Figure 1 Typical diffuse staining of the cytoplasm of the entire liver lobule on rat liver sections in a case of autoimmune hepatitis type 2 positive for antibodies against liver-kidney microsomes type 1 (A); Antibodies against liver-kidney microsomes type 1 react to the proximal tubules of the rat kidney and the absence of reactivity against the distal tubules of the rat kidney (see also Figure 2) and parietal cells of the rat stomach distinguishes anti-LKM1 autoantibodies from antimitochondrial antibodies (B).
