Potential of HMGB-inhibitory oligodeoxynucleotide ISM ODN to neutrophil recruitment in mouse model of hepatitis

Genes Cells. 2023 Mar;28(3):202-210. doi: 10.1111/gtc.13002. Epub 2022 Dec 27.

Abstract

High-mobility group box 1 (HMGB1) is a nucleotide-binding chromatin protein that has also been characterized as a prototypical damage-associate molecular pattern. It triggers inflammatory responses upon release from damaged or dying cells. In fact, HMGB1 has been linked to the induction of many inflammatory diseases through immune cell activation including neutrophil recruitment. In this study, we examined the impact of HMGB1-binding inhibitory oligodeoxynucleotide (ISM ODN) on the development of hepatitis using a murine model of the disease. Our results indicate that ISM ODN effectively suppresses pathological features of hepatitis, including neutrophil accumulation. This study therefore may offer clinical insight into the treatment of hepatitis and possibly other inflammatory diseases.
