On page 17849 in Fig. 2B, the Western blot for HMGB1 release in the −DHIQ parp-1−/− panel was inadvertently duplicated in the +DHIQ WT panel during preparation of the final figure. The duplicated panel has been replaced with the correct photomicrograph, and the corrected figure is shown below. The correction does not affect the conclusions of the work.
