SUMMER NEWSLETTER 2025    
Dear Friends,

For the very first time – because of your support – Propel a Cure is sponsoring not one, not two, but three cutting-edge research projects that will help us get closer to understanding Crohn's disease.

These studies break the mold by focusing on players in Crohn's that have previously not been thoroughly investigated or understood. The data these labs acquire from these early-stage studies will help them verify hypotheses that in turn will potentially attract major funding leading to more effective therapies and eventually cures for patients!

We are very thankful to all of you and to the research teams leading these studies for your willingness to try to break beyond the status quo and what's been done before to give hope to those with Crohn's.




RESEARCH UPDATE
GHOSH LAB, UC SAN DIEGO
EFFECT OF MUTATION IDENTIFIED


This past April, Propel a Cure pledged $100,000 to the Ghosh Lab at the University of California, San Diego for a groundbreaking, cure-focused Crohn's disease study. Generous supporters have already donated $79,000 toward this project, which is now underway. You can make a big difference by helping fund the remaining $21,000 of this initiative at propelacure.org/donate. Every gift, regardless of size, counts!

This lab is already giving us a better understanding of Crohn's:

Researchers at Ghosh Lab at University of California, San Diego have made an exciting discovery that helps explain why some people with Crohn's disease have trouble clearing infections in their gut.

Over the past few months, the team has studied a special immune sensor inside cells called NOD2 and a helper protein named GIV. When working together, these two proteins help the immune system recognize harmful bacteria and get rid of them properly—keeping inflammation under control. But when either of these proteins isn’t working, the gut has trouble healing, and inflammation can get out of hand.

To understand this better, the team worked with mice and immune cells called macrophages. Mice that didn’t have GIV developed a type of gut disease that looked very similar to Crohn’s disease in humans, including swelling, tissue damage, and problems with the natural balance of gut bacteria. Most importantly, the team focused on a common version of NOD2 called "1007fs", which is found in many Crohn's patients. This version is broken—it’s missing a key piece—and the researchers have now found out why that matters: It can't connect to GIV. Without that connection, the immune system can't do its job right, and bacteria aren't cleared properly. This leads to more inflammation and damage in the gut.

This is the first time scientists have clearly shown how this precise Crohn's risk mutation, which was discovered originally in 2000, disrupts the immune system's ability to clear bacteria.

Now that the team understands this key piece of the puzzle, they are excited about the next step: exploring ways to fix or replace this broken connection between NOD2 and GIV as a new way to treat Crohn's disease. Beyond mice, this team has the unique ability to test all their findings and hypotheses as well as potential drug-like small molecules and peptides in mini human guts called organoids. The team plans on doing those studies next. Hence, this foundational discovery opens up new doors for treatment, and it gives hope that future therapies could help restore balance in the gut and reduce inflammation—right at the source.

RESEARCH UPDATE
WOOLSTON LAB, NORTHEASTERN UNIVERSITY
TOOL TO TEST MICROBE IN CROHN'S
Earlier this year, Propel a Cure, in partnership with the Mendez Family Foundation, contributed $100,000 to a project at the Woolston Lab at Northeastern University to determine the role of the gut microbe hydrogen sulfide (H2S) in intestinal inflammation in inflammatory bowel disease (IBD), potentially paving the way to a new nonimmunosuppressive therapeutic that could treat Crohn's disease. The team first engineered bacteria in the lab to try to produce excess H2S in the animal gut. After giving their engineered bacteria to animals, they observed a greater than 5-fold increase in intestinal H2S.

This is a critical milestone because elevating H2S levels is experimentally difficult due to its gaseous nature. The team now has a tool capable of elevating intestinal H2S levels – mimicking what is seen in Crohn's patients – that will help us understand its fundamental role.

In the next phase of this work, the Woolston Lab will be able to use their engineered bacteria to study how high levels of H2S impact Crohn's pathology, which is a significant step forward.

RESEARCH UPDATE
PROMAKHOS THERAPEUTICS
THERAPEUTIC TESTED IN MICE
Boston-area Promakhos Therapeutics is pursuing a study, funded in part by Propel a Cure, investigating what they believe to be a deficiency in the mucosal innate immune response in Crohn's patients and an oral, nonimmunosuppressive therapy to correct it.

