Introduction: Alzheimer disease is one of the brain functional disorder, which influenced on memorize and mental ability of patients, slowly. Interleukin-10 acts as an immune regulator in inflammatory situation. Also Interleukin 33 (IL-33) is a cytokine belonging to the IL-1 superfamily. IL-33 induces helper T cells, mast cells, eosinophils and basophils to produce type 2 cytokines. The Caffeic acid (3, 4- dihydroxy cinnamic acid) is one of the most importance of hydroxycinnamic acid in Propolis that its antioxidant effect could block NF-kappa B pathway
Methods: The present study was performed on wistar rat, these animals were divided into 6 groups (control, sham, scopolamine, 1, 3 and 8 Caffeic acid phenethyl ester recipients). The DNA was extracted from their brain tissue. Then IL-10 and IL 33 genes expression was evaluated by QRT-PCR. The histopathological examinations were performed on brain sections
Results: The number of remaining healthy neurons in the Caffeic acid phenethyl ester treated group 3 mg was more than the number of these cells in the treatment group with Caffeic acid phenethyl ester 1 mg. Although the highest number of normal cells were observed in sham group and treated with Caffeic acid phenethyl ester 8 mg. The molecular studies also showed that the expression level of IL-10 and IL-33 genes were significantly increased in the group treated with 3 mg drug.
Conclusion: Using an effective dose of Caffeic acid phenethyl ester, as an anti-inflammatory compound, can improve Alzheimer through impact on the IL-10 and IL-33 genes expression and the memory and learning improvement and reducing cellular damage. However, more extensive studies are still needed in this area
