Résumé
We present a 2-year serologic analysis of severe combined immune deficiency (SCID) mice populated with human peripheral blood leukocytes (PBL, hu-PBL-SCID mice). After 10-20 x 10(6) PBL transfer, human IgG serum levels generally increased in the SCID mouse recipient for 2 months, and thereafter decreased without returning to zero for at least 2 years. Great variability existed between different hu-PBL-SCID mice with regard to Ig serum levels even when derived from the same donor's PBL aliquot. The ratio of IgM to IgG serum levels was lower in hu-PBL-SCID mice than in the donors. The half-life of human IgG in the SCID mouse is shorter than in the human (8 days vs 23 days), suggesting a much higher production of IgG than expected from serum levels. The majority of hu-PBL-SCID mouse sera analyzed by high resolution electrophoresis had a smear appearance suggestive of diverse human Ig, generally with superimposed multiple faint mIg. Few mice developed strong human mIg, associated with lymphoproliferative diseases. In the hu-PBL-SCID mouse model, the transfer of cells from donors making antibody with defined specificity against TT and nuclear antigen resulted in the appearance of these antibodies in only a minority of the recipients.
