The expression of CCR2 and CX3CR1 in monocyte subsets. A. The MFI of CCR2 and CX3CR1 from monocyte subsets in young participants was analyzed by flow cytometry. Histograms were created using FlowJo software. B. Boxplots showing the MFI of CCR2 and CX3CR1 from monocyte subsets in young, middle-aged, and older individuals (young: 21–40 years, n = 23; middle-aged: 41–60 years, n = 15; older: > 60 years, n = 44). P-values were calculated using the non-parametric Kruskal–Wallis rank test, followed by post hoc analysis
