Immunohistochemical detection of IGF-2R and granzyme B-positive T lymphocytes. Representative immunohistochemical staining on the serial sections from biopsies with rejection grade 3 from patients #6 (A) and from biopsies with rejection grade 2 from patient #4 (B) at the 3rd month after heart transplantation showed coexistence of IGF-2R and granzyme B-positive T lymphocytes, accompanied by mononuclear cell infiltration with myocyte damage in the same sites in haematoxylin and eosin (HE) staining.
