IL6 and delirium: Moreover, similar to the effects of IL6 antibody during the proliferation phase on the production of IL12, treatment of cells with serum samples from delirium patients and IL6 antibody during the differentiation stage prevented the production of IL13 in cell supernatant, (Time point 1, delirium vs delirium + IL6 antibody; IL13: 24.6 ± 3 pg/ml vs 5.1 ± 2.7 pg/ml, p < 0.0001,), again with no differences between Time point 1 and Time point 2 (Figs. 1e, 5g, h).
