Fig. 4From: A systems biology approach to investigating the influence of exercise and fitness on the composition of leukocytes in peripheral bloodImmunophenotypic differences in sedentary versus active individuals at baseline samples. Immunophenotypes were measured by flow cytometry from baseline samples from 10 active subjects and 5 sedentary subjects. a CD45RO+ and PD-1+ cells were measured as a percent of parent CD4+ or CD8+ T cells in sedentary and active subjects. All subjects were included on the %CD45RO+ versus %PD-1+ plot. b Representative dot plots showing the distribution of positive and negative T cells for CD45RO and PD-1 (CD4 T cells on top, CD8 T cells on bottom.) The graph shows the percent positive PD-1 cells on memory T cells (CD45RO+) or naĆÆve T cells (CD45ROā) for both CD4 and CD8. **ā=āpā<ā0.001 by a paired T testBack to article page
