Techniques such as flow cytometry and immunofluorescence were employed to demonstrate that APS can inhibit the transition of renal macrophages to the M1 phenotype in RIAKI. Furthermore, the raw264.7 macrophage cell line was chosen and induced into the M1 phenotype to further examine the impact of APS on this model and elucidate the underlying mechanism.Results: Administration of APS led to a significant decrease in UREA levels by 25.2% and CREA levels by 60.9% within the model group. Also, APS exhibited an inhibitory effect on the infiltration of M1 macrophages and the cGAS-STING pathway in kidneys within the RIAKI, subsequently leading to decreased serum concentrations of IL-1β, IL-6 and TNF-α by 44.5%, 12.9%, and 10.3%, respectively, consistent with the results of in vitro experiments. Furthermore, APS exhibited an anti-apoptotic effect on MPC5 cells when co-cultured with M1 macrophages.Conclusion: Astragalus polysaccharide (APS) potentially mitigated rhabdomyolysis-induced renal damage by impeding the M1 polarization of macrophages. This inherent mechanism might involve the suppression of the cGAS-STING pathway activation within macrophages. Furthermore, APS could endow protective effects on podocytes through the inhibition of apoptosis.Keywords: astragalus polysaccharide, macrophages, rhabdomyolysis-induced acute kidney injury, cGAS-STING pathway |
