To evaluate cell-type-specific ACE2 receptor expression in healthy human liver tissue and clarify the mechanisms underlying coronavirus-associated liver impairment.
Analyzed single-cell RNA-sequencing (scRNA-seq) datasets of healthy human liver tissue across two independent cohorts.
Assessed cell-type-specific ACE2 expression across different hepatic cell populations, including hepatocytes and cholangiocytes.
Identified specific ACE2 receptor expression in cholangiocytes rather than hepatocytes in healthy liver tissue.
Indicated that liver impairment in infected individuals likely stems from cholangiocyte dysfunction, drug toxicity, or systemic inflammation rather than direct hepatocyte destruction.
