Background: Synthetic nanoparticles are deemed to improve treatment with the least adverse effects. The effect of Selenium Nanoparticles (SeNPs) was reviewed on various pathogenic disorders. In the present project, the role of SeNPs on macrophage responses was assessed.
Materials and Methods: SeNPs were prepared synthetically by ascorbic acid. Macrophages (MQs) were cultured and treated with SeNPs in combination with bladder tumor lysate and Bacillus Calmette Guerin (BCG). Other experimental groups include SeNPs + tumor lysate + MQs, BCG, BCG+MQs, and MQs. The mRNA levels of interferon-γ and interleukin-10 were evaluated using the real-time PCR method.
Results: Synthetic selenium nanoparticles combined with the tumor lysate upregulated the mRNA level of interferon-γ after 12 and 24 h treatment. Regarding interleukin-10 expression, there were no remarkable differences in all experimental groups. The maximum effect of synthetic SeNPs was observed after 24 h treatment.
Conclusion: The optimum effect of synthetic SeNPs presents in a treatment-dependent manner.
