Figure 1From: Targeting peripheral blood pro-inflammatory cytotoxic lymphocytes by inhibiting CD137 expression: novel potential treatment for COPD CD28nullCD8- (clear bars) and CD28nullCD8+ NKT-like cells (grey bars) in 10 control subjects (N) and 14 patients with COPD (C). Data presented as box plots. There was a significant increase in the percentage of CD28null/CD8+ NKT-like cells in patients with COPD compared with control subjects but no change in CD28null/CD8- NKT-like cells between groups.Back to article page
