ABSTRACT
Objective:
To explore molecule mechanism about anti-aging of bifidobacterium by investigating the effect of lipoteichoic acid (LTA) of bifidobacterium on thymus of aging mice induced by D-galactose.Methods:
Male Kunming mice were divided into different groups at random. These mice were induced aging by subcutaneous injection of D-galactose on the back of mice and LTA was simultaneously administered to them daily for 40 days. Body weight, thymus index ,thymus morphology, thymus c-fos, p16 production and peripheral blood IL-2 concentration were tested by HE staining, immunochemistry method, ELISA and other methods.Results:
There were significant differences for body weight ,thymus index, thymus morphology,thymus p16, c-fos production and peripheral blood IL-2 concentration between the young control group and the aging model group. Whereas, LTA can improve thymus morphology ,increase body weight ,thymus index and c-fos production, meamwhile, decrease thymus p16 and peripheral blood IL-2 concentration of aging model mice.Conclusion:
The results showed that LTA can remarkably delay thymus aging, and it may be a molecular mechanism of bifidobacterium delaying immunosenescent.
