Figure 1From: Lymphocyte senescence in COPD is associated with loss of glucocorticoid receptor expression by pro-inflammatory/cytotoxic lymphocytes The percentage of CD28+ and CD28null CD8+ (clear bars) and CD8- T cells expressing Pgp1 in patients with COPD. Data presented as box plots. There was no significant change in the percentage of Pgp1+ CD8 + CD28null and CD8 + CD28+ or CD8-CD28null and CD8-CD28+ T cells in patients with COPD (p > 0.05 for all).Back to article page
