BoxA is an antagonist for HMGB1 and appears to inhibit all its activities, depending from all receptors. Injection of 600 µg BoxA in the mouse protects against sepsis in a peritonitis model and from hepatitis in a mouse model of HBV infection (Sitia et al 2007). BoxA (10 µg/mL) inhibits maturation, survival and Th1 differentiation of dendritic cells and T cell proliferation.It contains only trace amounts of LPS (<0.4 ng/mg protein), and it is tested for the ability to inhibit the chemotactic activity of HMGB1 on fibroblasts.

背景
BoxA is one of the highly conserved DNA binding domains of HMGB1 protein. It consists of 89 amino acids and has a calculated molecular mass of approximately 10.4 kDa. The sequence of BoxA is totally identical in human and mouse.
