Abstract or Project Description

Males and females with Inflammatory Bowel Disease (IBD) differ in terms of incidence of disease, symptoms and response to treatments. The underlying reasons are largely unknown. Understanding why these sex differences exist could reveal why many patients develop IBD as they enter young adulthood. Sex hormones such as testosterone surge during adolescence and then circulate at very different levels in males and females. These hormones are powerful signaling molecules that regulate diverse aspects of physiology and may play a role in IBD. Clinical studies hint that testosterone signaling is protective in IBD, but it is largely unclear which cells this hormone signals to in the gut and how this signaling might influence intestinal inflammation. We have discovered that testosterone signals to an important population of nerve cells along the gut-brain axis, called nociceptors, that communicate information about the gut to the brain and regulate local immune responses. Using mice in which we can specifically disable testosterone signaling in nociceptors without altering it in the rest of the body, we will determine how testosterone influences inflammation and tissue repair in colitis. The results will advance the understanding of how sex hormones impact disease activity in IBD, potentially explain sex-dependent outcomes and inform therapeutic strategies.

Inappropriate and chronic inflammatory responses underly the development of Inflammatory Bowel Diseases (IBD), including both ulcerative colitis and Crohn’s disease. This process is an intertwined, inter-cellular cascade among diverse immune cells and tissue stroma. The interactions between immune and stromal cells not only propagate inflammatory responses but also regulate resolution of inflammation. Yet, we do not understand how immune cells interact with tissue stroma when intestinal inflammation occurs and resolve. We propose to first develop cutting-edge technologies that discover interacting partners of immune cells in vivo in a high-throughput and unbiased manner. We will then apply these new tools to identify the interactomes of immune cells over the course of intestinal inflammation. Funding from the Kenneth Rainin Foundation will support our program to map out the path of immune-stromal interactions from a healthy intestine to an inflamed tissue to recovery and repair. Targeting immune-stromal interactions that cause inflammatory propagation as well as the resolution will establish a new strategy to alleviate inflammation. Our long-term goal is to leverage this knowledge to switch “inflammatory interactions” to “resolving interactions” in order to restore intestinal homeostasis, which will ultimately curtail IBD and its devastating health implications.

Abstract or Project Description

The epithelial cells lining the intestine control responses to gut bacteria, limiting intestinal damage in Crohn’s disease. A critical gene in this pathway is DUOX2, which is up-regulated in response to bacteria, and helps maintain intestinal health. We discovered that Crohn’s disease patients who carry genetic variants in DUOX2 are more likely to progress to fibrotic disease complications requiring surgery. We tested an intestinal gene signature for refractory pediatric Crohn’s disease in a database containing 2000 small molecules, identifying 140 which might be more effective therapies. Our studies will now utilize a novel Human Intestinal Organoid, or “mini-gut” model system for refractory pediatric Crohn’s disease that we have developed informed by genetic factors like DUOX2. We have prepared stem cells from pediatric Crohn’s disease patients who did or did not have DUOX2 genetic variants, and will differentiate them into white blood cells and human intestinal organoids. This novel model system will be used to test ways to modulate pathways linked to fibrosis in patients, by screening the top small molecules which we have identified as potentially beneficial. Our studies will advance precision medicine, by developing a platform to screen new therapies in patient-derived intestinal organoids with clinically important genetic variants.

Abstract or Project Description

Our gut microbiome has a strong influence on a variety of diseases, including Inflammatory Bowel Disease (IBD). Fungi form an integral part the human gut microbiome, and studies in mice showed that fungi may have a substantial influence on inflammation and IBD development, while antibody responses against fungi constitute important clinical IBD diagnostic tools. However, the functional roles of fungi in modulating IBD, and whether they can be harnessed towards new treatments, remain elusive to date. In this study, we plan to uncover the role of fungi in IBD by taking biopsy samples of the gastrointestinal tract from IBD patients. From the biopsies, we plan to grow mini-guts, called organoids, in petri dishes. We have previously shown that it is possible to use these organoids cultured with microbes to study the interactions between bacteria and the gut cells. Thus, using IBD-patient derived gut organoids and specific IBD-relevant fungi, we will be able to identify mechanisms of the interactions between the diseased gut cells and the fungi. Interesting fungal candidates will be further validated in IBD-like mouse models. This combination of different approaches will allow us to better understand the influence of fungi on IBD progression and develop new intervention strategies for treating IBD.

Abstract or Project Description

Monogenic forms of Inflammatory Bowel Disease (IBD) offer valuable insights into key regulators of intestinal inflammation. Building on our previous advancements in characterizing very early onset IBD (VEO-IBD) patients with monogenic CASP8 and RIPK1 deficiencies, we aim to elucidate the key factors and molecular mechanisms of disrupted cell death responses (necroptosis) in these life-threatening conditions.

Our hypothesis proposes that unbiased and simultaneous exploration of thousands of genes by employing discovery-oriented pooled CRISPR screens will illuminate the signaling network governing perturbed inflammatory and cell death responses, shedding light on novel therapeutic targets for RIPK1 and CASP8 deficiencies. In the proposed CRISPR screen, we will assess the enrichment of guide RNAs from genome-wide libraries that are capable of rescuing uncontrolled LPS-induced necroptosis and inflammatory responses in RIPK1- and CASP8-deficient macrophages using next-generation sequencing and bioinformatics analysis. A set of prioritized targets will be characterized in advanced genetically engineered induced pluripotent stem cell-derived human disease models.

Given the potency of monogenic IBD as a powerful model for defining key regulators of intestinal homeostasis, we anticipate uncovering critical insights into the molecular pathomechanisms and druggable targets of inflammation, contributing valuable knowledge for rare and common forms of IBD according to the translational genomics principle bedside-to-bench and back.

Abstract or Project Description

The intestine exerts the vital function of maximizing nutrient uptake from the diet we ingest, being constantly exposed to external stimulation by food components. Alterations in the timing of food intake and diet composition have been associated with the development of immune-related intestinal dysfunctions, including IBS. However, despite its profound biological and clinical relevance, there is a major gap in our understanding of how intestinal immune health is affected by diet. Recently, we uncovered that gut neurons are activated by the diet, and they can control intestinal immune responses. The long-term goal of this proposal is to determine how the diet is sensed by these neurons that have immune regulatory properties. Our studies are expected to uncover dietary and neuronal therapeutic targets to gut disturbances associated with a dysregulation in local immune responses, including IBS.
