Sepsis, also known as systemic inflammatory response syndrome, is a
life-threatening condition caused by a pathogenic agent and leading to multiple
organ dysfunction syndrome. One of the factors responsible for the excessive
intensification of the inflammatory response in the course of inflammation is
high-mobility group protein B1 (HMGB1). HMG-1 is a nuclear protein which, after
being released to the intercellular space, has a highly pro-inflammatory effect
and acts as a late mediator of lethal damage. The purpose of this study was to
examine whether the anti-inflammatory action of riboflavin is accompanied by
inhibition of HMGB1 release during peritoneal inflammation and zymosan
stimulation of macrophages. Peritonitis was induced in male BALB/c and C57BL/6J
mice via intraperitoneal injection of zymosan (40 mg/kg). RAW 264.7 macrophages
were activated with zymosan (250 µg/ml). Riboflavin (mice, 50 mg/kg; RAW 264.7,
25 µg/ml) was administered 30 min before zymosan, simultaneously with, or 2, 4,
6 h after zymosan. Additionally, mRNA expression of HMGB1 and its intracellular
and serum levels were evaluated. The research showed that riboflavin
significantly reduces both the expression and the release of HMGB1; however, the
effect of riboflavin was time-dependent. The greatest efficacy was found when
riboflavin was given 30 min prior to zymosan, and also 2 and 4 h (C57BL/6J; RAW
264.7) or 4 and 6 h (BALB/c) after zymosan. Research showed that riboflavin
influences the level of HMGB1 released in the course of inflammation; however,
further study is necessary to determine its mechanisms of action.
