Abstract:

Objective

To explore the role of colony-stimulating factor-1(CSF-1) and 1,25(OH)2D3 in macrophage proliferation and polarization and their impact on the formation of calcium oxalate kidney stones.

Methods

Fifteen 8-week-old male CSF-1-deficient C57 mice were randomly divided into three groups: a control group, a CSF-1 induction group, and a 1,25(OH)2D3+CSF-1 intervention group. Bone marrow macrophages from each group of mice were cultured. Optical microscopy, flow cytometry, and quantitative real-time polymerase chain reaction were used to detect the number of macrophages and the expression levels of CD206 and CSF-1 receptor mRNA in each group.

Results

The CSF-1 group significantly increased the number of macrophages and the expression of the M2 marker CD206. Although the combined treatment with 1,25(OH)2D3 and CSF-1 had a synergistic effect, it was less effective than the CSF-1 induction group.

Conclusion

1,25(OH)2D3 and CSF-1 play significant roles in regulating macrophage proliferation and polarization towards the M2 type, and there is an interrelationship between them, which provides a new research direction for the immunomodulation of calcium oxalate kidney stones.
