Intestinal macrophages secrete TNF to induce local epithelial NF-κB activation. (A) Gating strategy for intestinal MP subsets in the cecal mucosa of mice depicted in B and C. (B and C) Flow cytometry analysis of cecal MPs from PBS- or LPS-injected (B) KappaBle mice for assessment of NF-κB activation (gating as shown in A; n = 3–5) or (C) WT mice for identification of TNF-producing MP subsets (gating as shown in A; n = 3–6). (D) Updated gating strategy for differentiation of intestinal DCs and macrophages as shown in . Lineage = NK1.1, CD3, B220. (E) For scRNAseq, CD45 + live MHCII + lineage (NK1.1, CD3, B220) − cells were sorted from the cecal mucosa of 40 min LPS-injected mice or PBS-treated controls ( n = 4 mice) and subsequently analyzed by scRNAseq (10X Genomics). T-distributed stochastic neighbor embedding plots showing the distribution of the analyzed cells indicated by cluster (left) or treatment (right). (F) Expression levels of intestinal MP markers: this analysis revealed two clear macrophages clusters (7 and 10). CD11b − CD103 + Xcr1 + DCs were represented in clusters 1–4, out of which cluster 2 mainly consisted of cells from LPS-treated mice, indicating that this might represent an activated state. This is in line with the secondary TNF production of this subset at later time points after injection, as detected by flow cytometry (C). Clusters 0 and 5 were positive for Sirpa and contained CD11b + CD103 + DCs (cluster 0) and CD11b + CD103 − DCs (cluster 5). While clusters 12 and 13 were positive for a number of monocyte/macrophage markers and therefore likely represent maturing macrophages, the assignment of clusters 6, 8, and 9 was challenging due to overlapping marker expression. These clusters, together with cluster 11 (mast cells), likely contained precursors (macrophage/DC, cluster 8) or contaminating cells (T cells, cluster 6 and 8; plasma cells, cluster 9). (G) Expression analysis of TLR4 signaling–associated genes. (H) Gene set enrichment analysis for macrophage clusters (7 and 10). (I) Frequency of DCs and macrophages in the cecum, small intestine, and colon of naive WT mice ( n = 5). Each circle represents one mouse (B, C, and I) or one cell (E). Black line: median. Combined data of two (I), three (B), or nine (C) independent experiments. Statistical analysis: one-way ANOVA with Tukey’s correction (C) or Mann–Whitney U test (B). *, P ≤ 0.05; **, P ≤ 0.01.

T-distributed stochastic neighbor embedding plots showing the distribution of the analyzed cells indicated by cluster (left) or treatment (right). (F) Expression levels of intestinal MP markers: this analysis revealed two clear macrophages clusters (7 and 10). CD11b − CD103 + Xcr1 + DCs were represented in clusters 1–4, out of which cluster 2 mainly consisted of cells from LPS-treated mice, indicating that this might represent an activated state. This is in line with the secondary TNF production of this subset at later time points after injection, as detected by flow cytometry (C). Clusters 0 and 5 were positive for Sirpa and contained CD11b + CD103 + DCs (cluster 0) and CD11b + CD103 − DCs (cluster 5). While clusters 12 and 13 were positive for a number of monocyte/macrophage markers and therefore likely represent maturing macrophages, the assignment of clusters 6, 8, and 9 was challenging due to overlapping marker expression. These clusters, together with cluster 11 (mast cells), likely contained precursors (macrophage/DC, cluster 8) or contaminating cells (T cells, cluster 6 and 8; plasma cells, cluster 9). (G) Expression analysis of TLR4 signaling–associated genes. (H) Gene set enrichment analysis for macrophage clusters (7 and 10). (I) Frequency of DCs and macrophages in the cecum, small intestine, and colon of naive WT mice ( n = 5). Each circle represents one mouse (B, C, and I) or one cell (E). Black line: median. Combined data of two (I), three (B), or nine (C) independent experiments. Statistical analysis: one-way ANOVA with Tukey’s correction (C) or Mann–Whitney U test (B). *, P ≤ 0.05; **, P ≤ 0.01.

TNF-mediated epithelial NF-κB activation occurs upon bacterial infection and induces an antibacterial response. (A) Representative two-photon microscopy images of cecal explants of streptomycin-pretreated p65 GFP-FL mice infected with S . Tm for 8–13.5 h ( n = 28). Categories for scoring of epithelial NF-κB activation status: “no activation” (green); “patchy activation” (blue); “full activation” (orange); “inflammation” (red; tissue distortion evident); “unspecified” (gray; was excluded from further analysis). Scale bars: 50 µm. (B) Distribution of the analyzed 28 samples of A among the four epithelial NF-κB activation categories (bottom). For simplification, the blue, orange, and red categories were summarized as “NF-κB signaling” (yellow, top). (C) Tnf transcript levels in the cecal mucosa of mice described in A and naive p65 GFP-FL mice, grouped according to the epithelial NF-κB activation status of the respective mice and depicted as 2 -ΔCT .

(E) Log 2 ratios of selected genes in a transcriptome analysis of TNF-treated (8 h, 5 ng/ml) compared with untreated small intestinal epithelial organoids . FDR, false discovery rate.

Tm in the cecal lumen (gated on O12 + cells, see ) were stained for surface C3 to assess coating of luminal bacteria by flow cytometry (C3 + population). MFI, median fluorescence intensity. Statistical analysis: Mann–Whitney U test (C, F, and G) or χ 2 test (D). *, P ≤ 0.05; **, P ≤ 0.01.
