Circulating CD56^bright NK cells from HPV16(+) subjects with CIN showed a reduced ability to secrete IFN-γ. A Statistical graph displays percentage of IFN-γ created by CD56^dim and CD56^bright NK cells in the HPV16(+) women with different CIN grades and HPV(−) women. B Statistical graph displays percentage of TNF-α created by CD56^dim and CD56^bright NK cells in the HPV16(+) women with different CIN grades and HPV(−) women. C Representative dot plots of IFN-γ and TNF-α created by CD56^bright NK cells in the HPV(−) CIN 0 group and HPV16(+) CIN II–III groups
