LKM1 autoantibodies in chronic hepatitis C infection: A case of molecular mimicry?
Gabriel Marceau, Pascal Lapierre, Kathie Béland, Hugo Soudeyns, Fernando Alvarez – 21 July 2005 – Anti‐liver‐kidney microsome type 1 (LKM1) autoantibodies directed against the cytochrome P450 2D6 (CYP2D6) are considered specific markers of type 2 autoimmune hepatitis, but are also found in 5% of sera from patients chronically infected by hepatitis C virus (HCV). Molecular mimicry between HCV proteins and CYP2D6 has been proposed to explain the emergence of these autoantibodies.
