Researchers at Mount Sinai have uncovered a groundbreaking method that could transform diabetes care forever. This discovery could lead to a simple pill capable of reprogramming the body to produce insulin, offering hope to over 500 million people worldwide living with diabetes.
Dr. Esra Karakose, a lead researcher at the Icahn School of Medicine at Mount Sinai, emphasized the revolutionary potential of this approach:
“This is an exciting finding that shows harmine-family drugs may be able to induce lineage conversion in human pancreatic islets.”
The Problem: A Global Diabetes Epidemic
Diabetes affects 537 million people globally, with both Type 1 and Type 2 diabetes stemming from the inability of pancreatic beta cells to produce insulin. Current treatments manage symptoms but don’t restore the body’s ability to produce insulin. Researchers have long searched for ways to regenerate or replenish these critical beta cells.
A Breakthrough Years in the Making
Mount Sinai’s journey began in 2015 when researchers discovered harmine, a DYRK1A inhibitor capable of stimulating beta cell regeneration. Since then, the team has advanced the science, demonstrating in 2019 and 2020 that harmine works synergistically with GLP-1 receptor agonists like semaglutide and exenatide to enhance beta cell regeneration.
In July 2024, researchers reported astonishing results:
- Harmine alone increased human beta cell mass by 300%.
- When combined with a GLP-1 receptor agonist, the increase soared to 700%.
An Unexpected Reservoir of Potential
The most exciting discovery? Alpha cells, another type of pancreatic cell, may hold the key to creating new beta cells. These alpha cells are abundant in diabetic patients and could be reprogrammed to produce insulin.
Using single-cell RNA sequencing technology, researchers analyzed over 109,881 individual cells from pancreatic islets donated by adults. They identified “cycling alpha cells,” which demonstrated potential to transform into beta cells.
“It may mean that people with all forms of diabetes have a large potential ‘reservoir’ for future beta cells, just waiting to be activated by drugs like harmine,” said Dr. Karakose.
How It Works: The Science Behind the Pill
The research focused on stimulating alpha cells to take on beta cell characteristics. The team observed that small-molecule drugs increased the number of cycling alpha cells while triggering them to produce insulin-related markers.
The findings suggest that, with the right drugs, alpha cells could replenish beta cells—potentially eliminating the need for insulin injections.
Challenges and Limitations
While the results are promising, the study is still in its early stages:
- The sample size was small, involving only four donors.
- Experiments were conducted in a lab setting, not in living humans.
- The long-term stability of newly formed beta cells remains unconfirmed.
Despite these challenges, researchers are optimistic about the next steps, including human trials.
What’s Next? Moving Toward Human Trials
Mount Sinai researchers are working to translate their findings into a treatment accessible to millions. Combining harmine with a GLP-1 receptor agonist could pave the way for a scalable, affordable pill.
Dr. Andrew F. Stewart, director of the Mount Sinai Diabetes, Obesity, and Metabolism Institute, remarked:
“A simple pill, perhaps together with a GLP1RA like semaglutide, is affordable and scalable to the millions of people with diabetes.”
A Revolutionary Shift in Diabetes Care
If successful, this approach could:
- Restore natural insulin production.
- Eliminate the need for daily injections.
- Offer a simpler, more effective treatment for both Type 1 and Type 2 diabetes.
This breakthrough represents not just a scientific achievement but a beacon of hope for millions managing diabetes.
