Cytokine secretion of bone-marrow-derived macrophages (BMDM) in response to co-incubation with dying cells. BMDM were co-cultivated for 18 h with cells dying by the indicated stimuli. The respective supernatants were analyzed for the cytokines IL-1α, IL-1β, IFNβ, IL-10, IL-27, IL-6 and IL-12 (N=8). Shown are means with their standard error of the mean. A one-way ANOVA analysis with Bonferroni correction for multiple comparisons was performed. *, ** and *** indicate statistical significance with P-values of 0.05, 0.01 and 0.001, respectively; ns, not significant
