While, we were unable to KIR genotype the present patient cohort, to allow us to precisely examine KIR2DL2 expression, we did observe maintenance of KIR2DL3 expression and down-regulation of KIR2DL1 and KIR3DL1 in chronic hepatitis C compared to healthy controls (Figure 1C). The gene discussed is KIR2DL1; the disease is chronic hepatitis C virus infection.
