Here we describe a step-by-step protocol inducing colonic inflammation in mice by adoptive transfer of CD4+CD45RB+ T cells into immunodeficient mice. We used C57BL/6 donor spleens and syngeneic Rag1-/- recipient mice, although other strains (e.g., BALB/c, 129S6/SvEv, non-obese diabetic (NOD)) and genetic models of immunodeficiency (e.g., SCID, Rag2-/-) may also be used4,14-16. It is well established that background strain affects e...

The inflammatory bowel diseases (IBD) Crohn&#8217;s disease and ulcerative colitis result from an incompletely defined and complex interaction between host immune responses, genetic susceptibility, environmental factors, and the enteric luminal contents1. Recent genome-wide association studies report associations between immune cell regulatory genes and IBD susceptibility2,3. Both innate and adaptive immune cell intrinsic genes are represented in these studies, indicating a central role for these cell populations in IBD pathogenesis.
There currently exist more than 50 animal models of human IBD. While no one model perfectly phenocopies human IBD, many are useful for studying various aspects of human disease, including disease onset and progression and the wound-healing response. In the method described here, intestinal inflammation is initiated with syngeneic splenic CD4+CD45RBhigh T cell adoptive transfer into T and B cell deficient recipient mice4. The CD4+CD45RBhigh T cell population contains mainly na&#239;ve T cells primed for activation that are capable of inducing chronic small bowel and colonic inflammation. This method allows the researcher to modify key experimental variables, including both innate and adaptive immune cell populations, to answer biologically relevant questions relating to disease pathogenesis. Additionally, this method provides precise initiation of disease onset and a well-characterized experimental time course. This permits the kinetic study of clinical features of disease progression in mice. Intestinal inflammation induced by this method shares many features with human IBD, including chronic large and small bowel transmural inflammation, pathogenesis driven by cytokines such as TNF and IL-12, and systemic symptoms such as wasting5. Thus, it is an ideal model system for studying the pathogenesis of human IBD.
The method here describes in detail the protocol for inducing experimental colitis by adoptive transfer of CD4+CD45RBhigh T cells into Rag1-/- mice. We discuss key technical steps, expected results, optimization, and trouble-shooting. We address the required elements for the successful development of this murine model of intestinal inflammation for research purposes.

induction of murine intestinal inflammation by adoptive transfer of effector cd4+cd45rbhigh t cells into immunodeficient mice

There are many different animal models available for studying the pathogenesis of human inflammatory bowel diseases (IBD), each with its own advantages and disadvantages. We describe here an experimental colitis model that is initiated by adoptive transfer of syngeneic splenic CD4+CD45RBhigh T cells into T and B cell deficient recipient mice. The CD4+CD45RBhigh T cell population that largely consists of na&#239;ve effector cells is capable of inducing chronic intestinal inflammation, closely resembling key aspects of human IBD. This method can be manipulated to study aspects of disease onset and progression. Additionally it can be used to study the function of innate, adaptive, and regulatory immune cell populations, and the role of environmental exposures, i.e., the microbiota, in intestinal inflammation. In this article we illustrate the methodology for inducing colitis with a step-by-step protocol. This includes a video demonstration of key technical aspects required to successfully develop this murine model of experimental colitis for research purposes.

Approximately 10 x 106 CD4+CD45RBhigh T cells from 10 spleens from adult C57BL/6 donor mice are reliably isolated. This number will vary depending on the age and strain of the donor mouse and the proficiency of the researcher. When 4 x 105 C57BL/6 CD4+CD45RBhigh T cells are transferred into C57BL/6 Rag1-/- recipient mice, clinical signs of disease emerge around week 5 post-repletion or sooner if mice are genetically susceptible to more ...
