High Mobility Group Box 1 (HMGB1) is a highly conserved nuclear protein that functions as an alarmin when released extracellularly. Initially discovered as a DNA-binding protein involved in transcription regulation, HMGB1 has been recognized as a critical damage-associated molecular pattern (DAMP) molecule that mediates sterile inflammation following tissue injury. In the central nervous system, HMGB1 plays complex roles in neuroinflammation, neurodegeneration, and neural repair.
