The level of surface CD11b expression on CF-PMNs did not correlate with the amount of mRNA present in CF-PMNs in either group (p = 0.056, 0.07 for control and periodontitis patients, respectively).
Mac-1-positive macrophages and the inflammatory gene expressions were significantly increased in periodontitis in GIPRKO compared with C57BL/C mice periodontitis.
Dissimilar to CD11b-positive cells, CD3-positive cells in the Peri+FTY group were lower in peripheral blood as well as furcation than the Peri group (p < 0.05).
All three activation markers were more expressed on the oPMNs compared to the cPMNs (p < 0.05), and a higher expression of CD11b on the oPMNs from periodontitis patients was observed compared to the control subjects (P = 0.024).
