Histocompatibility antigens and genetic control of the immune response in guinea pigs IV. Specific inhibition of lymphocyte proliferation by auto-anti-idiotypic antibodies
AF Geczy
The in vitro T-cell proliferation induced by penicilloylated bovine IgG
(BPO-BGG) in sensitized strain 2 guinea pigs could be specifically blocked
by the serum of guinea pig (*305) which had been repeatedly immunized with
BPO-BGG over a period of 9 mo. The antibodies which appeared in the serum
of this animal (*305) were functionally similar to the strain 2
anti-idiotypic antibodies (a strain 2 BPO-BGG) raised by immunizing strain
2 guinea pigs with immuno-adsorbent column- purified BPO-BGG. Animal *305
had no detectable antibodies to BPO-BGG and failed to give a delayed
hypersensitivity skin response when challenged with BPO-BGG.
