Abstract

The balance of arginine metabolism via nitric oxide synthase (NOS) or arginase is an important determinant of the inflammatory response of murine macrophages and dendritic cells. Here we analyzed the expression of the isoform arginase I in human myeloid cells. Using healthy donors and patients with arginase I deficiency, we found that in human leukocytes arginase I is constitutively expressed only in granulocytes and is not modulated by a variety of proinflammatory and anti-inflammatory stimuli in vitro. We demonstrate that arginase I is localized in azurophil granules of neutrophils and constitutes a novel antimicrobial effector pathway, likely through arginine depletion in the phagolysosome. Our findings demonstrate important differences between murine and human leukocytes with respect to regulation and function of arginine metabolism via arginase.

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.
