Welcome to the Mangalam Lab

We believe that restoring balance between the microbiota and the immune system has the power to transform human health. Our work begins with a simple question: what happens when this partnership breaks down, and how can we rebuild it?

Guided by a bedside-to-bench-to-bedside approach, we combine human cohort studies with mechanistic work in immune cells, organoids, and animal models to uncover how microbial communities and their metabolites shape neuroinflammation, tolerance, and immune resilience.

Our goal is to translate these insights into meaningful clinical impact by identifying diagnostic markers, prognostic indicators, and therapeutic targets rooted in host–microbe interactions.

We investigate how diet, HLA genetics, sex hormones, and environmental exposures disrupt or restore this delicate balance. By integrating microbiome science, immunology, metabolomics, and genetics, we aim to advance a future where microbiome-guided diagnostics and interventions help rebuild immune homeostasis and improve the lives of people with MS and other chronic inflammatory diseases.

Mangalam Lab finds association between microbial ratio in gut microbiome with multiple sclerosis

Thursday, July 31, 2025
Researchers in Ashutosh Mangalam, PhD’s research laboratory, in collaboration with University of Iowa College of Nursing, University of Iowa College of Public Health, and University of Iowa Department of Neurology, have identified a microbial ratio in the gut microbiome associated with multiple sclerosis and disease severity.

Mangalam Lab’s research uncovering a key link between gut microbiota and multiple sclerosis (MS) is featured in The Conversation U.S.

Wednesday, March 26, 2025
A recent article in The Conversation U.S. highlights cutting-edge research from the Mangalam Lab in the Department of Pathology at the University of Iowa, based on their newly published study in PNAS. The study uncovers a key link between gut microbiota and multiple sclerosis (MS), identifying a specific bacterial ratio that may act as a biomarker for the disease and help predict its severity.
