Abstract

Immune cell populations in 8 diffuse histology B-cell lymphomas were analysed in frozen tissue sections by indirect immunofluorescence to gain insight into their possible modulating influence in these tumors. Use of monoclonal antibodies to identify cellular and extracellular antigens combined with nuclear counterstaining allowed precise quantitation, localization and comparison of T- and B-lymphocyte populations. T lymphocytes clustered in non-random fashion. Areas of high T-lymphocyte density manifested higher T4:T8 ratios than locales with fewer T lymphocytes (p < 0.05). Few cells had surface antigens (Leu 7, 73.1, OKM1) associated with natural killing. Cells strongly reactive with anti-TAC (Interleukin-2 receptor, associated with T-lymphocyte activation) were also T11 reactive and were usually helper (Leu 3) phenotype. In addition, B-lineage lymphoma cells in some tissues reacted with anti-TAC. The pattern of tumor cell reactivity with anti-TAC correlated with Rappaport histologic classification. These findings suggest that non-malignant T lymphocytes modulate B-lymphoma cell growth in situ, and that in some lymphomas the T-cell product IL-2 may be an important local growth factor.
