Abstract
This paper describes the synthesis and O2 binding properties of core-shell structured hemoglobin (Hb) nanoparticles (NPs), artificial O2 carriers of five types, as designed for use as red blood cell (RBC) substitutes. Human adult Hbs were polymerized using α-succinimidyl-ω-maleimide and dithiothreitol in spheroidal shapes to create parent particles. Subsequent covalent wrapping of the sphere with human serum albumin (HSA) yielded 100 nm-diameter Hb nanoparticles (HbNPs). The HbNP showed higher O2 affinity than that of RBC, but NPs prepared under a N2 atmosphere exhibited low O2 affinity. Entirely synthetic particles comprising recombinant human adult Hb and recombinant HSA were also fabricated. Using a recombinant Hb (rHb) variant in which Leu-β28 of the heme pocket had been replaced with Phe, we found somewhat low O2 affinity of rHb(βL28F)NP. Particles made of stroma-free Hb (SFHb) containing natural antioxidant enzyme catalase (SFHbNP) formed a very stable O2 complex, even in aqueous H2O2 solution. The SFHbNP showed good blood compatibility and did not affect the blood cell component functionality. The circulation half-life of SFHbNP in rats was considerably longer than that of naked Hb. All results indicate these Hb-based NPs as useful alternative materials for RBC and as a useful O2 therapeutic reagent in diverse medical scenarios.

Extracellular Vesicles Derived from Mesenchymal Stromal Cells Delivered during Hypothermic Oxygenated Machine Perfusion Repair Ischemic/Reperfusion Damage of Kidneys from Extended Criteria Donors. BIOLOGY 2022; 11:biology11030350.

Abstract
Simple Summary In this study, we explore for the first time an innovative tool for organ preservation aimed to preventing ischemia reperfusion injury (IRI) in marginal kidneys from expanded criteria donors (ECD) unsuitable for transplantation. Ex vivo hypothermic oxygenated perfusion (HOPE) with and without MSC-derived EV and normothermic reperfusion (NR) with artificial blood composed of bovine hemoglobin were applied on kidneys to evaluate global renal ischemic damage score, renal ultrastructure, mitochondrial distress, apoptosis, cell proliferation index, and the mediators of energy metabolism. Our study demonstrates that kidney conditioning with HOPE+EV arrests the ischemic damage, prevents reoxygenation-dependent injury, and preserves tissue integrity. EV delivery during HOPE can be considered a new organ preservation strategy to increase the donor pool and improving transplant outcome. The originality of our study lies an EV and HOPE combined novel setting use in kidneys from ECD, but also in any condition for graft dysfunction such as ischemia/reperfusion. Abstract The poor availability of kidney for transplantation has led to a search for new strategies to increase the donor pool. The main option is the use of organs from extended criteria donors. We evaluated the effects of hypothermic oxygenated perfusion (HOPE) with and without extracellular vesicles (EV) derived from mesenchymal stromal cells on ischemic/reperfusion injury of marginal kidneys unsuitable for transplantation. For normothermic reperfusion (NR), we used artificial blood as a substitute for red blood cells. We evaluated the global renal ischemic dam-age score (GRS), analyzed the renal ultrastructure (RU), cytochrome c oxidase (COX) IV-1 (a mitochondrial distress marker), and caspase-3 renal expression, the tubular cell proliferation index, hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) tissue levels, and effluent lactate and glucose levels. HOPE+EV kidneys had lower GRS and better RU, higher COX IV-1 expression and HGF and VEGF levels and lower caspase-3 expression than HOPE kidneys. During NR, HOPE+EV renal effluent had lower lactate release and higher glucose levels than HOPE renal effluent, suggesting that the gluconeogenesis system in HOPE+EV group was pre-served. In conclusion, EV delivery during HOPE can be considered a new organ preservation strategy for increasing the donor pool and improving transplant outcome.

