From Lab to Life: Advancing Allergy Research in Luxembourg

Dr. Annette Kuehn, Principal Investigator and Group Leader for Molecular and Translational Allergology at the Luxembourg Institute of Health (LIH), Department of Infection and Immunity, tells us about the latest advances in allergy research and how they are shaping safer, more personalised care for families living with food allergies.


Can you explain what “Molecular and Translational Allergology” means in everyday language?

 Our group name reflects our research approach. 
“Molecular” describes what we study. We look at tiny building blocks such as antibodies, proteins, and cells.
“Translational” explains why we do this work. We want our findings to lead to better care for patients.
“Allergology” shows which medical field we focus on. We apply our approach to understanding and improving the science of allergies. 

Why is allergy research important for families living with food allergies today?

Allergy research is essential because it provides the evidence needed to create better medical solutions for families living with food allergies. Although “food allergy” sounds like one condition, every patient is different. Research helps to understand these differences - why allergies develop, why reactions vary, and how symptoms change over time. With this knowledge, new diagnostic tests and treatments become available, which make everyday life safer for affected families.  

What kind of allergy research is currently being carried out at the Luxembourg Institute of Health? 

My research includes the following main research topics. We are …

  • studying how the immune system changes in children with nut allergies during treatment to find better ways to track and treat the allergy.
  • testing whether giving tiny amounts of certain foods early in life can reduce allergy risk and looking for early signs that show if it works.
  • creating tools to predict whether new foods might trigger allergies by studying how human immune cells react to them.
  • exploring how gut bacteria and substances in stool affect food allergies to learn how a healthy gut may help prevent or improve them.
  • finding new environmental allergens that may increase with climate change and developing tests to diagnose them more accurately.

What does “translational” research mean for patients? How does research in the lab eventually benefit families?

Translational research means using what we discover in the lab to create real improvements for patients, with the ultimate goal of helping them return to a healthy life. It takes time for discoveries made in the lab to directly benefit families. During this process, patients may take part in clinical studies like the ones we conduct at LIH. Their participation is incredibly valuable because it helps researchers understand food allergies better and develop new solutions.

Are there any promising developments in early diagnosis or prevention of food allergies?

There have been several promising developments in recent years. Today, we already have more accurate and safer diagnostic tests, and researchers are getting closer to predicting allergy risk early in life. One of the biggest advances is the finding that introducing allergenic foods early in babies can help reduce the risk of developing food allergies. We also now understand much better how good nutrition and a healthy gut support the immune system and help prevent allergies. 

Looking ahead: What gives you hope for the future of allergy research?

Our early‑life environment plays an important role in whether a child develops food allergies. In recent years, we’ve learned much more about how microbes, pollutants, and everyday lifestyle factors can influence allergy risk. Many researchers around the world are working on this, and progress is happening quickly - that gives me a lot of hope.

Allergen Introduction in Everyday Life: a Parent’s Story

Image
In this interview, Lynn, mum of 3.5-year-old Julia and a member of the Luxembourg Allergy Network (LAN), shares her family’s journey with early allergen introduction and immunotherapy.   Can you briefly tell us your daughter’s allergy story? Julia was fully breastfed for the first six months of her life and started solids at around 6.5 months. When she was nine months old, she tried omelette for the first time. She sucked on it, and I noticed a rash on her neck. Because she was wearing a new plastic bib, I initially thought it was a reaction to the plastic. On Julia’s first birthday, I prepared noodles with boiled egg. This time, she immediately developed a rash all over her body, her eyes became swollen, and she vomited. That’s when I made the connection to egg. We consulted our paediatrician, who carried out a blood test. The results came back positive for egg and all tree nuts, and we were given an emergency medication kit. Later, we saw a specialist who carried out further test...

Interview with a paediatric allergist: Dr. Morel

Image
What are the first signs that a child might have a food allergy and when and where should parents seek testing? Early signs of food allergies in infants   According to Dr. Morel, paediatric allergist at the CHL Kannerklinik in Luxembourg, one of the earliest signs that may indicate a food allergy in infants is  moderate to severe atopic dermatitis (eczema)  that does not improve despite regular use of moisturising creams.   Other possible warning signs include  digestive symptoms , such as repeated vomiting, feeding difficulties, excessive crying, or poor sleep. Parents should also pay attention to  changes in their baby’s behaviour , as discomfort or pain may present in subtle ways.   Which children are at higher risk?   Some infants have a higher risk of developing  IgE-mediated food allergies .  (IgE allergies are “immediate” allergies caused by the immune system producing IgE antibodies, which can lead to quick reactions such as hive...
