Plasma Heme Scavengers Alpha-1-Microglobulin and Hemopexin as Biomarkers in High-Risk Pregnancies

Frontiers in Physiology, 2019
Women with established preeclampsia (PE) have increased plasma concentration of free fetal hemoglobin. We measured two hemoglobin scavenger system proteins, hemopexin (Hpx) and alpha-1-microglobulin (A1M) in maternal plasma using enzyme-linked ...

Precision Medicine in Neurodegeneration with Brain Iron Accumulation (NBIA) Disorders: An Update on Emerging Treatments

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Neurodegeneration with Brain Iron Accumulation (NBIA) is a heterogeneous group of heritable, mostly recessive, progressive neurodegenerative diseases characterized by iron deposition in the basal ganglia and brainstem. There are no solid global epidemiological data on prevalence and incidence of NBIA subtypes, but registry data and ...

Hemopexin regulates acute-phase inflammatory response against pathogenetic infections in black rockfish (Sebastes schlegelii)

Comparative Immunology Reports
Hemopexin as an acute-phase protein binds heme with a high affinity and participates in a variety of processes of physiology and pathology. Hemopexin plays an important role in regulating inflammatory response by regulating pro-/anti-inflammatory ...

Host Iron Nutritional Immunity Induced by a Live Yersinia pestis Vaccine Strain Is Associated with Immediate Protection against Plague

Frontiers in Cellular and Infection Microbiology, 2017
Prompt and effective elicitation of protective immunity is highly relevant for cases of rapidly deteriorating fatal diseases, such as plague, which is caused by Yersinia pestis. Here, we assessed the potential of a live vaccine to induce rapid protection

Endothelial Barrier Integrity Is Disrupted In Vitro by Heme and by Serum From Sickle Cell Disease Patients

Frontiers in Immunology, 2020
Free extracellular heme has been shown to activate several compartments of innate immunity, acting as a danger-associated molecular pattern (DAMP) in hemolytic diseases.

Perinatal Metabolism of Hemopexin and Heme

Experimental Biology and Medicine, 1971
SummarySera from fetal, newborn, and juvenile rabbits were found to have lower Hx levels than those of their mothers but approached the normal adult range by 30 to 60 days of age. Inadequate materno-fetal transport of Hx contributed to low fetal and neonatal serum levels, since only small amounts of homologous 125I-Hx passed from the maternal ...

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Evaluation of Hemolysis Risk, Renal Function, and Safety Among Two Pulsed Field Ablation Systems: A Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Pentaspline systems were associated with more pronounced laboratory markers of hemolysis, although clinically significant renal dysfunction remained uncommon and evidence regarding clinical consequences remains limited. ABSTRACT This study investigated the hemolysis risk, renal, and safety outcomes between two pulsed field ablation (PFA) systems.
