PARPs metabolize NAD and catalyze protein ADP-ribosylation to potentiate the pro-inflammatory response by co-activating NFκB signal or by repressing the anti-inflammatory function of sirtuins in NAD-dependent or independent ways (54, 55), leading to the development of chronic inflammation and acute multiple organ failures of septic shock (56–58). Here, NFKB1 is linked to Shock.
