Purified human monocytes that had been treated for 5 hours with AHCC FD at high (AHCC FD-H, 500 μg/ml) or low (AHCC FD-L, 100 μg/ml) concentrations, LPS (100 ng/ml) or vehicle control were added to autologous memory CD4+ T cells. Cells were then cultured for 7 days in the presence of anti-CD3 and –CD28 antibodies. Culture supernatants were collected and analyzed for IL-17, IFN-γ and IL-13 by multiplex cytokine assay. Bars and error bars indicate mean (n = 8) and standard error of mean, respectively. *P < 0.05.
