Abstract or Project Description

Inflammatory Bowel Disease (IBD) comprises incurable chronic diseases of the gut which oscillate between periods of disease worsening (i.e. relapse) and relatively normal health (i.e. remission). Whilst current medicines often reduce this see-sawing problem, their effectiveness eventually wanes to the point where a large percentage of IBD patients still need hospitalisation and major surgery during their lifetime. Indeed, our current inability to cure IBD denotes that existing medicines do not tackle the root cause of IBD.

In this context, we have discovered that gut cells in IBD patients are much more prone to dying than gut cells in healthy patients. Remarkably, this shift towards exaggerated gut cell death also occurs in IBD patients who are in remission and experiencing a period of “normal health,” leading us to predict that excessive gut cell death is a root cause of IBD. In this project, we will aim to understand why gut cells in IBD patients are primed to die, and test whether correcting this molecular defect can achieve long-lasting remission.

Abstract or Project Description

Our gut is constantly exposed to environmental harms, such as bacteria and dietary products, among others. The epithelium layer of our intestinal tract, which is the most exposed to the external world, contains a variety of immune cells, which likely play an important role in patrolling and defending our intestine. However, how these cells protect epithelial cells and the host from pathogens and other insults is still poorly understood. We aim to better understand how a specific subset of intraepithelial immune cells, known as gd T cells, contributes to gut homeostasis. We found that these cells are highly decreased in Crohn’s disease (CD) patients, suggesting that they exert protective roles during disease. In addition, we found that they are heterogeneous and can crosstalk with either epithelial cells or other immune cells located deeper in the tissue. Herein, we plan to design functional experiments to better understand their role in the context of gut immune responses and how they affect surrounding epithelial or other immune cell types. In addition, we aim to identify if they derive from a common precursor or if they are highly diverse and whether this scenario is altered in CD.

Microbiota small molecules correlate with IBD pathogenesis, yet the molecular mechanisms behind remain elusive. We recently developed gene manipulation tools in multiple gut Clostridia commensals, and by mutating the responsible gene and mono-colonizing germ-free mice with the mutant, we can switch specific microbiota metabolites on/off in vivo and found that metabolites derived from Clostridia amino acid transamination, like branched short-chain fatty acids (BSCFAs) suppress intestine IgA plasma cells. Many microbiota-associated metabolites, including BSCFAs, are derived via microbial transamination of dietary amino acids and are highly abundant in the host. Multiple studies have shown that this group of microbial metabolites is significantly different between IBD patients and healthy humans. We hypothesize that microbiota metabolites from amino acid transamination mediate intestine immunity and inflammation. Herein we will apply Clostridium CRISPR-based toolsets to modulate these amino acid-derived metabolites in vitro and in vivo, investigate their effects on intestinal immunity and inflammation in germ-free and colitis mouse models, and look into clinical samples to determine if their levels are positively correlated with disease severity in IBD patients. Our findings will uncover previously unknown molecular mechanisms behind microbiome-IBD correlation and facilitate the identification of new therapeutic targets and new biomarkers for IBD prevention and treatment.

The Association of Black Gastroenterologists and Hepatologists (ABGH) proposes a new mentorship program, “ABGH Rising,” a national mentorship and education program to promote health equity and address the root causes of health inequities, including IBD.

Abstract or Project Description

Created in response to the California wildfires of 2020, “BURNING WILD” is a devised performance incorporating physical theatre, song, dance, documentary video and puppetry to tell a collaged docu-myth. Born out of a call for growth and transformation, “BURNING WILD” re-envisions the intersection of ensemble theater and radical community care, using arts and wellness as cultural liberation practice.

Abstract or Project Description

Azora Therapeutics is developing a novel small molecule, AT177, for the treatment of refractory ulcerative colitis (UC). UC is a chronic inflammatory disease of the colon that affects over 1 million individuals in the United States and is associated with poor quality of life. Efficacy of currently available therapy is suboptimal, and most patients cannot sustain long-term remission, with 14% ultimately requiring colectomy surgery. AT177 is a potential first-in-class oral small molecule aryl hydrocarbon receptor (AhR) agonist. AhR has been shown to play an important in regulating healthy immune and barrier function in the colon. The aim of this project is to conduct preclinical studies to support advancement to clinical studies in humans.
