HMGB1 redox kinetics. (A) Short-term (left) and long-term (right) changes of HMGB1 redox status upon LPS stimulation. Western blot showing the All-thiol-H (all-thiol-HMGB1) or Disulfide-H (disulfide-HMGB1) expression in BMDM whole-cell lysates, which was treated with LPS (100 ng/mL) for indicated times. Methods were used as our previous study (38). (B) HMGB1 secretion timeframe. Disulfide-H from culture supernatant was measured by Western blot. (C) Graphical representation of the relationship between HMGB1 oxidation (left y-axis, closed circle) quantified as % maximum from (A) and HMGB1 secretion (right y-axis, opened circle). The level of secreted HMGB1 was determined by ELISA (38).
