HMGB1 (High-Mobility Group Box-1) is a nuclear protein that acts as an architectural chromatin-binding factor involved in the maintenance of nucleosome structure and regulation of gene transcription. It can be released into the extracellular milieu from immune and non-immune cells in response to various stimuli. Extracellular HMGB1 contributes to the pathogenesis of numerous chronic inflammatory and autoimmune diseases, including sepsis, rheumatoid arthritis, atherosclerosis, chronic kidney disease, systemic lupus erythematosus (SLE), as well as cancer pathogenesis. Interaction of released HMGB1 with the cell-surface receptor for advanced glycation end products (RAGE) is one of the main signaling pathways triggering these diseases. It has been also demonstrated that the inhibition of the HMGB1-RAGE interaction represents a promising approach for the modulation of the inflammatory and tumor-facilitating activity of HMGB1.
