A 12-week exercise program induces a decreased fold change of CCR5⁺ cDC upon LPS and IFN-γ stimulation and an increased fold change of HLA-DR⁺ pDC upon IQ stimulation.

Blood samples were stimulated overnight with LPS in combination with IFN-γ, or IQ. The percentage of CCR5, CD86, and HLA-DR positive cDC and pDC after TLR stimulation was measured using flow cytometry. Mean fold changes are calculated as the ratio of the proportion of CCR5, CD86, and HLA-DR positive cDC and pDC in the stimulated condition to the nonstimulated condition. Results are shown as mean fold change ± SEM.

cDC, conventional dendritic cells; pDC, plasmacytoid dendritic cells; LPS, lipopolysaccharide; IQ, imiquimod; EX, exercise group; SED, sedentary group; PRE, baseline measurement; POST, measurement after 12 weeks; SEM, standard error of the mean.
