Beta-glucans induced training and increase resilience in both trained immunity protocols. The protocols of the in vitro training and resilience model for (A–D) are schematically depicted in Figure 1 and described in the legend to Figure 1 , with the adjustment that 50 ng/ml M-CSF was added to step I-III for (C) and (D) Results from training (A) and induced resilience (B) when applying the established protocol and training (C) and induced resilience (D) when applying the controlled M-CSF-mediated macrophage differentiation protocol are shown in a bar graph as average pg/ml TNF-α ± SD of n = 5 different donors. Data was analyzed with paired Student’s t test and statistical significances were indicated: *P < 0.05 compared to the medium control; **P < 0.01 compared to the medium control; #P < 0.05 compared to the LPS control.