Abstract
Zika virus (ZIKV) leads to congenital microcephaly and anomalies and severe neurological diseases such as Guillain-Barre syndrome. Safe and effective vaccines are necessitated to deal with these severe health threats. As an ideal antigen, the domain III of the envelope protein (EDIII) of ZIKV can evoke potent neutralizing antibodies without any antibody-dependent enhancement (ADE) effect. However, EDIII necessitates to be formulated with an antigen delivery system or adjuvants to improve its immunogenicity. Hemoglobin (Hb) regulates inflammation, cytokine levels, and activate macrophage. Mannan is a polysaccharide of the fungal cell wall with an immunomodulatory activity. In this study, EDIII was conjugated with Hb and mannan, using the disulfide bond as the linker. Hb and mannan both functioned as the adjuvants. Conjugation of Hb and mannan acted as the delivery system for EDIII. The structure of EDIII was essentially maintained upon conjugation of Hb and mannan. The intracellular release of EDIII from the conjugate (HM-EDIII-2) was achieved by reduction of the glutathione-sensitive disulfide bond. As compared with EDIII, HM-EDIII-2 elicited high EDIII-specific IgG titers and high levels of Th1-type cytokines (IFN-γ and IL-2) and Th2-type cytokines (IL-5 and IL-10), along with no apparent toxicity to the organs. Moreover, the pharmacokinetic study revealed a prolonged serum exposure of HM-EDIII-2 to the immune cells. Thus, HM-EDIII-2 could boost a strong humoral and cellular immune response to EDIII. Our study was expected to provide the feasibility necessary to develop a robust and potentially safe ZIKV vaccine.

Abstract
Hemoglobin-based oxygen carriers (HBOCs) are an investigational replacement for blood transfusions and are known to cause oxidative damage to tissues. To investigate the correlation between their oxygen binding properties and these detrimental effects, we investigated two PEGylated HBOCs endowed with different oxygen binding properties - but otherwise chemically identical - in a Guinea pig transfusion model. Plasma samples were analyzed for biochemical markers of inflammation, tissue damage and organ dysfunction; proteins and lipids of heart and kidney extracts were analyzed for markers of oxidative damage. Overall, both HBOCs produced higher oxidative stress in comparison to an auto-transfusion control group. Particularly, tissue 4-hydroxynonenal adducts, tissue malondialdehyde adducts and plasma 8-oxo-2'-deoxyguanosine exhibited significantly higher levels in comparison with the control group. For malondialdehyde adducts, a higher level in the renal tissue was observed for animals treated with the high-affinity HBOC, hinting at a correlation between the HBOCs oxygen binding properties and the oxidative stress they produce. Moreover, we found that the high-affinity HBOC produced greater tissue oxygenation in comparison with the low affinity one, possibly correlating with the higher oxidative stress it induced.

Abstract
Increasing the size of hemoglobin (Hb) by polymerization offers the benefits of reduced renal clearance and increased duration in the vascular circulation. With this goal, diaspirin cross-linked hemoglobin (DCLHb) was modified in order to keep one thiol group on the surface and then polymerized with 1,6-bismaleimic-hexane (1,6-BMH) to increase the molecular weight. The HPLC results indicated that approximate 20% dimers to tetramers of DCLHb desired were achieved after the polymerization. It was also demonstrated that the oxygen-carrying capacity of the products was similar to natural heme. The present study is expected to improve the efficacy of the DCLHb as an oxygen therapeutic agent.

Abstract
Persistent safety concerns have stalled the development of viable hemoglobin (Hb)-based oxygen carriers (HBOCs). HBOCs have several advantages over human blood, including availability, long-term storage, and lack of infectious risk. The basis of HBOC toxicity is poorly understood, however, several mechanisms have been suggested, including Hb extravasation across the blood vessel wall, scavenging of endothelial nitric oxide (NO), oversupply of oxygen, and heme-mediated oxidative side reactions. Although there are some in vitro and limited animal studies supporting these mechanisms, heme-mediated reactivity appears to provide an alternative path that can explain some of the observed pathophysiological changes. Moreover, recent mechanistic and animal studies support a role for globin and heme scavengers in controlling oxidative toxicity associated with Hb infusion.

Abstract
Sodium nitrite (NaNO(2)) was evaluated in a 55% EBV hemorrhage swine model to mitigate the increased blood pressure due to HBOC-201. Animals were resuscitated by three 10 ml/kg infusions of either HBOC-201 or Hextend with and without NaNO(2). All vital signs, coagulation and blood chemistry were measured for 2 hr. HBOC-201-vasoconstriction was attenuated only after the first 10.8 μmol/kg NaNO(2) infusion. Complete abolition was obtained with the highest 3 NaNO(2) dose, but side effects were observed. There was no reduction in platelet function due to NaNO(2). NaNO(2) ability to reduce HBOC-201 vasoactivity was transient and 10.8 μmol/kg NaNO(2) seems an acceptable dose for further investigation.

