The expression of TMPRSS2 remained unchanged in MASLD, whereas the MERS-CoV receptor dipeptidyl peptidase 4 (DPP4) and the SARS-CoV-2 coreceptor CLEC4M were lower in steatosis and steatohepatitis, with respect to controls (Fig. S8B). This evidence concerns the gene DPP4 and metabolic dysfunction-associated steatotic liver disease.
