Total ginsenosides from wild ginseng improve immune regulation in a rat model of spleen qi deficiency by modulating fecal-bacteria-associated short-chain fatty acids and intestinal barrier integrity
For thousands of years, traditional Chinese medicine (TCM) has made extensive use of wild ginseng. It is thought to provide vital energy effects and to boost immunity. This study aimed to clarify the processes by which short-chain fatty acids (SCFAs) metabolites and the intestinal barrier are used by total ginsenosides wild ginseng (TWG) to modulate immunity. In this study, we analyzed and identified ginsenosides in the colon using UPLC-Q-TOF-MS E methods. In the meantime, a rat model of spleen qi deficiency (SQD) was created using reserpine, and the effects of TWG on intestinal barrier function and short-chain fatty acids in the feces of SQD-affected rats were examined. 28 ginsenosides were found in the colon during this experiment, and the main components were measured. TWG considerably increased fecal concentrations of acetic, propionic and 6 others, according to SCFAs analysis. According to serum immunological markers, TWG reduced IL-17 and IL-1β levels, increased IL-10, IL-22, and TGF-β concentrations, balanced Th17/Treg ratios, and reduced toxicants such DAO and LPS in rats with SQD. TWG improved barrier function, reduced permeability, increased tight junction protein expression, and lessened intestinal injury. A favorable correlation between intestinal barrier proteins and fatty acids was shown by correlation studies. The gut barrier and SCFAs perspectives helped to clarify the mechanism by which TWG controls immune activity. This study offers a fresh theoretical framework for TWG's future advancement and application.
