To assess the possible role of TREM1 in viral hepatitis, we first determined the plasma levels of sTREM1 in patients infected with the hepatitis B virus (HBV; n = 34) or with the hepatitis C virus (HCV; n = 29) and healthy subjects (n = 17); the patient characteristics are depicted in Table 1. The gene discussed is TREM1; the disease is animal viral hepatitis.
