(Press-News.org) BOSTON, MA – June 25, 2025 – The Lupus Research Alliance (LRA) proudly awarded the 2025 Lupus Insight Prize today to highly respected immunologist Deepak Rao, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School. The Prize recognizes Dr. Rao’s pioneering and widely reported findings published in Nature, which reveal a previously unknown imbalance in key immune cells that contribute to lupus. The study sheds light on how this imbalance arises and identifies a potential target for restoring immune system regulation in people with the disease.
Dr. Rao was honored today at the Federation of Clinical Immunology Societies (FOCIS) 2025 meeting in Boston, Massachusetts, in a ceremony chaired by Gary Koretzky, MD, PhD, Weill Cornell Medicine, and Co-Chair of the LRA Research Committee of the Board of Directors. The prestigious $100,000 Lupus Insight Prize is presented to outstanding investigators who have made significant scientific breakthroughs in the last five years that advance the understanding of lupus and have the potential to drive new lupus treatments.
“We’re starting to understand the core features of the immune response that gets activated in lupus,” noted Dr. Rao. “The Lupus Insight Prize will allow us to continue to identify key signals and pathways that drive the damaging immune response. We hope to use this knowledge to design new strategies to rebalance the immune system in patients with lupus to suppress damaging pathways and promote protective ones.”
AHR and JUN: Newly Discovered Drivers of Immune Imbalance in Lupus
Lupus is driven by an overactive immune system that mistakenly targets a person’s own cells and tissues. Dr. Rao’s research focuses on two types of immune cells—T peripheral helper (Tph) and T follicular helper (Tfh) cells—that help B cells produce antibodies. In close collaborative work between Dr. Rao and Dr. Jaehyuk Choi, MD PhD, a dermatologist and immunologist at UT Southwestern, Drs. Rao and Choi found that in lupus, these B-helper T cells are abnormally abundant, while another type of T cell, called Th22, is reduced. This imbalance contributes to excessive B cell activation and inflammation.
Their research identified a key factor behind this shift: a regulatory pathway involving the proteins AHR and JUN. Normally, AHR and JUN help maintain a balance between these T cell types, preventing excessive immune activation. However, in lupus, inflammatory signals—particularly from interferons—disrupt this regulation, reducing the number of protective Th22 cells and allowing harmful B-helper T cells to dominate.
By pinpointing this mechanism, the study results suggest that restoring AHR-JUN signaling could help rebalance the immune system and reduce lupus-related inflammation. This discovery provides a promising new direction for therapeutic development.
“The Lupus Insight Prize recognizes discoveries that have the power to change the course of lupus research,” said Teodora Staeva, PhD, Chief Scientific Officer at the LRA. “Dr. Rao’s work has uncovered a critical piece of the immune system’s dysfunction in lupus, bringing us one step closer to targeted therapies that can restore balance.”

About Lupus
Lupus is a chronic, complex autoimmune disease that affects millions of people worldwide. In lupus, the immune system, meant to defend against infections, produces autoantibodies that mistake the body’s own cells as foreign, causing other immune cells to attack organs such as the kidneys, brain, heart, lungs and skin, as well as blood and joints. Ninety percent of people with lupus are women, most often diagnosed between the ages of 15-45. Black, Latinx, Indigenous, Asian and Pacific Islander people are disproportionately affected by lupus.
About the Lupus Research Alliance
The Lupus Research Alliance is the largest non-governmental, non-profit funder of lupus research worldwide. The organization aims to transform treatment by funding the most innovative lupus research, fostering scientific talent, and driving discovery toward better diagnostics, improved treatments and ultimately a cure for lupus. Because the Lupus Research Alliance’s Board of Directors funds all administrative and fundraising costs, 100% of all donations goes to support lupus research programs.

NAU researchers launch open-source robotic exoskeleton to help people walk
2025-06-25
Imagine a future in which people with disabilities can walk on their own, thanks to robotic legs. A new project from Northern Arizona University is accelerating that future with an open-source robotic exoskeleton.
Right now, developing these complex electromechanical systems is expensive and time-consuming, which likely stops a lot of research before it ever starts. But that may soon change: Years of research from NAU associate professor Zach Lerner’s Biomechatronics Lab has led to the first comprehensive open-source exoskeleton framework, made freely available to anyone worldwide. It will help overcome several huge obstacles for potential ...
Early farmers in the Andes were doing just fine, challenging popular theory
2025-06-25
In the Andes, the rise of agriculture to replace foraging was not the result of hardship and resource scarcity, but instead a time of economic resilience and innovation, according to a study published June 25, 2025 in the open-access journal PLOS One by Luis Flores-Blanco of the University of California Davis and Arizona State University, U.S., and colleagues.
The transition from foraging to farming was a major shift in human history that laid the foundations for the expansion of modern civilization. The current prevailing ...
Seeing men as the “default” may be tied to attitudes to politicians, Black people
2025-06-25
In an international study, participants’ attitudes towards certain social groups—namely, politicians and Black people—were more strongly related to their attitudes towards the men than the women of each group, suggesting that men are the “default” for attitudes towards these groups. Curtis Edward Phills of the University of Oregon, U.S., and colleagues present these findings in the open-access journal PLOS One on June 25, 2025.
Prior research has shown how people often discuss some social groups as though they are primarily made up ...
Risk of crime rises when darkness falls
2025-06-25
A U.K. study of data on more than 30,000 crimes sheds new light on crime after dark, suggesting that the overall risk of crime rises when darkness falls, but that risk varies depending on type of crime and geographical area. Jim Uttley of the University of Sheffield, U.K., and colleagues present these findings in the open-access journal PLOS One on June 25, 2025.
Prior research has shown that darkness reduces people’s feelings of safety, and that improved street lighting can help people feel safer being out after dark. However, research on whether the risk ...

"Shrinking" cod: how humans have altered the genetic make-up of fish
2025-06-25
Cod used to be giants. With their impressive size — over a metre in length and weighing up to 40 kilograms — and abundance, they, alongside herring, were the backbone of the Baltic fishery. Today, a fully grown cod would fit neatly on a dinner plate. That is, if fishing them were still permitted: due to the collapse of the stock, a ban on targeted cod fishing has been in place since 2019.
The shrinking of the cod population, in terms of both number and in size, is the result of human influence. In their new study, scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have demonstrated ...
Nitrate in drinking water linked to preterm birth rates
2025-06-25
Even low levels of nitrate—a common agricultural runoff and drinking water contaminant—are associated with increased risks of preterm birth and low birthweight babies, according to a new study published June 25 in PLOS Water by Jason Semprini of Des Moines University College of Health Sciences, US.
Nitrate is a naturally occurring compound increasingly found in inorganic fertilizers and, through runoff, in groundwater. When consumed by humans, nitrates can interfere with the blood’s capacity to ...
Ancient canoe replica tests Paleolithic migration theory
2025-06-25
When and where the earliest modern human populations migrated and settled in East Asia are relatively well known. However, how these populations moved between islands on treacherous stretches of sea is still shrouded in mystery. In two new papers, researchers from Japan and Taiwan led by Professor Yousuke Kaifu from the University of Tokyo simulated methods ancient peoples would have needed to accomplish these journeys, and they used period-accurate tools to create the canoes to make the journey themselves.
Evidence suggests that around 30,000 ...
