Use of polypeptides obtained through systematic mutations of single amino acids of human and non-human Box-A of HMGB1 to prevent and/or antagonize pathologies induced by HMGB1

摘要

The present invention relates to polypeptide variants of the HMGB-1 high affinity binding domain Box-A (HMGB1 Box-A) or to a biologically active fragment of HMGB1 Box-A, which are obtained through systematic mutations of single amino acids of the wild-type HMGB1 Box-A protein and which show an increased resistance to proteases and which are therefore characterized by more favourable pharmacokinetic and pharmacodynamic profiles. Moreover, the present invention concerns the use of said polypeptide molecules of HMGB1 Box-A to diagnose, prevent, alleviate and/or treat pathologies associated with extracellular HMGB1 and associated with RAGE.
