Abstract
OBJECTIVE Perianal Crohn's disease (pCD) occurs in up to 40% of patients with CD and is associated with poor quality of life, limited treatment responses and poorly understood aetiology. We performed a genetic association study comparing CD subjects with and without perianal disease and subsequently performed functional follow-up studies for a pCD associated SNP in Complement Factor B (CFB). DESIGN Immunochip-based meta-analysis on 4056 pCD and 11 088 patients with CD from three independent cohorts was performed. Serological and clinical variables were analysed by regression analyses. Risk allele of rs4151651 was introduced into human CFB plasmid by site-directed mutagenesis. Binding of recombinant G252 or S252 CFB to C3b and its cleavage was determined in cell-free assays. Macrophage phagocytosis in presence of recombinant CFB or serum from CFB risk, or protective CD or healthy subjects was assessed by flow cytometry. RESULTS Perianal complications were associated with colonic involvement, OmpC and ASCA serology, and serology quartile sum score. We identified a genetic association for pCD (rs4151651), a non-synonymous SNP (G252S) in CFB, in all three cohorts. Recombinant S252 CFB had reduced binding to C3b, its cleavage was impaired, and complement-driven phagocytosis and cytokine secretion were reduced compared with G252 CFB. Serine 252 generates a de novo glycosylation site in CFB. Serum from homozygous risk patients displayed significantly decreased macrophage phagocytosis compared with non-risk serum. CONCLUSION pCD-associated rs4151651 in CFB is a loss-of-function mutation that impairs its cleavage, activation of alternative complement pathway, and pathogen phagocytosis thus implicating the alternative complement pathway and CFB in pCD aetiology.

Abstract
BACKGROUND & AIMS Tumor necrosis factor (TNF) superfamily member tumor necrosis factor-like protein 1A (TL1A) has been associated with the susceptibility and severity of inflammatory bowel diseases. However, the function of the tumor necrosis factor-like protein 1A and its receptor death receptor 3 (DR3) in the development of intestinal inflammation is incompletely understood. We investigated the role of DR3 expressed by intestinal epithelial cells (IECs) during intestinal homeostasis, tissue injury, and regeneration. METHODS Clinical phenotype and histologic inflammation were assessed in C57BL/6 (wild-type), Tl1a-/- and Dr3-/- mice in dextran sulfate sodium (DSS)-induced colitis. We generated mice with an IEC-specific deletion of DR3 (Dr3ΔIEC) and assessed intestinal inflammation and epithelial barrier repair. In vivo intestinal permeability was assessed by fluorescein isothiocyanate dextran uptake. Proliferation of IECs was analyzed by bromodeoxyuridine incorporation. Expression of DR3 messenger RNA was assessed by fluorescent in situ hybridization. Small intestinal organoids were used to determine ex vivo regenerative potential. RESULTS Dr3-/- mice developed more severe colonic inflammation than wild-type mice in DSS-induced colitis with significantly impaired IEC regeneration. Homeostatic proliferation of IECs was increased in Dr3-/- mice, but blunted during regeneration. Cellular localization and expression of the tight junction proteins Claudin-1 and zonula occludens-1 were altered, leading to increased homeostatic intestinal permeability. Dr3ΔIEC mice recapitulated the phenotype observed in Dr3-/- mice with increased intestinal permeability and IEC proliferation under homeostatic conditions and impaired tissue repair and increased bacterial translocation during DSS-induced colitis. Impaired regenerative potential and altered zonula occludens-1 localization also were observed in Dr3ΔIEC enteroids. CONCLUSIONS Our findings establish a novel function of DR3 in IEC homeostasis and postinjury regeneration independent of its established role in innate lymphoid cells and T-helper cells.

Abstract
The intestinal immune system and microbiota are emerging as important contributors to the development of metabolic syndrome, but the role of intestinal dendritic cells (DCs) in this context is incompletely understood. BATF3 is a transcription factor essential in the development of mucosal conventional DCs type 1 (cDC1). We show that Batf3-/- mice developed metabolic syndrome and have altered localization of tight junction proteins in intestinal epithelial cells leading to increased intestinal permeability. Treatment with the glycolysis inhibitor 2-deoxy-D-glucose reduced intestinal inflammation and restored barrier function in obese Batf3-/- mice. High-fat diet further enhanced the metabolic phenotype and susceptibility to dextran sulfate sodium colitis in Batf3-/- mice. Antibiotic treatment of Batf3-/- mice prevented metabolic syndrome and impaired intestinal barrier function. Batf3-/- mice have altered IgA-coating of fecal bacteria and displayed microbial dysbiosis marked by decreased obesity protective Akkermansia muciniphila, and Bifidobacterium. Thus, BATF3 protects against metabolic syndrome and preserves intestinal epithelial barrier by maintaining beneficial microbiota.

