Liver HLA-E Expression Is Associated with Severity of Liver Disease in Chronic Hepatitis C

Figure 5

Association between HLA-E expression in Kupffer cells and liver necroinflammatory activity. HLA-E expression was described in the following grades: 0 (without positive cell expression), 1+ (<25%), 2+ (25–50%). There was no grade 3+ expression in this case. Necroinflammatory activity was described according to the METAVIR classification: A0 + 1: no or mild activity, A2: moderate activity, A3: severe activity. .
