LC/MS Analysis of Phosphorylated Protein Changes in Mouse Brain Tissue After LPS Treatment and Angong Niuhuang Wan Administration

Introduction: Angong Niuhuang Wan (AGNHW), developed in the Qing dynasty (18th century) for treating consciousness disturbances caused by severe infections, has already been used to treat brain edema caused by ischemia-reperfusion. However, it remains unclear whether AGNHW can ameliorate vascular-origin brain edema caused by lipopolysaccharides (LPS).This study explores the ameliorative effects of AGNHW on cerebrovascular edema in mice caused by LPS, as well as its potential mechanisms.Mice were divided into four groups: Control, LPS 26 h, LPS 48 h, and LPS + AGNHW_M. Enriched phosphorylated peptides were extracted from mouse brain tissues at the corresponding time points and subjected to phosphoproteomic analysis.
