THE ROLE OF HUMORAL ANTIBODIES IN REJECTION OF SKIN HOMOGRAFTS IN RABBITS : I. PASSIVE TRANSFER OF ISOIMMUNE SERUM TO CONDITIONED HOSTS.
Gross and microscopic observations of skin homograft rejection carried out in cortisone-conditioned and non-conditioned rabbits seem to indicate that humoral antibodies play an important role in the phenomenon. Thus, local administration of isoimmune serum to animals bearing skin homografts resulted in a significantly earlier rejection of that particular test graft without modifying the course of a neighboring control-skin graft. This result appears to support the idea that homograft rejection is not only due to cellular antibodies but to a combination of both humoral and cellular immune responses, which should not be regarded as completely unrelated.
