  • Research summary

    Macrophages are immune cells which play key pathogenic roles in infectious and non-infectious diseases such as tuberculosis, influenza, asthma, metabolic conditions and cancer. One type of tissue resident macrophages, lung-alveolar macrophages (AMs) are vital in the normal functions of the airways and have significance in the pathogenesis of most human lung disorders. AMs derive from foetal monocytes which develop and mature by granulocyte-macrophage colony stimulating-factor (GM-CSF), a substance produced mainly in the lung. Since the availability of lung macrophages is limited, however, we established an in vitro model of non-transformed, GM-CSF-dependent mouse AM-like macrophages (MPI cells) to study lung diseases while reducing the need for living animals as well. The aim of the study here is to establish similar continuously growing human AM-like cell lines to better understand human lung diseases. For this purpose, we will culture leucocytes isolated from healthy human blood, cord blood or splenocytes obtained from healthy volunteers, pregnant females and tissue banks with GM-CSF to establish continuously growing cell lines in order to test them.
