Effect of a rFgLGMN-1 and b rFgLGMN-2 on the proliferation of peripheral blood mononuclear cells (PBMCs). PBMCs treated with concanavalin A (ConA) and phosphate-buffered saline (PBS) were used as a control, and were also treated with different concentrations of rFgLGMN-1 and rFgLGMN-2 for 48 h. rFgLGMN-1 and rFgLGMN-2 inhibited the proliferation of PBMCs. Graphs represent means ± SDs of results from three independent biological replicates. Asterisks indicate statistically significant differences between treated cells and control cells: *P < 0.05, **P < 0.01, ****P < 0.0001, ns non-significant. For other abbreviations, see Figs. 1 and 2
