Bone marrow-derived Ly6C^- macrophages promote ischemia-induced chronic kidney disease.

ABSTRACT: Macrophages play an important role in renal injury and repair after acute kidney injury (AKI) and the subsequent chronic kidney disease (CKD) that often results. However, as macrophages have a high degree of plasticity and heterogeneity, the function(s) of macrophage subtypes in AKI-to-CKD progression are not fully understood. Here, we focused on Ly6C^- macrophages, which are derived from the embryonic yolk sac and post-development become resident in the kidneys. We found that C-C chemokine receptor type 2 (CCR2) deficiency, which blocks the migration of Ly6C⁺ macrophages from the bone marrow to the sites of injury, alleviated ischemia-induced AKI in mice. Unexpectedly, though, CCR2 deficiency worsened the subsequent renal fibrosis, which was marked by notable intra-re
