ABSTRACT
OBJECTIVE To observe the anti-aging effects of SOD mimicAEOL-10150 in anti-senescence accelerated mouse resistant 1 (SAMR1) strain. METHODS The lifespan of SAMR1 mice were observed by subcutaneous injection AEOL-101502 mg·kg- 1 once a week. Morris water maze, new object recognition, nesting and forced swimming were used to observe the behavioral changes of animals. Lymphocyte subgroups and ROS were measured by Flow cytometry. The cytokines levels were determined by Luminex method. The number of DCX + neurons in brain tissue was observed by immunofluorescence. RESULTS The results showed that AEOL-10150 could prolong the mean lifespan of SAMR1 mice, but it had no obvious effect on maximal lifespan. What's more, AEOL-10150 could significantly improve the spatial learning memory of aged mice, but it could not increase the number of DCX+ neurons in the hypothalamic MBH and hippocampal DG regions. Then, we observed the effects of AEOL-10150 on peripheral blood lymphocyte subgroups and cytokines. We found that AEOL-10150 significantly modulated the lymphocyte subgroups and cytokine release. Especially, AEOL-10150 can dose-dependently inhibit plasma levels of SASP related inflammatory cytokines TNF-α and IL-17. CONCLUSION The results indicate that AEOL-10150 has anti-aging effects, and the effects are closely related to modulating immunity and inhibiting SASP production.
