HLA-DRA and Sepsis: To determine whether ACLF patients did indeed suffer from immunosuppression, we measured the expression of miR-222, miR-221 (6), and HLA-DRA, which encodes the alpha subunit of HLA-DR and is routinely assessed as biomarker of immunosuppression in sepsis (2, 4, 5, 46, 48, 57) and cirrhosis (45).
