Overview

Kara Gross Margolis, MD is an Associate Professor of Pediatrics and a pediatric gastroenterologist with a clinical expertise in brain-gut axis disorders, and particularly autism spectrum disorders (ASD). She has published highly novel observations on the roles that enteric neurotransmitters, specifically serotonin and oxytocin, play in enteric nervous system (ENS) development and how, when signaling of either of these neurotransmitters is abnormal, result in intestinal inflammation and/or motility dysfunction. She has more recently leveraged her expertise to study disorders of the brain-gut axis from the perspective of the ENS. Her studies in this area thus far have focused on two disorders that have been classically thought of as central nervous system (CNS)-centric, ASD and developmental antidepressant (selective serotonin reuptake inhibitor; SSRI) exposure. Her overall goals are to pursue translational research that interrogates basic mechanisms underlying important clinical conditions, in order to utilize this knowledge to develop novel therapeutic strategies.

Research

The goal of Dr. Margolis’ research is to understand the enteric nervous system (ENS) and disorders that have in common an effect both on the brain and the gut, sometimes referred to as the “brain-gut axis”. She has published novel observations on the roles that enteric neurotransmitters (specifically serotonin and oxytocin) play in ENS development and how signaling from such neurotransmitters may, when abnormal, result in gastrointestinal (GI) disorders such as inflammatory bowel disease (e.g., Crohn’s disease and ulcerative colitis), motility dysfunction (e.g., chronic constipation or irritable bowel syndrome) and necrotizing enterocolitis (a devastating intestinal inflammatory disorder primarily of preterm infants). This research has recently provided important insights into how abnormalities of the ENS can arise in children with brain-gut axis disorders such as autism, antenatal antidepressant exposure and irritable bowel syndrome.
