Immune Modulating Qualities of Sorghum Polyphenols


 
 
 The objective was to evaluate the potential anti-inflammatory effects of Sorghum polyphenolic extracts on raw 264.7 cells.
 
 
 
 Sorghum polyphenols were extracted using a 70% ETOH and 5% citric acid solvent. Raw 264.7 cells were treated with either vehicle 1.25, or 0.625 mg/ml polyphenol extract from either a novel high polyphenol sorghum or SC84. Supernatant was harvested and Nitric Oxide was measured at a 12 hour time point. ELISA assay was performed to measure the concentrations of 12 anti-inflammatory associated cytokines. Cell morphology changes were observed at 3, 6, 12, and 24 hours using light microscopy. 84 genes associated with inflammation were measured via QPCR. Western blot analysis measured the expression of LC3 as well as STAT1, STAT3 and NF-kB nuclear translocation.
 
 
 
 Nitric Oxide was reduced by the sorghum extract (not significant). Cell morphology changed by  developing vacuole like structures and an apparent decrease in cell number. ELISA analysis showed that Il-6 and Il-10 were significantly reduced in all treatments. SC84 extract showed an increase in G-CSF production in activated macrophages. QPCR revealed LPS and IFNY activated cells treated with HP extract showed an increase in the expression of 9 and decreased expression of 14 cytokine related genes compared to cells that had only been activated by LPS and IFN Y. When LPS and IFN Y activated cells were cotreated with SC84 extract, 15 cytokine related genes were upregulated and 16 cytokine related genes were downregulated. LC3 expression was measured via western blot and showed a dose dependent with 1.25 mg/ml showing statistical significance. STAT3 nuclear translocation induce by LPS/IFN Y was attenuated by sorghum polyphenols.
 
 
 
 The sorghum polyphenols modulated immune response via a reduction in Th2 promoting cytokines IL-6 and IL-10. LC3 II expression increased with the concentration of the HP polyphenol extract treatment, suggesting autophagy.
