Abstract:

The presence of Th17 cells in CNS lesion of MS patients due to their inflammatory cytokines secretion is in line with the deterioration of the disease. Currently, the use of natural compounds with anti-inflammatory properties such as flavonoids have been considered to reduce inflammation in these patients, but the remaining issue is how deliver these compounds to the site of inflammation. Acetylation is a way to better uptake compound by cells and cross through cellular layers with tight junctions. This study aimed to investigate theeffects of the Apigenin 3-Acetate on Th17 cells of MS patients and compare its efficacy with Apigenin and Methyl Prednisolone Acetate.IC50 for Apigenin 3-Acetate, and Methyl Prednisolone Acetate were determined using three healthy volunteers. The peripheral blood mononuclear cells (PBMCs) of five MS patients were isolated and co-cultured with a selected dose of Apigenin, Apigenin 3-Acetate, and Methyl Prednisolone Acetate for 48 hr, and then theproliferation of Th17 cells in isolated PBMCs was assessed by flow cytometry. The levels of RAR-related orphan receptor (RORC) and IL-17A expression were also determined by quantitative real-time PCR.The results showed that Apigenin 3-Acetate inhibited Th17 cells proliferation (P value: 0.018) at 80µM concentration after 48 hr. Additionally, IL-17A gene expression significantly (P value≤ 0.0001) inhibited by Apigenin, Apigenin 3-Acetate and Methyl Prednisolone Acetate in 80 µM, 80 µM and 2.5 µM (selected dose in IC50 determination) respectively These results demonstrate that Acetate increases anti-inflammatory effects of Apigenin on Th17 cells.
