Alhagi honey polysaccharide (AHPN), a bioactive macromolecule with a molecular weight of 9.35 \u00d7 10\u0142 Da primarily composed of mannose (29.384%), glucose (41.804%), and galactose (28.810%), represents a promising candidate for antifibrotic therapy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This study established a carbon tetrachloride (CCl\n                      <jats:sub>4<\/jats:sub>\n                      )-induced liver fibrosis mouse model to evaluate AHPN\u2019s intervention effect. Liver injury, collagen deposition, and fibrosis progression were assessed histologically and biochemically. The underlying mechanisms were explored through analysis of the TGF-\u03b21\/Smad3 signaling pathway, hepatic stellate cell activation, Nrf2\/HO-1 antioxidant pathway, inflammatory cytokine profiles, and fibrosis marker expression. Additionally, 16S rDNA sequencing and metabolomics were employed to investigate AHPN\u2019s regulatory effects on gut microbiota composition and hepatic metabolism.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      AHPN administration significantly attenuated hepatic injury, reduced collagen deposition, and suppressed fibrosis progression by inhibiting TGF-\u03b21\/Smad3 signaling and hepatic stellate cell activation, accompanied by restored liver function. Mechanistically, AHPN activated the Nrf2\/HO-1 pathway to alleviate oxidative stress, decreased serum levels of pro-inflammatory cytokines (IL-6, IL-1\u03b2, TNF-\u03b1), and downregulated fibrosis-related markers (\u03b1-SMA, collagen I, LN, PCIII, IV-C). Notably, 16S rDNA sequencing revealed that AHPN enriched beneficial gut bacteria including\n                      <jats:italic>Bacteroidaceae<\/jats:italic>\n                      ,\n                      <jats:italic>Lactobacillaceae<\/jats:italic>\n                      , and\n                      <jats:italic>Marinifilaceae<\/jats:italic>\n                      while restoring intestinal tight junction proteins (Occludin, ZO-1).
