| Abstract: | Cells from malignant lymphoma in 10 rhesus macaques were examined for lymphocyte surface markers. Three had features of T cells, 5 had features of B cells, and 2 lacked evidence of either B- or T-cell differentiation. Correlation between the histologic classification of cell type and the B- or T-cell nature of the neoplasms was not evident. Evaluation of serum electrophoresis, mitogen responses tests, and previous histologic studies suggest that the development of the neoplastic lymphocyte proliferation occurred following or during an abnormal immunologic response. |
