Figure 3From: Non-typeable Haemophilus influenzae decreases cilia beating via protein kinase C epsilonNTHi supernatant fails to activate PKCϵ if it is heat-inactivated or frozen. A) Heat inactivation of the NTHi for 5 minutes at 95°C blocks the stimulation of PKCϵ at 10 min and 1 hr (*p < 0.05) (n = 6). PMA is included as a positive control for PKCϵ activation. B) Freeze-thawing the NTHi supernatant blocks the stimulation of PKCϵ (*p < 0.05) at 10 min and 1 hr (n = 6).Back to article page
