Rethinking de novo immune hepatitis, an old concept for liver allograft rejection: Relevance of glutathione S-transferase T1 mismatch

Figure 5 CD138⁺ plasma cells were quantified in the diagnostic biopsies of the 7 patients (A). The results are shown as number of cells per mm²/tissue. IgG4⁺ plasma cells were also counted and subtracted from the total number of CD138⁺ cells. B: The same results are represented as percentages. C: Level of anti-GSTT1 antibodies in serum samples close to the diagnostic biopsy of 7 patients with dnAIH; note that only IgG1 and IgG4 were present whereas IgG2 and IgG3 were absent. It is important to highlight that these are donor-specific antibodies.
