- AB In this study, we describe a novel murine model of chronic intestinal
- inflammation induced by the hapten reagent 2,4,6-trinitrobenzene
- sulfonic acid (TNBS). Rectal application of low doses of TNBS in BALB/c
- and SJL/J mice resulted in a chronic transmural colitis with severe
- diarrhea, weight loss, and rectal prolapse, an illness that mimics some
- characteristics of Crohn's disease in humans. The colon of TNBS-treated
- mice on day 7 was marked by infiltration of CD4+ T cells; furthermore,
- in situ polymerase chain reaction studies revealed high levels of
- interferon (IFN)-gamma mRNA in diseased colons. Isolated lamina propria
- (LP) CD4+ T cells from TNBS-treated mice stimulated with anti-CD3 and
- anti-CD28 antibodies exhibited a Th1 pattern of cytokine secretion: a
- 20-50-fold increase in IL-2 and IFN-gamma levels and a 5-fold decrease
- in IL-4 levels as compared with those of stimulated LP CD4+ T cells from
- control BALB/c mice. Administration of monoclonal anti-IL-12 antibodies
- to the TNBS-treated mice both early (at 5 d) and late (at 20 d) after
- induction of colitis led to a striking improvement in both the clinical
- and histopathological aspects of the disease and frequently abrogated
- the established colitis completely. Furthermore, LP CD4+ T cells
- isolated from anti-IL-12-treated mice failed to secrete IFN-gamma upon
- in vitro stimulation. In summary, the data demonstrate the pivotal role
- of IL-12 and IFN-gamma in a TNBS-induced murine model of chronic
- intestinal inflammation. Furthermore, they suggest the potential utility
- of anti-IL-12 antibodies in patients with Crohn's disease.
