AMD3100 is a small molecule inhibitor of chemokine receptor type 4 (CXCR4), which
is located in the cell membranes of CD34+ cells and a variety of inflammatory
cells and has been reported to reduce organ fibrosis in the lung, liver and
myocardium. However, the effect of AMD3100 on renal fibrosis is unknown. This
study investigated the impact of AMD3100 on renal fibrosis. C57bl/6 mice were
subjected to unilateral ureteral obstruction (UUO) surgery with or without
AMD3100 administration. Tubular injury, collagen deposition and fibrosis were
detected and analyzed by histological staining, immunocytochemistry and Western
Blot. Bone marrow derived pro-angiogenic cells (CD45+, CD34+ and CD309+ cells)
and capillary density (CD31+) were measured by flow cytometry (FACS) and
immunofluorescence (IF). Inflammatory cells, chemotactic factors and T cell
proliferation were characterized. We found that AMD3100 treatment did not
alleviate renal fibrosis but, rather, increased tissue damage and renal fibrosis.
Continuous AMD3100 administration did not improve bone marrow derived
pro-angiogenic cells mobilization but, rather, inhibited the migration of bone
marrow derived pro-angiogenic cells into the fibrotic kidney. Additionally, T
cell infiltration was significantly increased in AMD3100-treated kidneys compared
to un-treated kidneys. Thus, treatment of UUO mice with AMD3100 led to an
increase in T cell infiltration, suggesting that AMD3100 aggravated renal
fibrosis.
