Intracellular IFN-γ expression from stimulated human PBMC upon extract treatment. Cells were stimulated with a mixture of SARS-CoV-2 S peptide pool, PMA, and ionomycin, and treated with the extracts for 6 hours. Brefeldin A was used to enhance intracellular cytokine staining signals. Representative scattergrams of intracellular IFN-γ staining without (a) and after (b) stimulation are given. Bars are means + SD of at least three independent experiments. and . Significance of difference was calculated relative to the respective solvent control by one-way ANOVA.
