Dr. Jonathan Jacobs is an Assistant Professor-in-Residence in the Division of Digestive Diseases within the UCLA Department of Medicine. His research background is in immunology and the intestinal microbiome. He originally trained under Diane Mathis and Christophe Benoist at Harvard, where he published three first author papers on the immunopathological mechanisms of arthritis in an autoantibody-mediated model. He later joined Jonathan Braun’s lab at UCLA to investigate the interactions of the mucosal immune system and the intestinal microbiome in inflammatory bowel disease (IBD). He utilized human cohorts and transgenic mice to demonstrate that the IBD-associated genes RORC and TL1A, both involved in mucosal immunity, garden the intestinal microbiome. This raises the possibility that genetic risk factors promote IBD through their effects on the microbiome. An ongoing human cohort study with Dr. Braun aims to define the microbial and metabolomics features of IBD in the colonic mucosa and to characterize their relationship to IBD-associated genetic polymorphisms. In a separate translational study, he found that healthy relatives of pediatric IBD patients could be classified by their intestinal microbial and metabolomics profiles into “enterotypes” and “metabotypes” that may predict their future risk for IBD. He has authored a review article, a commentary, and two textbook chapters on intestinal host-microbiome interactions. His current research employs in vivo models and multi’omics analysis of IBD cohorts to define the role of IBD-associated genes in shaping the intestinal microbiome and to identify microbial products that promote IBD.
