The chemokine receptors CCR2 and CX3CR1 mediate monocyte/macrophage trafficking in kidney ischemia–reperfusion injury
Open accessAbstract
Chemokines and their receptors such as CCR2 and CX3CR1 mediate leukocyte adhesion and migration into injured tissue. To further define mechanisms of monocyte trafficking during kidney injury we identified two groups of F4/80-positive cells (F4/80low and F4/80high) in the normal mouse kidney that phenotypically correspond to macrophages and dendritic cells, respectively. Following ischemia and 3 h of reperfusion, there was a large influx of F4/80low inflamed monocytes, but not dendritic cells, into the kidney. These monocytes produced TNF-α, IL-6, IL-1 α and IL-12. Ischemic injury induced in CCR2−/− mice or in CCR2+/+ mice, made chimeric with CCR2−/− bone marrow, resulted in lower plasma creatinine levels and their kidneys had fewer infiltrated F4/80low macrophages compared to control mice. CX3CR1 expression contributed to monocyte recruitment into inflamed kidneys, as ischemic injury in CX3CR1−/− mice was reduced, with fewer F4/80low macrophages than controls. Monocytes transferred from CCR2+/+ or CX3CR1+/− mice migrated into reperfused kidneys better than monocytes from either CCR2−/− or CX3CR1−/− mice. Adoptive transfer of monocytes from CCR2+/+ mice, but not CCR2−/− mice, reversed the protective effect in CCR2−/− mice following ischemia-reperfusion. Egress of CD11b+Ly6Chigh monocytes from blood into inflamed kidneys was CCR2- and CX3CR1-dependent. Our study shows that inflamed monocyte migration, through CCR2- and CX3CR1-dependent mechanisms, plays a critical role in kidney injury following ischemia reperfusion.

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.
