High-mobility group box 1 protein (HMGB1) operates as an alarmin outside as well as inside cells.

Alarmins are preformed, endogenous molecules that can be promptly released to signal cell or tissue stress or damage. The ubiquitous nuclear molecule high-mobility group box 1 protein (HMGB1) is a prototypical alarmin activating innate immunity. HMGB1 serves a dual alarmin function. The protein can be emitted to alert adjacent cells about endangered homeostasis of the HMGB1-releasing cell. In addition to this expected path of an alarmin, extracellular HMGB1 can be internalized via RAGE-receptor mediated endocytosis to the endolysosomal compartment while attached to other extracellular proinflammatory molecules. The endocytosed HMGB1 may subsequently destabilize lysosomal membranes. The HMGB1-bound partner molecules depend on the HMGB1-mediated transport and the induced lysosomal leakage to obtain access to endosomal and cytosolic reciprocal sensors to communicate extracellular threat and to initiate the proper activation pathways.
