Figure 6

Cytotoxic activity of CD56 + cells in the presence of different concentrations of an anti-perforin antibody (A), an anti-granzyme B antibody (B) and a combination of the two (C) from HNS (n = 3), smokers (n = 3) and COPD subjects (n = 3). Immunomagnetically selected CD56+ cells were incubated with the stated concentration of antibody and used at the effector:target ratio of 5:1 against K562 cells in the LDH release cytotoxicity assay.
