Recruitment and activation of NK cells in B16 metastases-bearing lungs of mice treated with CpG-ODN/Poly(I:C) aerosol combined with dacarbazine. Percentage and representative dot plots of NK cells, evaluated as DX5+ cells gated on FSClowSSClowCD45+CD3- cells (A), and of CD69+ (B) and NKG2D+ (C) NK cells, gated on DX5+ cells, obtained by enzymatic digestion of B16 metastases-bearing lungs of mice (4 mice/group) treated with aerosol CpG-ODN/Poly(I:C), DTIC, aerosol CpG-ODN/Poly(I:C) plus DTIC or left untreated. Percentage and representative dot plots of degranulating NK cells, evaluated as CD107a+ cells gated on CD45+CD3-DX5+ cells, after co-culture with B16 melanoma cells (D), and of CFSE-labeled B16 dead cells, evaluated as 7AAD+ cells gated on CFSE+ cells, after co-culture with cells obtained from lung enzymatic digestion (E). *p < 0.05, ***p < 0.001.
