Induction of corneal graft rejection by passive cell transfer

Investigative Ophthalmology
A A Khodadoust, A M Silverstein


An experimental model is presented demonstrating that penetrating corneal grafts in the rabbit may be rejected by passive transfer into the anterior chamber of specifically sensitized lymphoid cells. Destruction of histo-incompatible corneal endothelium is always marked by the formation of focal pock-like areas of damage in this system, rather than by the typical moving line of rejecting endothelium usually seen in spontaneous graft rejection. Where the transferred lymphoid cells are compatible with the tissues of the graft recipient, the picture is one of a severely affected graft on a field of uninvolved recipient corneal endothelium. Where the lymphoid cells are compatible with the graft and not with the tissues of the recipient, one sees a clear corneal graft surviving on a field of endothelial destruction on the recipient bed. The specificity of these reactions is illustrated in terms of the histocompatibility relationships between corneal donor, graft recipient, and the donor of the sensitized lymphoid cells.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
