Indian American researcher gets $4M NIH grant to study autoimmune disease

A major breakthrough in autoimmune disease research could move medicine closer to preventing illnesses before they develop, as Indian-origin biomedical scientist Chandra Mohan has secured a $4 million grant from the National Institutes of Health to investigate the earliest biological signals that trigger chronic autoimmune disorders.

Mohan, a distinguished professor at University of Houston, will lead a 10-year longitudinal research project designed to understand how the immune system gradually begins attacking the body's own healthy tissues long before patients experience noticeable symptoms.

The study will focus on Systemic Autoimmune Rheumatic Diseases (SARDs), a category that includes conditions such as Lupus, Rheumatoid arthritis, Sjögren syndrome, and Systemic sclerosis. Together, these disorders affect more than 30 million people worldwide, often causing lifelong inflammation, organ damage, fatigue, and recurring disease flare-ups.

Unlike current medical approaches that diagnose autoimmune diseases only after significant tissue damage has occurred, Mohan's research seeks to identify the earliest molecular, genetic, and environmental changes that occur before disease symptoms appear. Researchers will analyze blood samples alongside environmental exposure data to determine precisely when immune tolerance begins to fail.

Scientists believe that discovering these early warning signals could eventually make it possible to diagnose autoimmune diseases years before they become clinically visible. Such findings may pave the way for preventive therapies capable of stopping disease progression before permanent damage occurs.

The project also brings together leading experts in autoimmune medicine, including collaboration with Karen Costenbader of Harvard Medical School, combining expertise in immunology, rheumatology, and biomedical engineering.

Mohan's academic journey reflects decades of international medical and scientific training. He earned his medical degree from the National University of Singapore before completing specialty training in pathology and rheumatology at Singapore General Hospital. He later pursued doctoral research at Tufts University, followed by postdoctoral work at Northwestern University Feinberg School of Medicine, and previously held the prestigious McGee Chair in Arthritis Research at UT Southwestern Medical Center.

Medical experts say the NIH-funded project could fundamentally transform the future of autoimmune care by shifting healthcare from treating disease after diagnosis to preventing illness before it begins. If successful, the research may improve outcomes for millions of patients while reducing the enormous long-term medical and economic burden associated with chronic autoimmune conditions.
