Hyperferritinemia, an unclear mechanism, is frequently observed in chronic alcoholics. The aim of this work was to study the effect of alcohol on ferritin expression in a human hepatoblastoma cell line, HepG2. This cell line proved to be sensitive to alcohol, since alcohol increased gamma-GT activity both in cells and media. The most striking result was the increase of ferritin in cells and media by alcohol. Moreover, this effect was specific, since it contrasted with a decrease in total protein synthesis and secretion, a decrease in transferrin excretion and a lack of effect on orosomucoid. In our model, alcohol was able to induce, in a specific manner, ferritin expression.

Unraveling the inflammation-degeneration tangle in early MS: preliminary insights from ferritin, neurogranin, TREM2, and retinal ganglion cell layer.

Background: Multiple sclerosis (MS) involves a complex interplay between immune-mediated inflammation and neurodegeneration. Recent advances in biomarker research have provided new insights into the molecular underpinnings of MS, including ferritin, neurogranin, Triggering Receptor Expressed on Myeloid cells 2 (TREM2), and neurofilaments light chain.
Objectives: This pilot study aims to investigate the levels of these biomarkers in the cerebrospinal fluid (CSF) of MS patients and explore their associations with clinical, cognitive, and optical coherence tomography (OCT) parameters.

Large-scale studies indicate a strong relationship between the gut microbiome, type 2 diabetes mellitus (T2DM), and atherosclerotic cardiovascular disease (ASCVD). Here, a higher abundance of the type III secretion system (T3SS) virulence factors of Enterobacteriaceae/Escherichia-Shigella in patients with T2DM-related-ASCVD, which correlates with their atherosclerotic stenosis is reported. Overexpression of T3SS via Citrobacter rodentium (CR) infection in Apoe-/- T2DM mice exacerbated atherosclerotic lesion formation and increased gut permeability.

Single-cell sequencing of lineage negative (Lin-) cells from patients with myelodysplastic syndromes (MDS) revealed a reduction in ferritin heavy chain 1 (FTH1) levels, yet the significance of this decrease in FTH1 in the pathophysiology of MDS remains unclear. In this study, we evaluated the role of FTH1 in patients with MDS. The mRNA expression of FTH1 in GlycoA nucleated erythrocytes from MDS patients was significantly lower than that in control group.

Aplastic Anemia (AA) is one of the life-threatening bone marrow failure syndromes. One of the main pathologies of AA is reduced erythropoietic activity evidenced by decreased soluble transferrin receptor (sTfR) levels which results in minimal iron utilization and accumulation of iron in tissues in the form of ferritin. This study aimed to measure serum level of sTfR in adult AA patients and correlate it with the severity of the disease and the response to treatment.

Background: Patients with transfusion-dependent thalassemia experience iron dysregulation, which affects the immune response. Surface proteins such as FcγRIII (CD16), lipopolysaccharide receptor (CD14), and human leukocyte antigen (HLA-DR) on monocytes are crucial for innate and adaptive responses. Blood monocytes, identified by their CD14 and CD16 expression, show functional diversity during injury or inflammation.
