Although the deleterious vasoconstrictive effects of cell-free, hemoglobin-based blood substitutes have been appreciated, the systemic effects of chronic hemolysis on nitric oxide bioavailability have not been considered or quantified. Central to this investigation is the understanding that nitric oxide reacts at least 1,000 times more rapidly with free hemoglobin solutions than with erythrocytes. We hypothesized that decompartmentalization of hemoglobin into plasma would divert nitric oxide… Expand
Computation of plasma hemoglobin nitric oxide scavenging in hemolytic anemias.
TLDR
The paradigm that cell-free hemoglobin released into plasma during intravascular hemolysis in human disease contributes to the experimentally observed reduction in NO bioavailability and endothelial dysfunction is supported. Expand
The potential of Angeli's salt to decrease nitric oxide scavenging by plasma hemoglobin.
TLDR
It is shown that nitroxyl generated by Angeli's salt preferentially reacts with cell-free hemoglobin compared to that encapsulated in the red blood cell under physiologically relevant conditions, supporting the notion that Angeli’s salt or a similar compound could be used to effectively treat conditions associated with intravascular hemolysis.

The biochemistry of nitric oxide, nitrite, and hemoglobin: role in blood flow regulation.
TLDR
The newly described role of hemoglobin as a nitrite reductase is discussed in the context of blood flow regulation, oxygen sensing, and nitrite-based therapeutics. Expand
Sickle cell disease vasculopathy: a state of nitric oxide resistance.
TLDR
Human physiological and transgenic animal studies provide experimental evidence of cardiovascular and pulmonary resistance to NO donors and reduced NO bioavailability that is associated with vasoconstriction, decreased blood flow, platelet activation, increased endothelin-1 expression, and end-organ injury. Expand
An emerging role for nitric oxide in sickle cell disease vascular homeostasis and therapy
TLDR
The combined effects of inhaled nitric oxide gas of improving pulmonary ventilation to perfusion matching and hemodynamics, reducing alveolar and systemic inflammation, and inhibiting circulating plasma hemoglobin may modulate the course of the disease, including the frequency and severity of vaso-occlusive crises and acute chest syndrome episodes.

TLDR
Therapies directed at decreasing the destruction of nitric oxide, increasing the production of nitrous oxide, or amplifying the nitricoxide response may prove beneficial in sickle cell disease. Expand

TLDR
This review will discuss the proposed mechanisms for initiation and regulation of hypoxic pulmonary vasoconstriction by red blood cells with an emphasis on hemoglobin-NO interactions and how biologic (S-nitrosation) or pharmacologic (cross-linking) modification of hemoglobin may affect pulmonary circulatory-hemoglobin interactions.

TLDR
Data support the existence of a novel mechanism of human disease, hemolysis associated endothelial dysfunction, that potentially participates in the vasculopathy of iatrogenic and hereditary hemolytic conditions and may deliver NO as the hemoglobin deoxygenates. Expand
Nitric oxide pathology and therapeutics in sickle cell disease.
TLDR
Low NO bioavailability contributes to pathology in sickle cell disease and its restoration could serve as an effective treatment, and particular "NO donating" agents such as nitrite, which unlike some other NO donors can improve sickle RBC properties, may yet prove effective. Expand
Nitric oxide from nitrite reduction by hemoglobin in the plasma and erythrocytes.
TLDR
A multicellular model is constructed to characterize the amount of NO delivered by the reaction of nitrite with both intraerythrocytic and cell-free hemoglobin, while intentionally neglecting all other possible sources of NO in the vasculature. Expand

Inhaled nitric oxide augments nitric oxide transport on sickle cell hemoglobin without affecting oxygen affinity.
TLDR
The levels of nitrosylated hemoglobin are too low to affect overall hemoglobin oxygen affinity, but augmented NO transport to the microvasculature seems a promising strategy for improving microvascular perfusion. Expand
Nitric oxide reaction with red blood cells and hemoglobin under heterogeneous conditions
Understanding the interaction of nitric oxide (NO) with red blood cells (RBCs) is vital to elucidating the metabolic fate of NO in the vasculature. Because hemoglobin (Hb) is the most abundantExpand
Modulation of nitric oxide bioavailability by erythrocytes
TLDR
It is suggested that RBC membrane and cytoskeleton associated NO-inert proteins provide a barrier for NO diffusion and thus account for the reduction in the NO uptake rate of RBCs. Expand
Rate of reaction with nitric oxide determines the hypertensive effect of cell-free hemoglobin
TLDR
The results suggest that the rapid reactions of oxy- and deoxyhemoglobin with nitric oxide are the fundamental cause of the hypertension and Hemoglobins with decreased NO-scavenging activity may be more suitable for certain therapeutic applications than those that cause depletion of Nitric oxide. Expand
Intravascular flow decreases erythrocyte consumption of nitric oxide.
TLDR
It is shown that physiological concentrations of RBCs in the presence of intravascular flow does not inhibit NO-mediated vessel dilation, suggesting that R BCs under this condition are not an NO scavenger. Expand

TLDR
Transfusion with cell-free, bovine crosslinked hemoglobin in cats can selective reductions in blood flow in the intestines, kidneys, and adrenal glands without evidence of renal dysfunction by a mechanism consistent with nitric oxide scavenging. Expand
Mechanism of NO-induced oxidation of myoglobin and hemoglobin.
TLDR
The results provide a protein engineering strategy for reducing hypertensive events caused by extracellular hemoglobin-based O2 carriers by examining the effects of Phe(B10) and Phe (E11) substitutions on the rates of NO-induced oxidation of the alpha and beta subunits in recombinant human hemoglobin.

Relative role of heme nitrosylation and beta-cysteine 93 nitrosation in the transport and metabolism of nitric oxide by hemoglobin in the human circulation.
TLDR
The results demonstrate that NO-heme reaction pathways predominate in vivo, NO binding to heme groups is a rapidly reversible process, and S-nitrosohemoglobin formation is probably not a primary transport mechanism for NO but may facilitate NO release from heme. Expand
Effects of inhaled nitric oxide on regional blood flow are consistent with intravascular nitric oxide delivery.
TLDR
Results indicate that inhaled NO during blockade of regional NO synthesis can supply intravascular NO to maintain normal vascular function, and this effect may have application for the treatment of diseases characterized by endothelial dysfunction. Expand