Abstract
Dectin-1 recognizes β-glucan in fungal cell walls, and activation of Dectin-1 in dendritic cells (DCs) influences immune responses against fungi. Although many studies have shown that DCs activated via Dectin-1 induce different subsets of T helper cells according to different cytokine milieus, the mechanisms underlying such differences remain unknown. By harnessing polymorphic Candida albicans and polystyrene beads of different sizes, we find that target size influences production of cytokines that control differentiation of T helper cell subsets. Hyphal C. albicans and large beads activate DCs but cannot be phagocytosed due to their sizes, which prolongs the duration of Dectin-1 signaling. Transcriptomic analysis reveals that expression of Il33 is significantly increased by larger targets, and increased IL-33 expression promotes TH9 responses. Expression of IL-33 is regulated by the Dectin-1-SYK-PLCγ-CARD9-ERK pathway. Altogether, our study demonstrates that size of fungi can be a determining factor in how DCs induce context-appropriate adaptive immune responses. Oh et al. show that dendritic cells exposed to C. albicans hyphae more strongly induce IL-9-producing T cells compared with cells exposed to yeast. They find that this TH9 response is driven in large part by Dectin-1 sensing microbe size, leading to elevated production of IL-33.

Abstract
Abstract
The maintenance of intestinal homeostasis depends on a complex interaction between microbiota, intestinal epithelial barrier, and the immune system. Alteration in of one of these components could lead to the development of inflammatory bowel diseases (IBD). Norovirus infection of mice with a mutation in the Crohn’s disease susceptibility gene Atg16L1 induces intestinal inflammation. Moreover, persistent norovirus infection leads to intestinal virus-specific CD8+ T cells responses. However, the role of the enteric virome in IBD is still poorly understood. Toll-like receptor 7 (TLR7) recognizes single-stranded RNA viruses. Here, we investigate the role of TLR7 in intestinal homeostasis and inflammation. At steady state, Tlr7−/− mice have an approx. 10-fold increase in small and large intestinal lamina propria (LP) granzyme B+ tissue-resident memory (Trm) CD8+ T cells compared to WT mice (WT: 5.5, Tlr7−/−: 59.5 %, p < 0.005), reminiscent of persistent norovirus infection. Furthermore, Tlr7−/− mice were more susceptible to dextran sulfate sodium (DSS) colitis with more severe inflammation (Histoscore: WT: 7.6, Tlr7−/−: 12.7, p < 0.005), increased disease activity index (WT: 5.5, Tlr7−/−: 7.4, p < 0.05), and increased secretion of IFNg (WT: 5.2, Tlr7−/−: 24.2 ng/ml, p < 0.005) and TNFα (WT: 108.6, Tlr7−/−: 191.8 pg/ml, p < 0.05). Increased colonic inflammation was associated with increased LP Trm CD8+ T cells (WT: 3.9, Tlr7−/−: 42.0 %, p < 0.005). Our data shows that TLR7-deficiency promotes the development of LP Trm CD8+ T cells and increases susceptibility to DSS colitis. In conclusion, TLR7 plays an important role in maintaining immune response to intestinal viruses and protects against development of colitis.

Abstract
T helper 9 (TH9) cells are important for the development of inflammatory and allergic diseases. The TH9 transcriptional network converges signals from cytokines and antigen presentation but is incompletely understood. Here, we identified TL1A, a member of the TNF superfamily, as a strong inducer of mouse and human TH9 differentiation. Mechanistically, TL1A induced the expression of the transcription factors BATF and BATF3 and facilitated their binding to the Il9 promoter leading to enhanced secretion of IL-9. BATF- and BATF3-deficiencies impaired IL-9 secretion under TH9 and TH9-TL1A-polarizing conditions. In vivo, using a T-cell transfer model, we demonstrated that TL1A promoted IL-9-dependent, TH9 cell-induced intestinal and lung inflammation. Neutralizing IL-9 antibodies attenuated TL1A-driven mucosal inflammation. Batf3-/- TH9-TL1A cells induced reduced inflammation and cytokine expression in vivo compared to WT cells. Our results demonstrate that TL1A promotes TH9 cell differentiation and function and define a role for BATF3 in T-cell-driven mucosal inflammation.