Over the past few months, the researchers transplanted stool from patients with active Crohn's disease and reduced levels of the innate immune-activating molecules into mice to establish a humanized mouse model of bowel inflammation. Encouragingly, the team observed that mice transplanted with stool from patients showed a 4-fold reduction in fecal levels of the bacterial molecules, as compared to mice transplanted with stool from healthy individuals.

Once the Crohn's patient gut microbiome was established in the mice, the researchers induced acute colon inflammation to evaluate the therapeutic effect of their compound. In this model, inflammation worsens for 3-4 days and then heals over the next 10 days or so. Starting at the peak of inflammation (Day 4), the researchers administered their compound once per day through the mouth to restore the natural activity of the bacterial molecules in the mouse gut.

Although the study has not been finalized, the team is excited to share that the administration of their therapeutic compound led to a reduction in symptoms by 73% on Day 8 and by 92% on Day 10, while placebo-treated mice showed a 43% and 67% reduction by Days 8 and 10, respectively. These differences were statistically significant, suggesting that the restoration of the natural levels of the bacterial molecules with their compound greatly accelerated healing of acute colon inflammation in these mice.

The next steps are to further analyze the results of this study and to explore different doses of this compound in this new Crohn's patient humanized mouse model.
INTERVIEW
DR. JOANA TORRES
IBD PREDICTION & PREVENTION
In our recent virtual discussion with Dr. Joana Torres, she brings us up to date on the latest in IBD prediction and prevention! In this video, she shares the remarkable headway that researchers are making in predicting disease risk years before onset, as well as how we may eventually even be able to stop IBD before symptoms begin. She further explains how preventive treatments may someday lead to new therapies for those patients with established disease.

Dr. Torres is based at Hospital Beatriz Ângelo (Loures, Portugal) and Hospital da Luz (Lisbon) as a Consultant in Gastroenterology, where she oversees the IBD clinic, actively combining clinical practice with research and teaching. Her research focuses on populations at risk for IBD and newly diagnosed IBD, with the aim of finding predictors of IBD development and disease course. She is involved in several large projects in this sphere, including the potential development of preventive interventions, such as the PREDICT study, the EARLY-CD study, the GlycanTrigger project, and the large European Union-funded INTERCEPT study.

PERSONNEL CHANGES
Angela Clark Raihaneh Bokharai
Propel a Cure is pleased to announce some changes to the organization's Board of Directors, which also serves as its all-volunteer operational staff.

First, we will be forever grateful to Founder Annabelle Hall, whose drive to find answers for her son after he was diagnosed with Crohn's disease led to the founding of our organization in the quest to fund innovative scientific research to uncover the causes of Crohn's disease and push for cures.

This past April, after eight years of tireless efforts and helping Propel a Cure become a force for change in Crohn's research, Annabelle made the decision to retire and, in consultation with the Board, named Angela Clark as its new President and CEO.

Angela, who worked closely with Annabelle after joining Propel a Cure in 2019, became involved after the Crohn's diagnosis of a family member. In the past, she enjoyed a career in the federal government as well as working in local radio and television. She feels passionate about supporting Crohn's research that takes us beyond the current therapy landscape, and hopes to prioritize spreading Propel a Cure's message to a wider audience as well as expanding the number of cure-focused studies the nonprofit is able to sponsor.

Propel a Cure would also like to welcome its newest and first Europe-based Board member, Raihaneh Bokharai, our Vice President of Strategic Partnerships. Raihaneh is a strategic consultant with a diverse background spanning both the for-profit and nonprofit sectors.

Raihaneh received her bachelor's degree in social work from Saxion University of Applied Sciences and is currently completing a master's in management with a specialization in strategy & innovation at the Open Universiteit. Based in the Netherlands, Raihaneh became a patient after her IBD diagnosis. She is a strong proponent of Propel a Cure's goal-oriented approach of supporting innovative research and brilliant scientists working to advance tangible progress toward a cure for Crohn's disease in the hope of bringing relief to those affected.
