Intestinal bacteria induce TSLP to promote mutualistic T-cell responses

Nicola Harris, Mario Michael Zaiss, Ilaria Mosconi

Thymic stromal lymphopoietin (TSLP) is constitutively expressed in the intestine and is known to regulate inflammation in models of colitis. We show that steady-state TSLP expression requires intestinal bacteria and has an important role in limiting the ex ...

Investigating the acoustic release of doxorubicin from targeted micelles

Jeffrey Alan Hubbell

The main problem associated with the administration of anti-cancer medication is that the drug is delivered throughout the body causing undesirable side effects. Therefore, it is important to synthesize drug carriers capable of minimizing the adverse side ...

Low dose endoluminal photodynamic therapy improves murine T cell-mediated colitis

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht, François André Borle, Dominique Velin

Background and study aims: Low dose photodynamic therapy (LDPDT) may modify the mucosal immune response and may thus provide a therapy for Crohn's disease. We evaluated the efficacy and safety of this technique in a murine T cell-mediated colitis model. ...

Compositions and use of sulfasalazine

Kai Johnsson, Christopher Chidley

The invention relates to compositions comprising sulfasalazine or sulfapyridine and products of a biosynthetic pathway that requires tetrahydrobiopterin. Such compositions are useful for the treatment of inflammatory bowel diseases or rheumatoid arthritis, ...

Bcl9/Bcl9l are critical for Wnt-mediated regulation of stem cell traits in colon epithelium and adenocarcinomas

Michel Aguet, Mauro Delorenzi, Pascale Anderle Pedone, Norbert Wiedemann, Sylvie André Baflast

Canonical Wnt signaling plays a critical role in stem cell maintenance in epithelial homeostasis and carcinogenesis. Here, we show that in the mouse this role is critically mediated by Bcl9/Bcl9l, the mammalian homologues of Legless, which in Drosophila is ...

LRH-1-mediated glucocorticoid synthesis in enterocytes protects against inflammatory bowel disease

Johan Auwerx, Kristina Schoonjans

Liver receptor homolog-1 (LRH-1) is a nuclear receptor involved in intestinal lipid homeostasis and cell proliferation. Here we show that haploinsufficiency of LRH-1 predisposes mice to the development of intestinal inflammation. Besides the increased infl ...

In vivo imaging of farnesoid X receptor activity reveals the ileum as the primary bile acid signaling tissue

Johan Auwerx

We generated and characterized a firefly luciferase reporter mouse for the nuclear receptor farnesoid X receptor (FXR). This FXR reporter mouse has basal luciferase expression in the terminal ileum, an organ with well-characterized FXRalpha signaling. In v ...

Daily dosing of rifapentine cures tuberculosis in three months or less in the murine model

Ming Zhang

Availability of an ultra-short-course drug regimen capable of curing patients with tuberculosis in 2 to 3 mo would significantly improve global control efforts. Because immediate prospects for novel treatment-shortening drugs remain uncertain, we examined ...

Photodynamic therapy as a novel therapeutic approach for the treatment of Crohn's disease

Hubert van den Bergh, Georges Wagnières, Dominique Velin

Photodynamic therapy (PDT) may modify the mucosal immune response and thus serve as a therapy for Crohn’s disease (CD). After evaluating safety in BALB/c mice and establishing an endoscopic index of colitis (EIC), we could demonstrate that a single «low do ...

Intestinal antiinflammatory effect of 5-aminosalicylic acid is dependent on peroxisome proliferator-activated receptor-gamma

Johan Auwerx, Walter Wahli

5-aminosalicylic acid (5-ASA) is an antiinflammatory drug widely used in the treatment of inflammatory bowel diseases. It is known to inhibit the production of cytokines and inflammatory mediators, but the mechanism underlying the intestinal effects of 5-A ...
