WebDec 23, 2024 · RAGE is a transmembrane receptor whose activation plays an important role in mediating pro-inflammatory responses. 25 HMGB1 interacts with RAGE to increase the permeability and rupture of the lysosome membrane, activate and release cathepsin B, 8 which directly activates NLRP3 through the leucine-rich repeat (LRR) domain of NLRP3, … WebDespite medical advances, neurological recovery after severe traumatic brain injury (TBI) remains poor. Elevated levels of high mobility group box protein-1 (HMGB1) are associated with poor outcomes; likely via interaction with receptors for advanced-glycation-end-products (RAGE). We examined the hypothesis that HMGB1 post-TBI is anti-neurogenic and …

WebApr 11, 2024 · HMGB1 binds several extracellular receptors, with the receptors for advanced glycation end products (RAGE) and Toll-like receptors (TLR) being the most studied . HMGB1 activates macrophages and dendritic cells to release TNF-α and produce inflammatory cytokines and chemokines via the TLR4/MD2/MyD88/NFκB pathway [ 103 ]. WebMar 8, 2024 · The co-expression of HMGB1 and RAGE is associated with the invasive and metastatic potential of hepatocellular carcinoma (22–24). In normal human bronchial epithelial cells, the HMGB1-induced inflammatory response promotes the activities of the RAGE/c-Jun N-terminal kinase 1 (JNK)/NF-κB pathway by binding to RAGE ( 25 , 26 ).
WebHMGB1 also act as DNA nuclear binding protein that has recently been shown to be an early trigger of sterile inflammation in animal models of trauma-hemorrhage via the activation of the Toll-like receptor 4 (TLR4) and the receptor for the advanced glycation endproducts (RAGE). Moreover, HMGB1 is reported that the level of HMGB1 is elevated ... Next, we investigated how the HMGB1 was loaded into the EVs and released into the extracellular space. First, we observed that the RAGE was co-localized with the endosome system (EEA1, Rab5, and Rab7).
