Interleukin 6 (IL-6) protein release under pressure and MTX treatment. A IL-6 protein release did not significantly differ under pressure (n ≥ 12, ns, unpaired t-test) B IL-6 protein release was not influenced by MTX treatment (1 µg/ml) (n ≥ 12, ns, one-way ANOVA), but was slightly increased under concurrent pressure application (n ≥ 12, ** p < 0.001, one-way ANOVA). The values are presented as the mean ± SEM
