A Eight out of 44 SGs (18.18%) upregulated in CKD were found in M1 macrophage polarization dataset; and six out of 44 SGs (13.64%) upregulated in CKD were found in M2 macrophage polarization. 15 out of 121 SGs (12.4%) upregulated in ESRD were found in M1 macrophage polarization dataset; 16 out of 121 SGs (13.2%) were found in M2 macrophage polarization. These results suggest that macrophage polarization pathways participate CKD-, and ESRD-upregulated secretomic changes in the PBMCs in patients with CKD and ESRD (PMID: 30827512).
