    The exchange of gas between the air we breathe and the blood is carried out through the alveoli, which are tiny air sacs


    Surfactants are secreted continuously in the lungs, while alveolar macrophages (AM) break them down and clear


    Professor Mildner, the corresponding author of the study, has been studying macrophages for 20 years


    The key role of transcription factor C/EBPβ

    Professor Alexander Mildner and Professor Achim Leutz chaired the study


    The researchers isolated alveolar macrophages from healthy mice and mice lacking the C/EBPβ gene and performed in vitro analysis


    An important mystery

    Molecular analysis further showed that in mice lacking the C/EBPβ gene, another transcription factor, PPARg, was also downregulated


    Alveolar protein deposition is the result of


    Therefore, C/EBPβ appears to be a missing link


    What are the keys to understanding other diseases?

    Macrophages are scavengers of the immune system, but they do more than just remove bacteria and viruses


    Abnormal lipid metabolism is not only the root cause of alveolar protein deposition; It can also cause atherosclerosis, a serious vascular disease


    Professor Mildner said: "We believe that the signaling pathways we have revealed are also important


    For alveolar proteinosis, a new treatment is about to emerge
