Anti-inflammatory effects of Iturin A on the 6-OHDA-induced SH-SY5Y cell model of Parkinson’s disease
Abstract
Aim: Biosurfactants produced by bacteria are particularly important due to their antibacterial, antifungal, and antiviral properties, which offer therapeutic and biomedical potential. Nevertheless, no research has examined the impact of Bacillus-derived biosurfactant Iturin A on Parkinson's disease. This study examined the neuroprotection through cytokine modulation of Iturin A to formulate a novel therapeutic approach for Parkinson's disease.
Materials and Methods: The effect of Iturin A on cell viability in SH-SY5Y cells was evaluated by the [3-(4,5-Dimethyl thiazole-2) 2,5-diphenyltetrazolium bromide] method. As a result of this experiment, the non-toxic dose was determined by cell viability (%). To evaluate the neuroprotective effect of Iturin A, SH-SY5Y cells were treated with a non-toxic dose of Iturin A and then induced with 6-OHDA. After these treatments, cytokines (interleukin 6, transforming growth factor beta) and chemokine (interleukin 8) in SH-SY5Y cells were evaluated by ELISA kit. GraphPad Prism 9 was used to analyze all data.
Results: Using one-way ANOVA and Dunn's post hoc test, normally distributed data was tested for multiple comparisons. Treatment with Iturin A for 48 hours showed a neuroprotective effect on 6-hydroxy dopamine-induced SH-SY5Y cells by statistically significantly decreasing the expression levels of interleukin 6 (P<0.001), transforming growth factor beta (P<0.001), and interleukin 8 (P<0.0001).
Conclusion: Iturin A might offer new approaches to treating Parkinson's patients, and additional in vivo studies are necessary to confirm the in vitro results.
