Abstract
The effect of â-Casomorphin-7 on intestinal mucosal immunity was investigated in aged mice. Mice were treated without or with different doses of â-Casomorphin-7 for 30 days. All mice were sacrificed and intestinal mucosa samples collection at the end of the experiment. Histopathological studies showed the tissue protective role of â-Casomorphin-7 in aged mice. The number of duodenal and jejunal epithelial lymphocytes decreased significantly Pandlt;0.05 The doses of duodenal and jejunal epithelial lymphocytes in mice were significantly Pandlt;0.05 increased in each dose group. The relative expression of TLR4,TRAF6 and NF-êB in the intestinal mucosa of the elderly model group was lower than that of the young control group. The low and middle dose groups significantly Pandlt;0.05 up-regulated the relative expression of TLR4, TRAF6 and NF-êB.The results suggest that â-Casomorphin-7 can improved intestinal mucosal immune decline likely through balancing TLR4\NF-êB signaling pathway.
