title: Lymphocyte-mediated lysis of autologous and allogeneic B-cell lines in man.
abstract: The lytic potential of human blood lymphocytes was assayed against autologous and allogeneic EBV-transformed B-cell lines (LCL). The effects--if present--were very weak. Short-term interferon (IFN) treatment of the lymphocytes induced cytotoxic potential which could be manifested against autologous and allogeneic LCL. The sensitivity of the targets increased after superinfection with the P3HR-1 strain of EBV. Thus the strongest lytic effects were obtained with IFN-treated lymphocytes acting on EBV superinfected targets. Individuals with and without previous EBV encounter reacted against autologous LCL, indicating that the lysis did not represent an EBV-specific cellular memory. No evidence for alloantigen recognition emerged from the tests.