Pentacoordinate respiratory hemoproteins such as hemoglobin and myoglobin have evolved to supply cells with oxygen. However, these respiratory heme proteins are also known to function as redox enzymes, reacting with compounds such as nitric oxide and peroxides. The recent discoveries of hexacoordinate hemoglobins in vertebrates and nonsymbiotic plants suggest that the redox activity of globins is inherent to the molecule. The uncontrolled formation of radical species resulting from such redox chemistry on respiratory hemoproteins can lead to oxidative damage and cellular toxicity. In this review, we examine the functions of various globins and the mechanisms by which these globins act as redox enzymes under physiologic conditions. Evidence that redox reactions also occur under disease conditions, leading to pathologic complications, also is examined, focusing on recent discoveries showing that the ferryl oxidation state of these hemoproteins is present in these disease states in vivo. In addition, we review the latest advances in the understanding of globin redox mechanisms and how they might affect cellular signaling pathways and how they might be controlled therapeutically or, in the case of hemoglobin-based blood substitutes, through rational design.

Abstract
Recent setbacks in using Hb-based technology to develop oxygen carriers or blood substitutes may spur new and fundamentally different approaches for the development of a new generation of hemoglobin-based oxygen carriers (HBOCs). This article briefly details some underlying mechanisms that may have been responsible for the adverse-event profile associated with HBOCs, with a focus on the contribution of the author's laboratory toward identifying some of these biochemical pathways and some ways and means to control them. It is hoped that this will aid in the development of a safe and effective second generation of HBOCs.

Abstract
Hemoglobin-based oxygen carriers (HBOC) are currently being developed as red blood cell (RBC) substitutes for use in transfusion medicine. Despite significant commercial development, late stage clinical results of polymerized hemoglobin (PolyHb) solutions hamper development. We synthesized two types of PolyHbs with ultrahigh molecular weights: tense (T) state PolyHb (M(W)=16.59 MDa and P(50)=41 mmHg) and relaxed (R) state PolyHb (M(W)=26.33 MDa and P(50)=0.66 mmHg). By maintaining Hb in either the T- or R-state during the polymerization reaction, we were able to synthesize ultrahigh molecular weight PolyHbs in distinct quaternary states with no tetrameric Hb, high viscosity, low colloid osmotic pressure and the ability to maintain O(2) dissociation, CO association and NO dioxygenation reactions. The PolyHbs elicited some in vitro RBC aggregation that was less than 6% dextran (500 kDa) but more than 5% human serum albumin. In vitro, T-state PolybHb autoxidized faster than R-state PolybHb as expected from previously reported studies, conversely, when administered to guinea pigs as a 20% exchange transfusion, R-state PolybHb oxidized faster and to a greater extent than T-state PolybHb, suggesting a more complex oxidative processes in vivo. Our findings also demonstrate that T-state PolybHb exhibited a longer circulating half-life, slower clearance and longer systemic exposure time compared to R-state PolybHb.

Abstract
Hemoglobin (Hb) released into the circulation during hemolysis and chemically modified Hb proposed for use as oxygen therapeutics exert toxic effects that are partially attributable to heme's oxidant activity. Native extracellular Hb is scavenged by haptoglobin (Hp) after alphabeta-subunit dimerization. In the absence of Hp, monocyte/macrophage cell-surface CD163 binds and clears Hb. We evaluated several chemically modified Hbs to establish the role of chemical cross-linking patterns and molecular sizes on binding and clearance by each pathway. We found that Hbs possessing beta-globin cross-linking, irrespective of polymerization, demonstrate increased Hp affinity compared with alpha-globin-stabilized Hbs. These data suggest that Hb alpha-subunit accessibility is critical for Hp binding in the absence of dimerization. beta-Globin chain cross-linked tetramers/polymers displayed strong polyvalent Hp binding with increased viscosity and formation of visible gel matrices. Modified Hb interaction with CD163 and cellular uptake demonstrated an inverse relation with molecular size, irrespective of alpha and beta cross-linking. These findings were confirmed by HO-1 induction and intracellular ferritin accumulation in CD163-expressing HEK293 cells. Based on these results, a rational and systematic approach to HBOC design may be used to optimize interaction with endogenous Hb clearance and detoxification pathways.

Abstract
Chemically modified or recombinant hemoglobin (Hb)-based oxygen carriers (HBOCs) have been developed as oxygen therapeutics or 'blood substitutes' for use in a variety of clinical settings. Oxidative and nitrosative reactions of acellular Hb can limit the effectiveness and compromise the safety of HBOCs. The reactions between Hb and biologically relevant redox active molecules may also perturb redox sensitive signaling pathways. In recent years, systematic in vitro and in vivo structural and functional evaluation of several HBOCs has been carried out and, in some cases, delineated the 'structural' origin of their toxicity. This enables potential protective strategies against Hb-mediated side reactions to be rationally suggested. Here the authors provide an overview of their research experiences, novel insights into the molecular basis of toxicities of these products and some lessons learned.
