There was a lower percentage of effector Th1 cells (CXCR3+/CX3CR1−) and a higher percentage of terminally differentiated Th1 cells (CXCR3+/CX3CR1+) and vascular homing cells (CXCR3−/CX3CR1+) in CKD+PD groups versus control (Figure 4D). This evidence concerns the gene CX3CR1 and chronic kidney disease.
