Study Reveals Clues About the Genetic Control of Immune Cells
More than 200 genetic variations can affect your risk of developing Crohn's or Colitis. However, scientists have been unable to figure out what these variations do, or why they contribute to someone developing Crohn's or Colitis. This type of research is very technically difficult, and until recently researchers could only study one genetic variation at a time, making progress very slow.
James and his team have overcome this by using a new technique to simultaneously test the effect of many genetic variations directly in immune cells. This gave them a really powerful tool to test their ideas about what causes the damaging inflammation seen in Crohn's and Colitis. Importantly, in their recent publication back in April they describe how one particular genetic variation leads to uncontrolled inflammation, which explains why this genetic variation predisposes people to immune-mediated diseases like Crohn's and Colitis.
The success of genetic studies in Crohn’s and Colitis has provided an incredible opportunity to better understand these diseases, but the complexity of figuring out how genetic variations predispose to disease had been a major obstacle for everyone in the field. We were delighted to have found a way to overcome this and can now use this approach to gain new insights into disease biology. This work could not have been done without the generous funding from Crohn’s and Colitis UK.
This work has opened the door to better understanding of the biology underlying inflammatory bowel diseases (IBD). The team hope that this will help identify new therapeutic targets and, in turn, speed up the development of better treatments. Indeed, James and his team have developed partnerships with pharmaceutical companies to take this idea one step closer to patients.
James and his team successfully show that the intelligent application of new techniques can reveal so much about disease biology.
Using this genetic technique to identify causes of inflammation in Crohn's and Colitis is particularly exciting because new drug targets that have been developed from genetic analyses are much more successful in clinical trials than those that weren't. We hope that by funding James' work we have helped open the door to new therapeutic opportunities for these conditions.

Helpline Service
Temporary closure - 10/06/2026
Our Helpline will be closed from Wednesday 10 June and will reopen at 10am on Monday 15 June.
We may be closed but we have lots of information here on our website.
If you need urgent medical advice you can call NHS 111 or in Northern Ireland phone your local Phone First. In an emergency call 999 or go to your nearest A&E.
If you need emotional support the Samaritans are available 24 hours a day, 7 days a week on 116 123.
We know it can be difficult to live with, or support someone living with Crohn’s or Colitis. But we’re with you. We can give you the right information and support at the right time.
We’re here for everyone.
How Can We Help?
- We can help you understand Crohn’s and Colitis
- Listen and talk about living with IBD
- Help you connect with others in the Crohn’s and Colitis community
- Give you contact details of specialist organisations
- We can support you to live well with Crohn’s or Colitis and provide up-to-date, evidence-based information
Please be aware we’re not medically or legally trained. We cannot provide detailed financial or benefits advice or specialist emotional support.
Please contact us via telephone, email or LiveChat - 10am to 3pm, Monday to Friday (except English bank holidays).
If you need specific medical advice about your condition, your GP or IBD team will be best placed to help.
