Structural divergence of lentinula edodes polysaccharides is associated with distinct anti-hyperuricemia pathways.

ABSTRACT: Lentinula edodes (L. edodes) polysaccharides hold therapeutic potential for hyperuricemia (HUA), but their mechanisms remain unclear. This study investigated the anti-HUA effects and associated regulatory pathways of two structurally distinct polysaccharides (LEP20 and LEP50) from L. edodes. Structural analysis identified LEP20 as a (1 → 3)-β-D-glucan (M_w, 1.96×10⁶g/mol) and LEP50 as a (1 → 4)-α-D-glucan (M_w, 1.46×10⁷g/mol). In a HUA rat model, both LEP20 and LEP50 significantly reduced serum UA level, inhibited xanthine oxidase, and alleviated renal injury and inflammation. Mechanistically, LEP20 was linked to modulate the gut-kidney axis by regulating UA transporters, enriching beneficial gut microbiota (e.g., Blautia_luti), and promoting sho
