Hepatic angiotensin-converting enzyme 2 expression in metabolic dysfunction-associated steatotic liver disease and in patients with fatal COVID-19

Figure 1 Angiotensin-converting enzyme 2 protein expression pattern in normal and metabolic dysfunction-associated steatotic liver disease livers. A: Representative images of angiotensin-converting enzyme 2 immunostaining across the metabolic dysfunction-associated steatotic liver disease histological spectrum. Scale bars: 200 µm; B: Representative views of boxed areas in panel A (positive and specific staining is indicated with arrowheads). Scale bars: 50 µm. MASH: Metabolic dysfunction-associated steatohepatitis; MASLD: Metabolic dysfunction-associated steatotic liver disease.
