Abstract

Nitrite was once thought to have little physiological relevance. However, nitrite is now being increasingly recognized as a therapeutic or possibly even physiological precursor of nitric oxide (NO) that is utilized when needed to increase blood flow. It is likely that different mechanisms for nitrite bioconversion occur in different tissues, but in the vascular system, there is evidence that erythrocyte haemoglobin (Hb) is responsible for the oxygen-dependent reduction of nitrite to modulate blood flow. Here, we review the complex chemical interactions of Hb and nitrite and discuss evidence supporting its role in vasodilation. We also discuss ongoing work focused on defining the precise mechanisms for export of NO activity from red blood cells and of other pathways that may mediate nitrite-dependent vasodilation.

  • The relative contribution of either mechanism to NO formation is likely to vary with oxygen partial pressure along the vascular tree.

    “The relative contribution of either mechanism to NO formation is likely to vary with oxygen partial pressure along the vascular tree [86,87].”

    From On the chemical biology of the nitrite/sulfide interaction (2015) · cites this paper as [86]

  • Several proposed mechanisms explain how nitrite-derived bioactivity can be exported from the red blood cell, generally involving either a compartment model with submembrane localization or formation of another nitrogen oxide such as a nitrosothiol or N2O3.

    “Several proposed mechanisms have been constructed to explain how nitrite-derived bioactivity can be exported from the red blood cell and these generally involve either a compartment model with submembrane localization of the reaction allowing for inefficient free NO escape, or the formation of another nitrogen oxide such as a nitrosothiol or N2O3 that can get out of the red blood cell and carry NO”

    From Mechanisms of nitrite bioactivation (2014) · cites this paper as [53]

  • Evidence for nitrite reactions with erythrocytic hemoglobin and stimulation of hypoxic blood flow remains more limited and is the subject of much debate.

    “The evidence for nitrite reactions with erythrocytic hemoglobin and stimulation of hypoxic blood flow remains more limited and is the subject of much debate [16, 61].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
