 AB    The distribution of subpopulations of lymphocytes in lymph nodes and
       tumors from cattle with enzootic bovine leukosis (EBL) was examined by
       immunohistochemistry using a panel of monclonal antibodies against
       leukocyte differentiation molecules of EBL. The lesions in lymph nodes
       could be divided into three types based on the extent of infiltration
       and proliferation of neoplastic cells with provirus and differential
       expression of leukocyte differentiation molecules. The number of B-B2+,
       sIgM+ cells was reduced in frequency in follicles during the neoplastic
       cell proliferation. CD4- and CD8-positive alpha/beta T cells and
       gamma/delta T cells positive for WC1 (workshop cluster designation) were
       also reduced in frequency in areas infiltrated with neoplastic cells.
       Almost all neoplastic cells were B-B2- and IgM-positive. However, there
       were a few B-B2- and/or IgM-negative cells or cells stained faintly in
       all cases. WC1+ cells were not observed in tumor tissues. However, CD4+
       and CD8+ cells were observed throughout tumor tissues, suggesting a role
       for these cells in tumor immunity.
