WebFeb 12, 2014 · HMGB1 with C23 and C45 in a disulfide bond signals via TLR4, eliciting the release of proinflammatory cytokines. Complete reduction of cysteines to thiols abrogates the cytokine-stimulating activity; it induces autophagy via RAGE. Thiol HMGB1-complexed CXCL12 serves as a chemoattractant and induces cell migration.
WebJun 22, 2015 · During inflammation, high-mobility group box 1 in reduced all-thiol form (at-HMGB1) takes charge of chemoattractant activity, whereas only disulfide-HMGB1 (ds-HMGB1) has cytokine activity. WebDifferential gene expression analysis showed all-thiol HMGB1-driven upregulation of a number of prominent pro-inflammatory markers including Il1α and Il1β. Interestingly, conditioned plasma had a more profound effect on the CB transcriptome resulting in inhibition rather than activation of the immune-related pathways. These data are the first ...
WebFeb 27, 2013 · All-thiol HMGB1 is a potent chemotactic mediator. The redox state requirements for HMGB1 to induce its potent chemotactic activity to recruit neutrophils and monocytes to inflammatory sites have been recently clarified to be distinctly different than those required for the cytokine-inducing activity .
