WebFPN and SLC30A10 have been reported as two of the most important membrane proteins that transport metal ions out from cytoplasm. 25,38 To investigate the metabolic fate of Mn-IONPs in cells further, we analyzed the mRNA levels of FPN and SLC30A10 in the labeled cells. Both FPN and SLC30A10 were overexpressed in the first 24 hours (Figure 6C and D). Web21 sep. 2024 · Systematic low iron level influenced by hepcidin resulted in suppressed NK cell activation and downregulated IFN-γ ... (DMT1). Ferrous iron in intestinal epithelia cells is exported by ferroportin (FPN) and then is oxidized via hephaestin. Upon being transported by TfR1 and endosomes in the cytoplasm, iron may affect T-cell ...
