520 |a C5a plays a central role in antineutrophil cytoplasmic antibody (ANCA)-mediated neutrophil recruitment and activation. A previous study showed that C5a played a crucial role in the regulation of high mobility group box 1 (HMGB1) release from human neutrophils. The current study further investigated the interaction between C5a and HMGB1 in ANCA-induced neutrophil activation. The effects of HMGB1 inhibitors on the translocation of ANCA antigens, ANCA-induced respiratory burst and degranulation of C5a-primed neutrophils were tested. We found that blocking HMGB1 decreased C5a-mediated translocation of ANCA antigens, as well as ANCA-induced respiratory burst and degranulation of C5a-primed neutrophils. Further study showed that supernatant of C5a-primed neutrophils, which contained HMGB1, also caused translocation of ANCA antigens of primary neutrophils, whereas blocking HMGB1 decreased the translocation. In conclusion, blocking HMGB1 may attenuate ANCA-induced activation of C5a-primed neutrophils. The interaction between HMGB1 and C5a might play an important role in ANCA-induced neutrophil activation
