Background:The immune system is a crucial component of the defense against viral infections. Some cytokines are directly involved in regulating the immune response by suppressing viral replication. Interleukin-6 (IL-6) is a pleiotropic cytokine that plays a crucial role in regulating the biological responses of several target cells to viral infections. Natural compounds such as anthocyanin possess antiviral properties that are potentially beneficial in various viral infections. The aims of This study is to analyze the effect of anthocyanins on the expression of the cytokine IL-6 in PBMC cell cultures infected with the Hepatitis B virus.
Methods: This study was an in-vitro experimental study. This study used a control group and a treatment group, with 18 PBMC cell culture wells. The treatment involved adding 50 µL of purple sweet potato water extract with an anthocyanin content of 0.01575 µg/µL in RPMI1640 culture medium for 24 hours into PBMC culture wells. The effect on the IL-6 cytokine response was measured by measuring IL-6 mRNA expression extracted from RNA isolated from PMBC cell culture samples using the quantitative real timePCR method and interpolarization using a serial dilution standard curve cycle threshold. Data analysis was performed using statistical analysis.
Results: Statistical analysis of the effects of purple sweet potato extract exposure on the treatment and control groups was carried out using a paired t-test, showing that there was an effect of exposure to purple sweet potato extract on IL-6 mRNA expression in the treatment group with a p value of 0.001 (p<0.05), while no significant effect of exposure to purple sweet potato extract was found in the control group with a p value of 0.420 (p>0.05). The results of the independent t-test statistical analysis showed that in the treatment group, the mean difference in IL-6 mRNA expression was -75.87±45.77 fg/µL, while in the control group, it was -49.26±173.70 fg/µL. In the treatment group and the control group, the mean difference in IL-6 mRNA expression was -26.61 fg/µL with a p value of 0.66 (p>0.05).
Conclusion:This study showed that anthocyanins in purple sweet potato water extract did not significantly increase IL-6 mRNA expression in HBV-infected PBMC cultures compared to controls.
