A study conducted by scientists from the Institut Pasteur has revealed that microbes protect the lungs from subsequently developing allergies and asthma. This long-term protection is "memorized" not by immune system cells, but by fibroblasts, structural cells in the lungs. These results, published in Nature Immunology, open up new possibilities for the development of preventive strategies for respiratory allergies.
