Purpose: To determine the extent to which each layer of the mouse cornea displays alloimmuno-genicity or immune privilege. Methods: Intact corneas or individual or combined layers of corneas from normal or cauterized eyes of BALB/c, C57BL/6, and CD95L-deficient B6-gld mice were grafted beneath the kidney capsule of normal BALB/c, B10.D2, BALB.B mice or of BALB/c mice presensitized to donor antigens. Graft fate was assessed clinically and histologically and acquisition of donor-specific delayed… 
Corneal Endothelium Confers Immune Privilege on the Cornea as an Allograft
TLDR
Both the epithelium alone and the stroma alone display immunogenic potential, whereas the endothelium confers immune privilege through constitutive expression of CD95L.
CD95 ligand expression on corneal epithelium and endothelium influences the fates of orthotopic and heterotopic corneal allografts in mice.
TLDR
CD95L expression on epithelium of full-thickness cornea fragment grafts placed in the anterior chamber of BALB/c eyes protects these heterotopic grafts from rejection but has only a trivial role to play in determining the fate of orthotopic corneal grafts.
Role of recipient epithelium in promoting survival of orthotopic corneal allografts in mice.
TLDR
Replacement of donor epithelium with Langerhans' cell-deficient syngeneic epit Helium protects orthotopic allogeneic cornea grafts (stroma plus endothelium) from immune-mediated rejection.
Immunologic mechanisms of corneal allografts reconstituted from cultured allogeneic endothelial cells in an immune-privileged site.
TLDR
Transplantation of corneal grafts formed with allogeneic CECs could be an ideal treatment strategy to overcome postoperative rejection and indicate that immunologic ignorance rather than active immunosuppression is important for the rejection-free acceptance of chimeric CEC allografts.
Survival in high-risk eyes of epithelium-deprived orthotopic corneal allografts reconstituted in vitro with syngeneic epithelium.
TLDR
Replacement of donor epithelium with syngeneic epithelial layers protects orthotopic allogeneic corneal grafts placed in high-risk eyes from sensitizing their recipients and from immune-mediated rejection.
New thoughts on the immunology of corneal transplantation
AbstractSignificant advances derived from rodent models of penetrating keratoplasty have transformed our understanding of the pathogenesis of rejection of orthotopic corneal transplants. The high
Dynamics of donor cell persistence and recipient cell replacement in orthotopic corneal allografts in mice.
TLDR
Whereas in mice graft-derived epithelium is largely irrelevant to corneal allograft outcome, persistence of donor-derived endothelium and keratocytes correlates perfectly with graft acceptance.
Long-Term Survival of Corneal Allografts Is Dependent on Intact CD1d-Reactive NKT Cells1
TLDR
CD1d-reactive NKT cells are required for induction of allospecific Tr cells and are essential for survival of corneal allografts and may lead to new therapies for improvement in graft survival in high-risk corneas and other transplanted tissues and grafts.
GITR ligand-mediated local expansion of regulatory T cells and immune privilege of corneal allografts.
TLDR
GITRL-dependent expansion of Treg within the cornea is one mechanism underlying immune privilege in corneal allografts.

Epithelium-deficient corneal allografts display immune privilege beneath the kidney capsule.
TLDR
It is inferred that the extraordinary success of orthotopic corneal allografts owes as much to the qualities of the graft as an immune-privileged tissue as to the quality of the eye as an Immune-Privileged site.
Impaired cell-mediated immunity in mice bearing healthy orthotopic corneal allografts.
TLDR
It is concluded that, when orthotopic corneal allografts are accepted indefinitely by adult mice, graft success correlates with the induction of alloantigenically specific anterior chamber-associated immune deviation.
Induction of anterior chamber-associated immune deviation by corneal allografts placed in the anterior chamber.
TLDR
Anterior chamber-associated immune deviation can be induced by allogeneic corneal tissue inserted into the AC, but its onset is delayed, and the delay may be dictated by persistence of donor epithelium on the graft, which promotes DH.
ORTHOTOPIC CORNEAL TRANSPLANTATION IN MICE—EVIDENCE THAT THE IMMUNOGENETIC RULES OF REJECTION DO NOT APPLY
The fate of orthotopic corneal transplants has been studied in inbred strains of mice. Using a surgical technique that achieves >95% success of syngeneic cornea grafts, it was determined that a high
Characterization of cell-mediated immune responses elicited by orthotopic corneal allografts in mice.
TLDR
It is proposed that minor H determinants are the most immunogenic alloantigens in orthotopic corneal grafts because they are the major source of peptides that will be loaded onto recipient class II molecules for T-cell recognition.
Interleukin 1 receptor antagonist suppresses allosensitization in corneal transplantation.
TLDR
Topical IL-1RA promotes corneal allograft survival in large part by preventing activity of recipient Langerhans cells, and thereby preventing these cells from inducing systemic allosensitization.
Immunobiology of Langerhans cells on the ocular surface. I. Langerhans cells within the central cornea interfere with induction of anterior chamber associated immune deviation.
TLDR
The results suggest that the presence of Langerhans cells in the central corneal epithelium mitigates againstACAID induction, suggesting that ACAID induction had not taken place.
On the Ia immunogenicity of mouse corneal allografts infiltrated with Langerhans cells.
TLDR
Results demonstrate that corneas, which normally lack both Langerhans cells and Ia-antigen expressing cells, can have their Ia immunogenicity restored if LangerHans cells are induced to infiltrate the epithelium.
Transplantation and rejection of individual cell layers of the cornea.
TLDR
Techniques have been developed for the transplantation of allografts of pure rabbit corneal epithelium and of endothelium with Descemet's membrane and only minimal amounts of adherent donor stroma that lead to sensitization of the recipient and to graft rejection when appropriate vascularization is induced.
Mechanisms of allograft rejection of corneal endothelium.
TLDR
Studying the local ocular GVH reaction in irradiated leukopenic recipients or in preinflamed rabbit eyes suggest that host leukocytes may contribute nonspecifically to enhance the destructive process.
