Eosinophils play a crucial role as effector cells in asthma pathogenesis, with their differentiation being tightly regulated by metabolic mechanisms. While the involvement of iron in various cellular processes is well known, its specific role in eosinophil differentiation has largely remained unexplored. This study demonstrates that iron levels are increased during the differentiation process from eosinophil progenitors to mature and activated eosinophils in the context of allergic airway inflammation.

These metal-herbicide interactions have inevitable but remarkable effects on insects, which remain poorly understood. Here, we examined the effects of the interactions among zinc (Zn), iron (Fe), and paraquat (PQ) at a sublethal dose on the physiological response of the Egyptian cotton leafworm .

Two billion people worldwide suffer from anemia, which can lead to the onset of cardiac disorders; nevertheless, the precise mechanisms remain unclear. There are at least three distinct mechanisms by which iron deficiency (ID) contributes to the development of cardiac disorders. First, ID increases concentrations of intact fibroblast growth factor-23 (iFGF-23), which promotes left ventricular hypertrophy.

Bacterial interspecies interactions shape microbial communities and influence the progression of polymicrobial infections. FemI-FemR-FemA, a cell-surface signaling system, in , is involved in the uptake of iron-chelating mycobactin produced by spp. In this report, we present the data that indicates the -PA1909 operon is positively regulated by ExsA, a master regulator for the type three secretion system (T3SS), connecting the Fem system with T3SS.

School of Agricultural Engineering and Food Science, Shandong University of Technology, Zibo 255049, Shandong, PR China. Electronic address:
Fe-loaded red radish anthocyanin (RRA) and zein composite nanoparticles (FZNPs) were firstly prepared to enhance the color and stability of RRA. The addition of Fe caused anthocyanin to form color chelates, enhancing its pH color sensitivity. The prepared FZNPs showed good stability and anthocyanin retention during long-term storage.
