Mean fluorescence intensity (MFI) of cellular expression of (a) CD11b, (b) CD63 and (c) CD66b, on PMNs isolated from controls (n = 16) and periodontitis subjects (n = 19). PMNs were gated according to CD16 expression and the sideward scatter profile. Expressions of surface markers of interest were corrected for the non-specific binding of the isotype control antibodies. Data are mean ± SD. *Comparisons periodontitis group versus control group, Student’s T-test, *P = 0.024. ^#Comparisons oPMN versus cPMN within subjects, paired T-test, all ^#P < 0.001
