However, research regarding its effects on gut flora and <jats:italic>in vivo<\/jats:italic> immunomodulation is insufficient.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>In this study, cyclophosphamide was administered to mice to establish an immunosuppressed mouse model. The regulatory effects of <jats:italic>Sibiraea laevigata maxim<\/jats:italic> polysaccharides (SLMPs) on immunity and intestinal microbiota in the immunosuppressed mouse model were investigated. The results indicated that SLMPs could mitigate spleen and thymus damage, protect immune organs, increase the levels of leukocytes, lymphocytes, neutrophils and monocytes in mouse blood and upregulate the levels of IL\u20102, IFN\u2010<jats:italic>\u03b3<\/jats:italic>, TNF\u2010<jats:italic>\u03b1<\/jats:italic> and IgA in mouse serum. Furthermore, SLMPs can restore intestinal microbial imbalance and enhance the diversity of gut microorganisms in immunosuppressed mice.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>The findings from this study indicated that SLMPs could enhance immunity and improve the structure and abundance of intestinal flora in mice. These results provide a theoretical basis for the further development and utilization of SLMPs in immunomodulatory adjuvants and functional foods, thereby promoting their application in these fields.
