title: Are serum antibody, complement or K-cell dependent cellular cytotoxicity involved in corneal graft rejection?
abstract: Having shown that complement independent cellular cytotoxicity (CICC) plays a part in destroying the donor cell we wished to see if serum antibody cytotoxicity (SAC), complement dependent cellular cytotoxicity (CDCC) or K-cell mediated cellular cytotoxicity (KCC) might not also be involved in the rejection of corneal grafts. Rabbits were grafted with allo- and xenogreneic corneas. At various times, lymphoid cells and sera were collected from a recipient and a control animal. The donor's corneal cells and those of the control animal were cultivated in vitro, and then labelled with 51chromium. The recipient and control lymphoid cells and sera and/or complement were mixed with the labelled cells. A 51chromium release assay was done after incubation. The test was negative for SAC, CDCC, and KCC and we feel that they have no major part in the rejection of corneal grafts.
