Abstract
Rabbits thymectomized within 2 months after birth presented a more marked anti-hapten antibody response against DNP-BGG than non-thymectomized control animals. A reduction in anti-hapten response was observed in rabbits injected with allogeneic thymocytes, although it was of short duration. A marked reduction in anti-hapten response was observed in rabbits pre-immunized with the carrier, showing a sharp contrast with an ordinary response observed in the mouse.
The results mentioned above seemed to show the possibility that the immunological function of the rabbit T cells might be qualitatively or quantitatively different from that of the mouse T cells.
