Abstract:
:The localization and distribution of gamma delta T cell receptor (TCR)-positive cells (gamma delta T cells) in hepatocellular carcinoma capsules was investigated immunohistochemically at both light and electron microscopic levels. Most of the mononuclear cells infiltrating the tumor capsules were CD3-positive. Together with gamma delta T cells, they were significantly increased in the tumor capsules compared to amounts in the fibrous septa in non-cancerous cirrhotic areas of the same liver, and compared to amounts in the liver of patients with cirrhosis. Phenotypic characterization by the two-color double-staining technique showed that CD8/gamma delta cells were significantly increased in the tumor capsule, and that more than one-third of gamma delta TCR-positive cells also expressed the CD56 antigen. Morphological observation revealed that large gamma delta T cells were increased in number in the tumor capsule and that the cytoplasm of these cells contained multivesicular bodies and dense granules. These morphological features were similar to those of large granular lymphocytes, and most of the gamma delta T cells were also positive for BB3. This suggests that extrathymic maturation of gamma delta T cells occurs in the tumor capsule, and that these gamma delta T cells may have a cytolytic effect on tumor cells, as shown in large granular lymphocytes; further, the results suggest that these cells may play a role in the defense against tumor expansion.
