Fig. 1From: Effects of polyphenols and lipids from Pennisetum glaucum grains on T-cell activation: modulation of Ca2+ and ERK1/ERK2 signalingEffect of PGL and PGPC on T cell proliferation. The cells (5 × 105 cells/ml) were stimulated with different concentrations of the extracts as described in Methods. Cell number were determined with a hemocytometer. Inserts show the stimulation index (SI) of T-cell proliferation in response to PGL (left panel) and PGPC (right panel). Data represent means ± SD (n = 6). p < 0.01 as compared to cells without PGL or PGPC, *represents p < 0.001 as compared to PMA + Iono-stimulated T-cells. NS = insignificant differences. p values were obtained by one-way ANOVA, followed by Fisher’s LSD testBack to article page
