Ontogeny of the GVH-R inducing capacity, in conventional and germ-free chickens.
Three strains of MHC homozygous chickens were used to study the ontogeny of the GVH-R. It was found that this function of the immune system was acquired with a delay in animals raised in germ-free conditions. In our previous work, we had shown that, contrary to expectation, bursal cells were capable of mounting a GVH-R against embryos, and actually were particularly efficient in this regard when compared to spleen cells. The present experiments have disclosed that splenomegaly induction may be dissociated from the toxic effect that bursal cells also exert on recipient embryos.
