Regulation of NAMPT protein levels, as analyzed by ELISA.

Group	NAMPT (ng/106 cells)
	24 h	48 h
Control	0.66 ± 0.10	0.65 ± 0.07
IL-1β	5.85 ± 0.77*	7.27 ± 1.09*
P. gingivalis	14.35 ± 3.01*	14.99 ± 2.37*
F. nucleatum	17.00 ± 2.87*	8.86 ± 1.28*

NAMPT protein levels in supernatants from IL-1β-, P. gingivalis-, and F. nucleatum-stimulated HGF (6 donors) at 24 h and 48 h. Untreated cells served as control. Mean ± SEM; *significantly (P < 0.05) different from control.