Abstract
Abstract
The maintenance of intestinal homeostasis depends on a complex interaction between microbiota, intestinal epithelial barrier and immune system. Alteration in of one of these components could lead to the development of chronic inflammatory diseases such as inflammatory bowel diseases (IBD). Recent studies have associated obesity with more severe IBD. In obesity, pro-inflammatory macrophages accumulate in adipose tissue and their numbers correlate with inflammation and insulin resistance. BATF3 is a transcription factor implicated in the development of conventional dendritic cells type 1 (cDC1). Here, we show that aged Batf3−/− mice developed obesity as characterized by increased body weight, fasting glucose levels (Batf3−/−: 213, WT: 115 mg/dl, p < 0.005), size of abdominal white adipocyte, and development of hepatosteatosis. We also observed increased intestinal permeability in Batf3−/− mice (FITC-dextran gavage; p < 0.01) suggesting impaired epithelial barrier function. Feeding high-fat diet for 2 months further enhanced the metabolic phenotype in Batf3−/− mice, leading to increased fasting glucose levels (300 vs. 246 mg/dl, p < 0.05), and increased adipocyte size. Moreover, during high-fat diet Batf3−/− mice were more susceptible to dextran sulfate sodium (DSS) colitis with more severe cecal inflammation, increased gut and mesenteric fat M1 macrophages (p < 0.05). Our data suggest that deficiency of the transcription factor BATF3 and lack of cDC1 alters the intestinal epithelial barrier, promotes the development of obesity, and increases susceptibility to DSS. In conclusion, BATF3-dependent cDC1 play an important role in maintaining the intestinal epithelial barrier and are protective for the development of obesity.

Abstract
OBJECTIVE Epidemiological and clinical data indicate that patients suffering from IBD with long-standing colitis display a higher risk to develop colorectal high-grade dysplasia. Whereas carcinoma invasion and metastasis rely on basement membrane (BM) disruption, experimental evidence is lacking regarding the potential contribution of epithelial cell/BM anchorage on inflammation onset and subsequent neoplastic transformation of inflammatory lesions. Herein, we analyse the role of the α6β4 integrin receptor found in hemidesmosomes that attach intestinal epithelial cells (IECs) to the laminin-containing BM. DESIGN We developed new mouse models inducing IEC-specific ablation of α6 integrin either during development (α6ΔIEC) or in adults (α6ΔIEC-TAM). RESULTS Strikingly, all α6ΔIEC mutant mice spontaneously developed long-standing colitis, which degenerated overtime into infiltrating adenocarcinoma. The sequence of events leading to disease onset entails hemidesmosome disruption, BM detachment, IL-18 overproduction by IECs, hyperplasia and enhanced intestinal permeability. Likewise, IEC-specific ablation of α6 integrin induced in adult mice (α6ΔIEC-TAM) resulted in fully penetrant colitis and tumour progression. Whereas broad-spectrum antibiotic treatment lowered tissue pathology and IL-1β secretion from infiltrating myeloid cells, it failed to reduce Th1 and Th17 response. Interestingly, while the initial intestinal inflammation occurred independently of the adaptive immune system, tumourigenesis required B and T lymphocyte activation. CONCLUSIONS We provide for the first time evidence that loss of IECs/BM interactions triggered by hemidesmosome disruption initiates the development of inflammatory lesions that progress into high-grade dysplasia and carcinoma. Colorectal neoplasia in our mouse models resemble that seen in patients with IBD, making them highly attractive for discovering more efficient therapies.

Abstract
Despite recommendations to provide isoniazid preventive therapy (IPT) to eligible children aged <5 years who are in close contact with an infectious tuberculosis (TB) case, IPT delivery in high-burden settings remains poor. To evaluate the current system supporting IPT delivery to children in an urban community, South Africa, we reviewed the recording practices of a local clinic regarding management of children exposed to a current adult TB case. No standardised IPT management tools existed. Only 21% of children eligible for IPT had documentation of IPT delivery. There is a need to implement systems that support IPT recommendations in high-burden settings.
