The Balance of Th1/Th2 and LAP+Tregs/Th17 Cells Is Crucial for Graft Survival in Allogeneic Corneal Transplantation

Figure 1

Survival of the grafts after corneal transplantation. (a) Kaplan-Meier survival curve showed that 15 of 40 allogeneic corneal grafts underwent acute rejection 4 weeks after transplantation, while there was no rejection in all syngeneic grafts. (b) The grafts were clear in the survival group while the grafts were severe opacity in the rejection group (magnification ×16). (c) Histopathology results showed that there was no edema and inflammatory cell infiltration in the survival group, while there was severe edema, inflammatory cell infiltration, and neovascularization in the rejection group (magnification ×10, bar = 50 μm).
