چکیده

The process of wound healing of rabbit corneal endothelium involves the desquamation of significant numbers of endothelial cells, which may be found floating freely in the aqueous. It is suggested that this may be a general phenomenon of corneal endothelial wound healing, which accompanies the release of endothelial-cell attachments to Descemet's membrane and to neighboring cells during mitosis, allowing some of the cells to "fall of" into the anterior chamber. The possibility is discussed that such endothelial desquamation may contribute to had sensitization to he histocompatibility antigens of penetrating corneal grafts.

The fine structural changes in the corneal endothelium during graft rejection.

Fully penetrating corneal grafts were made between unrelated albino rabbits. Rejection was induced, and was regularly accompanied by invasion of the host cornea by superficial vessels. Advancing rejection was evidenced by stromal haze and thickening in the rejected portion of the graft. It was possible to study the clinically normal unrejected portion, the interface between it and the affected ...

Effect of Fas -670 A/G Gene Polymorphism on Corneal Allograft Endothelial Rejection

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

Diurnal Variation of Tight Junction Integrity Associates Inversely with Matrix Metalloproteinase Expression in Xenopus laevis Corneal Epithelium: Implications for Circadian Regulation of Homeostatic Surface Cell Desquamation

BACKGROUND AND OBJECTIVES The corneal epithelium provides a protective barrier against pathogen entrance and abrasive forces, largely due to the intercellular junctional complexes between neighboring cells. After a prescribed duration at the corneal surface, tight junctions between squamous surface cells must be disrupted to enable them to desquamate as a component of the tissue homeostatic ren...
