WebBoth high mobility group box-1 (HMGB1) and histones are major damage-associated molecular patterns (DAPMs) that mediate lethal systemic inflammation, activation of the complement and coagulation system, endothelial injury and multiple organ dysfunction syndrome in critical illnesses. WebFeb 18, 2024 · Histones can serve as damage-associated molecular pattern (DAMP) molecules involved in downstream amplification of inflammation through toll-like receptors (TLR) and other mediators. Thus, the proinflammatory and cytotoxic nature of circulating histones can result in tissue injury across various organ systems [ 6 ].
WebHistones are positively charged nuclear proteins that facilitate packaging of DNA into nucleosomes common to all eukaryotic cells. Upon cell injury or cell signalling processes, histones are released passively through cell necrosis or actively from immune cells as part of extracellular traps.
