From: Altered effector function of peripheral cytotoxic cells in COPD
Correlation of cytotoxic activity and lung function in NK (CD56 + CD3 - ) cells (Panel A) and NKT-like (CD56 + CD3 + ) cells (Panel B) in COPD subjects. Immunomagnetically separated cells (25,000) were cultured with K562 cells (5,000) giving an effector:target ratio of 5:1, in an LDH release cytotoxicity assay compared to FEV1 (% pred).
