Figure 3From: Nasal lavage natural killer cell function is suppressed in smokers after live attenuated influenza virusCharacterization of NK Cells in the Nasal Lavage by Flow Cytometry. NK cells were identified in CD45+ NLF cell populations of nonsmokers at baseline. A) Representative flow cytometric plot depicting NK cells (CD56+) and neutrophils (CD56-CD16+). B) Percentages of total NK cells are greater than neutrophils in non-squamous NLF cell populations. C) Percentages of CD16- NK cells are greater than percentages of CD16+ NK cells in non-squamous NLF cell populations. **p < 0.01, * p < 0.05. Nonsmoker n = 11.Back to article page
