Immunomodulatory Effects of Sodium Hyaluronate Health Drink on Immunosuppressed Mice.

This study aimed to explore the immunomodulatory effects and mechanism of a sodium hyaluronate health drink in immunosuppressed mice. The results showed that the sodium hyaluronate health drink could improve thymus atrophy, repair spleen cell damage, promote the release of IL-2, IL-6 and TNF-α in serum, restore immune deficiency, and enhance immune function. In addition, 16s rRNA sequencing results of intestinal flora showed that different doses of health drink had different effects on the intestinal flora of mice. The low-dose group of mice showed a significant up-regulation of the abundance of Lactobacillus and promoted the formation of a new genus Akkermansia, while the medium- and high-dose group up-regulated the abundance of Lactobacillus and norank-f-Muribaculaceae, and stimulated the production of the new genus Alistipes. Sodium hyaluronate health drink may enhance the immune function of mice by changing the composition and abundance of intestinal flora, which provided a theoretical basis for the subsequent product development.
