Retrovirus-neutralizing antibodies in AML and AMMoL patients: stage-specific distribution.
Plasma samples of patients with AML or AMMoL were tested for antibodies reacting with gp70 antigens of BaEV and GaLV as well as for antibodies neutralizing BaEV or GaLV. Both frequency and titer values of antibodies were higher in remission than in blastosis. Neutralizing activity could be detected only in those plasma samples which contained antibodies to the appropriate gp70 antigen. The data suggest the presence of retroviruses in humans as antigenic stimuli for the immune system in AML and AMMoL.
