Infected lung tissue

Caption

View of infected lung tissue (image A). As early as the second day post infection, SARS-CoV-2 (red) invades nearly all areas of the lungs. This has a negative impact on lung function. The virus invades and destroys both the cells lining the respiratory tract (B, arrowhead icon) and the cells responsible for gas exchange, which line the alveoli (known as type I and type II pneumocytes, see arrow pointers in). Large quantities of virus particles can be detected inside the lung’s macrophages (immune cells which are the ‘big eaters’ of the immune system) (E, arrowhead icon). Bars: B = 50 µm, C - E = 20 µm
