FAS and Cirrhosis: These results corroborate those of Peter et al.: they observed low constitutive expression of CD95 in non-cirrhotic patients with chronic HBV, compared to patients with cirrhosis related to HBV.8 The results obtained in this study agree with literature that CD95 is overexpressed during HBV infection.9 The expression of CD95 increases in response to a primary stimulus and this makes hepatocytes more susceptible to stimulation by CD95L.
