The management of iron absorption and distribution in the organism and inside the cell must be tightly regula ...

Conditional deletion of ferritin H in mice induces loss of iron storage and liver damage

Friedrich Beermann, Lukas Kühn

Ferritin plays a central role in iron metabolism by acting both as iron storage and detoxifying protein. We have generated a ferritin H allele with loxP sites and studied the conditional ferritin H deletion in adult mice. Ten days after Mx-Cre induced dele ...

Differential translational regulation of IRE-containing mRNAs in Drosophila melanogaster by endogenous IRP and a constitutive human IRP1 mutant

Lukas Kühn

Insects, like vertebrates, express iron regulatory proteins (IRPs) that may regulate proteins in cellular iron storage and energy metabolism. Two mRNAs, an unspliced form of ferritin H mRNA and succinate dehydrogenase subunit b (SDHb) mRNA, are known to co ...

To live and let die in The Big Blue

Karl Gademann

Harmful algal blooms in both freshwater and marine environments pose significant challenges for humans, livestock and aquatic food webs. Over the last 50 years, several authors proposed that small mol. iron chelators (siderophores) could be responsible for ...
