  2. Neutrophil oxidative index - Wikipedia

    en.wikipedia.org/wiki/Neutrophil_Oxidative_Index

    Neutrophil oxidative burst test (or chronic granulomatous disease (CGD) test) is a measure of neutrophil oxidation and is a useful assay in the diagnosis of chronic granulomatous disease and is also a useful means to determine the overall metabolic integrity of phagocytosing neutrophils. The NADPH oxidase enzyme is missing in CGD. From total ...

  3. Myeloperoxidase - Wikipedia

    en.wikipedia.org/wiki/Myeloperoxidase

    Myeloperoxidase (MPO) is a peroxidase enzyme that in humans is encoded by the MPO gene on chromosome 17. [5] MPO is most abundantly expressed in neutrophils (a subtype of white blood cells), and produces hypohalous acids to carry out their antimicrobial activity, including hypochlorous acid, the sodium salt of which is the chemical in bleach.

  4. Myeloperoxidase deficiency - Wikipedia

    en.wikipedia.org/wiki/Myeloperoxidase_deficiency

    Myeloperoxidase deficiency is a disorder featuring lack in either the quantity or the function of myeloperoxidase–an iron-containing protein expressed primarily in neutrophil granules. [1] [2] [3] There are two types of myeloperoxidase deficiency: primary/inherited and secondary/acquired. [4]

  5. NADPH oxidase - Wikipedia

    en.wikipedia.org/wiki/NADPH_oxidase

    NADPH oxidase (nicotinamide adenine dinucleotide phosphate oxidase) is a membrane-bound enzyme complex that faces the extracellular space. It can be found in the plasma membrane as well as in the membranes of phagosomes used by neutrophil white blood cells to engulf microorganisms.

  6. Respiratory burst - Wikipedia

    en.wikipedia.org/wiki/Respiratory_burst

    Most notably, oxidative burst post fertilisation can be seen in the sea urchin egg. This is believed to be evolutionally divergent from that in neutrophils. Hydrogen peroxide is produced by egg oxidase activity following an increase in oxygen consumption. [19] This is essential for the cross-linking of the ovum proteins to prevent lethal ...

  7. Red blood cell indices - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell_indices

    The reticulocyte production index (RPI) or corrected reticulocyte count (CRC) represents the true significance of the absolute reticulocyte count to provide some reflection of erythropoietic demand and supply. The immature reticulocyte fraction (IRF) goes a step further to cast more light on the same question. [citation needed]

  8. N-Formylmethionine-leucyl-phenylalanine - Wikipedia

    en.wikipedia.org/wiki/N-Formylmethionine-leucyl...

    [7] fMLF and a sampling of other, less potent, N-formyl oligopeptides were then found to stimulate a wide array of rabbit neutrophil functions such as: the transient auto-aggregation of these cells in suspension [11] and equally transient fall in circulating neutrophils when injected into rabbit veins (these responses result from an increase in ...

  9. Nitro blue tetrazolium chloride - Wikipedia

    en.wikipedia.org/wiki/Nitro_blue_tetrazolium...

    Nitro blue tetrazolium is used in a diagnostic test, [3] particularly for chronic granulomatous disease and other diseases of phagocyte function. When there is an NADPH oxidase defect, the phagocyte is unable to make reactive oxygen species or radicals required for bacterial killing. As a result, bacteria may thrive within the phagocyte.
