Pgp1+ T, NKT-like and NK cells producing IFNγ, TNFα and Granzyme b in COPD and control subjects. Data presented as box plots. a. There was a significant increase in IFNγ expression by Pgp1+ T, NKT-like and NK cells in COPD patients compared with controls. b. There was a significant increase in TNFα expression by Pgp1+ T, NKT-like and NK cells in COPD patients compared with controls. c. There was a significant increase in granzyme b expression by Pgp1+ T, NKT-like and NK cells in COPD patients compared with controls.
