The secretion of HMGB1 is required for the migration of maturing dendritic cells.
myeloid DC, which rapidly secrete upon maturation induction their own HMGB1, remodel their actin-based cytoskeleton, up-regulate the CCR7 and the CXCR4 chemokine receptors, and acquire the ability to migrate in response to chemokine receptor ligands. The events are apparently causally related: DC challenged with LPS in the presence of HMGB1-specific antibodies fail to up-regulate the expression of the CCR7 and CXCR4 receptors and to rearrange actin-rich structures. Moreover, DC matured in the presence of anti-HMGB1 antibodies fail to migrate in response to the CCR7 ligand CCL19 and to the CXCR4 ligand CXCL12
