A novel role for HMGB1 in TLR9-mediated inflammatory responses to CpG-DNA
5 Jun 2007
Abstract excerpt
CpG-DNA or its synthetic analog CpG-ODN activates innate immunity through Toll-like receptor 9 (TLR9). However, the mechanism of TLR9 activation by CpG-DNA remains elusive. Here we have identified HMGB1 as a CpG-ODN-binding protein. HMGB1 interacts and preassociates with TLR9 in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC), and hastens TLR9's redistribution to early endosomes in response to...
