Core Tip

Core tip:Acanthopanax senticosus polysaccharides (ASPS) effectively protect against gastric tight junction (TJ) injury in sepsis. ASPS pretreatment significantly improved intestinal histological appearance and gut permeability, increased electron dense between adjoining cells, sustained the expression and redistribution of occludin and zonula occludens-1, suppressed the expression of nuclear factor-kappa B p65 (NF-κBp65) and phospho-inhibitor kappa B-alpha and myosin light chain kinase (MLCK), as well as phospho-myosin light-chain-2 in endotoxemia. These findings suggest that ASPS pretreatment may be associated with inhibition of the NF-κB/MLCK pathway and concomitant amelioration of gastric TJ dysfunction in the mouse model of endotoxemia.
