PTX3 and IL15 gene expression in peripheral blood mononuclear cells by RT-PCR in chronic kidney disease (CKD) and hemodialysis (HD) patients. Dot-plot represents PTX3 and IL15 gene expression assessed by RT-PCR in PBMC from 9 CKD and 17 HD patients. The bars indicate the median value. As depicted, HD patients showed significantly higher level of both genes compared to CKD patients. P values were calculated by t-test.
