The fungus Aspergillus fumigatus blocks messenger substances in the immune system
For healthy people, mold spores in the indoor air are normally no problem, since the pathogens are successfully controlled by the immune system. For certain groups, however, caution is required. The guideline of the Scientific Medical Societies (AWMF) includes people with a weakened immune system due to chemotherapy, stem cell transplants or HIV infections. Other risk groups include people with cystic fibrosis and bronchial asthma. The German Robert Koch Institute (RKI) divides the symptoms of immunosuppression into three groups and speaks of moderate, severe and very severe immunosuppression. In a recent study, scientists from the Friedrich Schiller University in Jena (Germany) have now found out in what way the mold can turn off the immune system.
