CD14 and ALPK1 Affect Expression of Tight Junction Components and Proinflammatory Mediators upon Bacterial Stimulation in a Colonic 3D Organoid Model

Figure 6

Expression of proinflammatory mediators after E. coli Nissle stimulation. Changes in gene expression of cytokines and their supernatant concentration after 6 hours of E. coli Nissle 1917 (EcN) stimulation were compared between wild-type (WT) and knockout organoids. Values were normalized to unstimulated controls within each genotype for each experiment and represent the means with 95% CI. Unstimulated: WT , Cd14^-/-, Il10^-/-, and Alpk1^-/-. Stimulated: WT , Il10^-/-, Cd14^-/-, and Alpk1^-/-. (a) Tnfα/TNFα, (b) Cxcl1/CXCL1, (c) Cxcl2/CXCL2, and (d) Cxcl5/CXCL5. Stimulated versus unstimulated values were compared using unpaired -tests. Welch’s correction was used in case of unequal variances. One-way analysis of variance followed by Dunnett’s multiple comparisons was performed. Each knockout genotype was compared to WT. , , , and .
