Immunostaining features of perforin, granzyme B and TIA-1 in lobules. The expression of perforin (A) and granzyme B (B) in lobules of biopsies without ACR is sporadic and significantly less than that with ACR (D and E, respectively). However, the expression of TIA-1 in lobules of biopsies without ACR (C) is prevalent, more than that with ACR (F). (Immunostaining with hematoxylin counter staining, ×400).
