  • Abstract
  • Look Inside

Twenty-eight human brain tumors (18 gliomasand 10 metastatic brain tumors) were examined immunohistochemically using anti-Leu 1, -Leu 2 a, -Leu 3 a + 3 b, -LeuM 5, -HLA-DR, IL-2 receptor, -HLA-ABC and Ki-67 monoclonal antibodies (MoAb). Also, in the specimens, in which Leu 1+ cells and Leu M 5+ cells infiltrate, simultaneous detection of Leu 2 a, Leu 3 a + 3 b, or LeuM 5 and HLA-DR, was performed by double immunofluo-rescence staining to analyze the T cell activation and antigen-present macrophage (MO).

Most of low-grade gliomas with low percentage of Ki-67+ cells showed only little lymphocyte and Mqφ's infiltration. There was a tendency toward a marked degree of T cell and MO in-filtration in malignant glioma with higher percen-tage of Ki-67+ cells. However, in metastatic brain tumors, MO did not tend to infiltrate. IL-2 re-ceptor+ cells was absent in the majority of brain tumors. Tumor cells and vascular endothelial cells also expressed HLA-DR antigens. The majority of tumor cells expressed HLA-A, B, C antigens. There were no correlation among the degree of T cell and MO infiltration, MHC antigen expres-sion, and percentage of Ki-67+ cells. Double im-munofluorescence staining demonstrated that 42. 4 % of Leu 2 a+ cells, 34. 7% of Leu 3 a+ + 3 b+ cells and 32.7% of M5+ cells are HLA-DR positive in glioma, and that 50. 2% of Leu 2 a+ cells, 59. 4% of Leu 3 a+3b+ cells and 67. 3% of LeuM 5+ cells are HLA-DR positive in metastatic brain tumors.

Our results indicated that in gliomas activated T cells infiltrated in tumor tissues, or T cells in-filtrating tumor tissues were activated around blood vessels.
