Potential Compound May Eventually Suppress Severe Inflammatory Responses Linked to Conditions Such As IBS and Asthma
Mast cells, an essential part of our immune system, protect us from viruses, bacteria, and harmful substances from snake and insect bites. When activated, they can produce mucus, cause swelling and itching, and contract muscles in our airways, stomach, and intestines. Overactive mast cells lead to allergic reactions, including severe and difficult-to-treat conditions.
A groundbreaking study published in Signal Transduction and Targeted Therapy reveals a compound that blocks mast cells from leading particularly hard-to-treat and sometimes life-threatening reactions. These include irritable bowel syndrome (IBS), asthma, chronic itching, and migraines. Once considered pseudo-allergic reactions, these conditions are now classified as a type of allergy, as detailed in the study. The compound shows great potential in significantly reducing symptoms and thus lowering the risk of fatality.
Researchers, led by Christa Müller from the University of Bonn, identified a receptor named MRGPRX2 in the mast cells' membrane that triggers these hard-to-treat conditions when certain molecules attach to it. To prevent this reaction, the receptor must be blocked. After testing over 40,000 compounds, the team discovered a molecule that binds to the receptor and effectively switches it off.
The researchers developed a substance from this molecule, which remains effective at extremely low doses and has proven its efficacy in eliminating life-threatening allergic reactions in lab mice and blocking the MRGPRX2 receptor on isolated human mast cells. Importantly, the molecule only blocks the intended receptor, minimizing the risk of side effects.
Although Müller, Al Hamwi, and their colleagues have since improved the substance's efficacy and duration, more animal and eventually human trials are needed before it can be approved and commercialized as a drug. Despite this, its potential impacts on patients with some inflammatory conditions and those at risk of anaphylactic shock cannot be understated.
