Abstract | Background: Activation of NADPH oxidase is required for neutrophil extracellular trap (NET) formation. Protein kinase C (PKC) is an upstream mediator of NADPH oxidase activation and thus likely to have a role in NET formation. Methods: Pharmacological inhibitors were used to block PKC activity in neutrophils harvested from healthy donor blood. Results: Pan PKC inhibition with Ro-31-8220 (p<0.001), conventional PKC inhibition with Go 6976 (p<0.001) and specific PKCβ inhibition with LY333531 (p<0.01) blocked NET formation in response to PMA. Inhibition of novel and atypical PKC had no effect. LY333531 blocked NET induction by the diacylglycerol analogue OAG (conventional PKC activator) (p<0.001). Conclusions: Conventional PKCs have a prominent role in NET formation. Furthermore PKCβ is the major isoform implicated in NET formation. |
