Representative graphs from individual subjects tracking percentages of CD4+ and CD8+ T cells during stable and exacerbation visits. Peripheral blood was collected during stable visits and during AE-COPD, prior to medication. Cells were stained and analyzed by flow cytometry. Panels a-e each depicted the data for a single subject; CD4+ T cells (upper panels, blue) and CD8+ T cells (lower panels, red) shown as a percentage of all CD45+ leukocytes. a, b. Two subjects with multiple AE-COPD; c, d. two subjects with a single AE-COPD; and e, subject with no AE-COPD. Stable visits are shown by open circles and AE-COPD are shown in solid circles labeled with “Ex”
