Popis: Objective (s): Silver nanoparticles (NPs) have attracted considerable attention owing to their important properties, including antimicrobial and anti-oxidative stress effects. However, high concentrations of silver NPs have been reported to have toxic effects. The present study aimed to evaluate the modulatory and protective effects of royal jelly (RJ) against the harmful effects of silver NPs on hippocampal functions, such as learning and memory. Materials and Methods: This experimental study was conducted on 40 male Wistar rats. The animals were divided into four groups of 10, including the control group (no silver NPs and RJ), RJ group, silver NPs plus RJ, and silver NPs. Some functions of the hippocampus (e.g., learning and memory) were evaluated using Morris memory function tests for four consecutive days. In addition, the relative expression of TRPV1 was assessed using real-time polymerase chain reaction (RT-PCR). At the final stage, hippocampal tissues were collected for histological studies.Results: Levels of learning and memory, relative gene expression ratio of TRPV1, and the histological changes in the hippocampus were significantly different in the groups receiving silver NPs compared to the groups administered with RJ. Conclusion: According to the results, RJ may be the effective in the protection against the adverse effects of silver NPs and improve the function of the hippocampus.
