After 8\u2010week interventions with low\u2010 and high\u2010dose PCP, we systematically evaluated the therapeutic efficacy by measuring the levels of autoantibodies, the expression of inflammatory cytokines, and renal function\u2010related parameters. Finally, 16S rDNA gut microbiome sequencing with metabolomics analysis was used to explore the pharmacological mechanism of PCP intervention in LN. PCP could reverse the phenotype of MRL\/lpr mice, reduce autoantibody levels, alleviate inflammatory responses, and improve renal function. Gut microbiome analysis found that PCP can improve gut microbiota composition and abundance of two phyla (\n                    <jats:italic>Firmicutes<\/jats:italic>\n                    ,\n                    <jats:italic>Bacteroidota<\/jats:italic>\n                    ) and five genera (\n                    <jats:italic>Lachnospiraceae<\/jats:italic>\n                    NK4A136 group,\n                    <jats:italic>Alistipes<\/jats:italic>\n                    ,\n                    <jats:italic>Butyricicoccus<\/jats:italic>\n                    ,\n                    <jats:italic>Bacteroides<\/jats:italic>\n                    ,\n                    <jats:italic>Lactobacillus<\/jats:italic>\n                    ), which play an important role in the process of PCP intervention on metabolism in MRL\/lpr mice. UHPLC\u2013MS untargeted metabolomics showed that PCP significantly affects multiple key differential metabolites, including Linoleic acid, L\u2010Phenylalanine, L\u2010Tyrosine, and 56 other metabolites. These metabolites are primarily involved in metabolic pathways such as tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, tyrosine metabolism, linoleic acid metabolism, and arachidonic acid metabolism. Correlation analysis between gut microbiota and differential metabolites reveals a close relationship, suggesting that gut microbiota promoting host metabolism may be one of the mechanisms by which PCP treats LN. PCP alleviates LN by modulating the \u201cmicrobiota\u2010metabolism axis,\u201d reducing autoantibodies, inflammation, and renal damage, while reshaping gut microbiota and regulating key metabolic pathways.\n
